    Firstly, based on the existing research literature, combined with the principle of data availability, this paper analyzes the built evaluation index system for China’s regional mineral resources competitiveness, and measurement methods of each index are described. Then, using multiple indicators of input/output relative efficiency of complex systems approach-Data envelopment analysis (DEA) method, China’s regional (eastern, central and western) mineral resources competitiveness is assessed, the variation principle is revealed. Finally, with the region’s "competitiveness of mineral resources" and "GDP per capita growth rate" representing respectively the abundance of mineral resources, and the extent and level of economic development, whether inter-regional mineral "resource curse" hypothesis could be set up is verified. The results showed: 1) with the elapse of time and the development of China’s market economy, regional mineral resources continue to enhance competitiveness. In addition, China’s three regional mineral resources competitiveness and their own reserves of mineral resources are inversely proportional; and 2) the competitiveness of regional mineral resources and its growing economic development have stable equilibrium, two-way causality relation, that is the derived mineral "resources curse "hypothesis does not hold the conclusions.

    This paper selected 18 indexes in the three aspects of the status of comprehensive urban development, the demand and supply of logistics market, the foundation support conditions of logistics to build the comprehensive evaluation index system of logistics development. The synthetic evaluation of urban logistics competitiveness was calculated by factor analysis; using cluster analysis, the results were analyzed to determine the development level of logistics of every city; the administrative regions were divided into meshes by grid-partition method. The contraction coefficients were calculated respectively according to the speed limit of railways and roads of all levels, and the national road speed was taken as a standard. ArcGIS Workstation was applied to obtain the shortest relative distance between grid regional center and city, and the shortest relative distance among cities. Field intensity model was applied to calculate the field intensity of grid areas, and the value of logistics gravity among cities on the Western Coast of Taiwan Strait was measured. The result indicated that: the development level of logistics in Quzhou, Shangrao, Yingtan, Fuzhou, Ganzhou and Meizhou was low, and they were at the edge of the Western Coast of Taiwan Strait, which resulted in weak tie with other cities, so these cities were in the area with low field intensity, meanwhile they were cut off by the strong radial area of logistics which took the Pearl River Delta, Nanchang and Hangzhou-Shaoxing as core, so the formation and development of the logistics system of the Western Coast of Taiwan Strait were limited. Finally, establishing a hub-and-spoke logistic network was proposed in this paper. This network takes Xiamen, Fuzhou and Wenzhou as axis, other prefecture cities as fulcrum, the connecting line of Xiamen, Fuzhou, Wenzhou, Quanzhou and Shantou as main route. The attraction from axis cities to peripheral cities such as Quzhou, Shangrao, Yingtan, Fuzhou, Ganzhou and Meizhou is the key to develop this network.

    This paper analyzes quantitatively the land-use type shifts according to the differences comparison of history, present status and the planning with the data from field survey and the administrative authority,and argues the issue that the regional development trend is incompatible to the territorial function, which could contribute to the understanding of scientific issue to harmonize land use and serve the decision-making for future development. The paper analyzes numeric coordination, spatial coordination, main coordination problem and effect between current land use (2010) and function planning, using the overall coordination (C1) and effective coordination (C2) and other indicators, based on the territorial function and pattern perspective, taking Muyun Town of Changsha-Zhuzhou-Xiangtan (Chang-Zhu-Tan), combination as an example. It reveals the coordination characteristic and problem of the three types of the function space including ecological space, agricultural space and construction space, and then proposes the coordination policy. The results show that: land for construction grew rapidly in the recent years, while the agricultural land, forest land and countryside land declined dramatically. There were 426.67 hm2 of cultivated land and 359.24 hm2 of forest land decreasing, with the proportion declining by 6.58% and 5.53% respectively, and the growth weight heart of the town moved eastward rapidly and became a new development corridor rapidly as well. The index C1 of ecological space is 54% and the C2 is 69.81%, with a huge ecological space gap, so a larye area of 802.95 hm2 should be added to Muyun Town, the green heart construction should take more and heavier responsibilities and must focus on strengthening the northeast forest ecology and north greenbelt. The index C1 of agricultural space is 38.08% and the C2 is 91.28%, and the space conversion potential is greater, but villages land consolidation and renovation should be strengthened to enhance production efficiency and ecological service function. The index C1 of construction space is 36.11% and the C2 is 82.94%, and the construction land has being grown too fast and occupied a large amount of ecological space, threatening the ecological green heart function and pattern formation. Growth rate and spatial layout of construction space need to be adjusted and optimized. Research suggests that a three-layer security of the function space shoud be executed, population and urban-rural land should be integrated, and moderate complex function space and regional coordination mechanism should be constructed, in order to promote the coordinated development of land use and territorial function.

    Poor construction of rural irrigation infrastructure has been considered as one of the major reasons for increasing serious drought in agricultural production. The purpose of this paper is to evaluate the drought resisting effect of different irrigation infrastructures on grain production. On the basis of descriptive and econometric analyses, the paper quantitatively analyzes the effects of different irrigation infrastructures on drought resisting. The analyses are based on data collected from a large field survey with 1162 households from 123 villages in 7 provinces in China. Research results show that, in the recent five years, there were about 1/3 of farmers whose grain yield were damaged by drought. In addition, 22% of farmers lost grain yield by more than 25%. Among all irrigation infrastructures, larger and middle scale reseviors, ponds and water pump performed better than others on resisting drought. The paper also disscusses the policy implications of research results.

    Standard of payments for ecosystem services (PES) is one of the key issues to establish PES mechanism in watershed. The paper established research framework and calculation process of PES standard. Taking Weigan River Basin as a study area, by calculating ecological profit and loss, opportunity cost and willingness to pay, the maximum standard, minimum standard and reference standard of PES can be attained, which are 24.83?108 yuan, 0.24?108 yuan and 6.7?108 yuan. Based on the quality and quantity standards of water, cost-sharing model is built to compute the shares that counties of the lower reaches have to undertake. The results indicate that Kuche County has to pay 1.99?108 yuan, Shaya County 1.72?108 yuan, and Xinhe County 3.0?108 yuan. Standards of PES significantly affect welfares of farmers and herdsmen in watershed. The income of farmers and herdsmen in water conservation area will reach average level of basin, if they are compensated by 8.67% of reference standard of PES. In discussion, difficulties are analyzed during the calculation of PES standard in watershed.

    As wetland degradation is affected by natural, regional socio-economic development and many other factors, the comprehensive study of wetland ecosystem has attracted many scholars’ attention at present. To find the human factors in socio-economic development which affect the degradation of wetlands in China and predict its development trends, this paper attempts to reveal man-made factors that influence the degradation of wetlands by employing such methods as principal component analysis and regression analysis. The results indicate that three factors are connected with the human impact of wetland degradation including urban development (FAC1), rural production conditions, national infrastructure development (FAC2), and resource endowment (FAC3). By multiple linear regression, four indexes associated with wetland degradation are all influenced by FAC1 significantly (α=0.05), including area of wetland (Y1), surface water amount of resources (Y2), area of natural wetland (Y3) and the proportion of wetland to the country area (Y4). Y3 is closely connected to urban development(α=0.01); FAC2 exerts great influence on Y3 and Y4; and FAC3 affects Y3 notably. Based on the linear equations, the study forecasts development trend of wetland in the near future and puts forward suggestions accordingly.

    Locations of measurement plot in forest gap of Pinus koraiensis dominated broadleaved mixed forests in Xiao Hinggan Mountains were established by the method of grids. Extreme soil surface temperature in the gap was continuously measured during the growing season. Its spatiotemporal distribution patterns were analyzed and revealed by fundamental statistics and geostatistical method. The results showed that: the heterogeneity of extreme soil surface temperature existed among different locations in the gap. The intensity and scale of spatial heterogeneity changed over time and the complex degree of patch shapes were also different. The maximum soil surface temperature was the highest in June, then decreased in the sequence of July, August and September. The minimum soil surface temperature was the highest in July, then decreased in the sequence of August, June and September. The maximum and minimum values of mean monthly surface temperature were not fixed at the same location. The maximum soil surface temperature was the highest in the bare ground, medium in forest gap and the lowest in understory in the same month, the latter was the highest in understory, medium in forest gap and lowest in the bare ground. The aim of our study was to provide basic data and theoretical references for gap regeneration and sustainable management of Pinus koraiensis dominated broadleaved mixed forest.

    Growth of alpine plants is primarily limited by low available nitrogen in the soil. Both nitrogen addition and grazing affect soil nutrient availability and uptake of alpine plants, and consequently influence community productivity. To understand the effects of nitrogen addition and grazing on the ecosystem function, nitrogen addition experiment in combination with simulated grazing (clipping) has been conducted in an alpine ecosystem on the northern Tibetan Plateau since 2010. The levels of nitrogen addition in stimulated grazed (G+N) and non-grazed plots (NG+N) were controlled at 0 (N0), 10 (N10), 20 (N20) and 40 (N40) kg N穐m-2-1, respectively. Net nitrogen mineralization was measured by in-situ close-top incubation during the growing season in 2011. Nitrogen addition and clipping had different effects on the biomass allocation of alpine plants. Nitrogen addition mainly stimulated the above-ground productivity in non-grazed plots, but enhanced below-ground productivity in grazed plots. Although about 15%-20% of the above-ground biomass was removed by clipping, there is no difference of total biomass between grazed and non-grazed plots or even higher in grazed than non-grazed plots, owing to stimulating effects of nitrogen enrichment on the compensatory growth of alpine plants. Moreover, the different responses of biomass allocation to nitrogen addition and clipping were also reflected in the pattern closely related to soil nitrogen supply potential. Net nitrogen mineralization was negatively correlative with the above-ground biomass in non-grazed plots, but with below-ground biomass in grazed plots. It is indicated that alpine plants responded to soil nutrient and grazing by altering the allocation pattern of photosynthetic assimilates. The present study also suggested that in alpine meadow limited by available nutrient, nitrogen addition may stimulate compensatory growth of plants.

    The influences of grassland degradation on soil water retention were studied in the Junmuchang region of Maqin County, where is in the source region of the Yellow River, and the grassland degradation in this area is very serious. The methods of quadrates comparing different grassland degradation degrees were chosen in this research. Some important conclusions were obtained from this study, which mainly contained four aspects as follows. 1) Capillary water capacity and saturated water content were the biggest in the non-degradated grassland with a soil depth of 0-10 cm but the smallest in the extremely degradated grassland. While the capillary water capacity and saturated water content had no significant differences for both cases in 10-20 cm, and they were also the minimum in the extremely degradated grassland. However, the capillary water capacity and saturated water content in 20-30 cm were larger in the slight and serious degradated grassland, and they were relatively low in the non and moderate degradated grassland. 2) The field water capacity in the non-degradated grassland was much bigger than other grassland with different degradated degrees in the 0-10 cm soil depth. The field water capacity was relatively large in the slight and serious degradated grassland, but it was the minimum in the extremely degradated grassland. The field water capacity was relatively large in the slight and serious degradated grassland below a soil depth of 10 cm, and it was fairly low in the non and moderate degradated grassland. 3) Soil water retention had a close relationship with soil physiochemical properties, and they were mainly affected by the bulk density, organic matter, total nitrogen and total carbon. 4) The land-cover, biomass amount and distribution characteristics of plant roots with different grassland degradation degrees could induce the changes of bulk density, organic matter and so on, and would be possible to result in the changes of soil water retention. This research could provide the scientific basis for the study of the impacts of grassland vegetation degradation on soil hydrological and ecological effects.

    Based on daily temperature(maximum and minimum)and daily precipitation at 124 meteorological stations over Northwest China observed by the China Meteorological Administration during the 1960-2009 period, the variability of extreme events of temperature and precipitation over Northwest China in recent 50 years is analyzed and its extreme climatic variation in future is predicted. Eight indices of extreme temperature and six of extreme precipitation are studied. Over the 1960-2009 period, the occurrence of summer days, growing season length, hot night days and maximum temperature days have significantly increased by 2.31, 2.98, 1.07 and 0.45 days/decade, respectively. Over the same period, the regionally averaged occurrence of extreme ice days, consecutive frost days and minimum temperature days have significantly decreased by -2.51,-1.79 and -3.62 days/decade, respectively. The annual temperature range also exhibits a decreasing trend (-0.39℃/decade). With the exception of diurnal temperature range, the other indices correlate with annual mean temperature very well. Precipitation indices about annual maximum with 1-day and 5-day precipitation, consecutive dry days and averaged daily rainfall intensity have no statistically significant increasing trends while the number of heavy precipitation days and consecutive wet days decrease. At the same time, there are significant correlations between annual total precipitation and precipitation extremes except consecutive dry days. In spite of the above-mentioned main trends and correlations in most parts, the differences in spatial distribution and different climatic regions still exist significantly.

    Glacier change of Altay Mountain in China during the past 50 years was analyzed based on the outcome of Investigation of Chinese Glacier Resources and Their Changes and result of the First Glacier Inventory of China. The results showed that glaciers had been retreating in Altay Mountain in China from 1960 to 2009. The number of decreased glaciers reached 116, the area reduced 104.61 km2 and the volume loss was 6.19 km3. Compared with glacier change in other mountains in China, the annual average rate of glacier recession was the maximum in Altay Mountain where thus was the strongest region of glacier shrinkage. From the respect of glacier orientation, glaciers retreated in every direction. The maximum loss of glacier area occurred in north direction and the minimum appeared in west direction. The number and area of glaciers showed an obvious decrease tendency at altitudes of 2400-2600 m, 2600-2800 m and 3000-3200 m. The most remarkable shrinkage of glaciers occurred at an altitude of 2600-2800 m. Glacier change had a regional difference. The number and area of glacier retreat decreased most in Burqin River watershed where the glaciers were concentrated. However, there was an inconsistency between number and area reduction of glaciers in other watersheds. The recession or disappearance of a large amount of small glaciers was the main cause of regional difference of glacier change. There was a close relation between glacier recession and climate change in Altay Mountain. The average temperature from May to September and precipitation from October to April in the next year from four meteorological stations in the study area both increased. The glacier recession in this region indicated that supplies to glaciers by increases in precipitation did not compensate for ablation rate increases caused by the dramatic temperature rise during the study period.

    As an important department of urban service industry, urban tourism is a subsequent power which promotes the urban development. Using the methods of Entropy and TOPSIS, the paper analyzes the coordination level between urban tourism and urban development in 2003 and 2008 of the Yangtze River Delta in six aspects: economic level, social development, public transportation, urban afforestation, environmental protection and tourism development. With the help of ArcGIS software, it uses the spatial clustering method, studying the spatial pattern and evolution of coordination level between urban tourism and urban development. The results show that the urban tourism coordination level has a good stability in 2003 and 2008, and the cities in the Yangtze River Delta can be divided into four levels. The number of the cities of the first and the second levels is less, but their scores are higher than the cities of the third and the fourth levels. The city number of the third and fourth levels is much more which accounts for more than 70% of all cities. Since 2003, the cities with higher levels of urban tourism coordination include Shanghai, Hangzhou, Suzhou, Wuxi, etc., scoring between 0.2-0.9, and the lower level of the cities include Jiaxing, Shaoxing, Zhoushan, Taizhou, etc., scoring lower than 0.2. The urban tourism coordination level of Shanghai is significantly higher than the other 15 cities, demonstrating that disparity of tourism development level is obvious. There is a larger spatial differences in the coordination level between urban tourism and urban development, the cities in the north score higher than that in the south, and the spatial distribution pattern remains stable: Shanghai, Nanjing and Hangzhou are the core cities in the Yangtze River Delta according to the score of urban tourism coordination level, presenting an attenuation properties from the core cities to the periphery and the edge cities. Industrial development, the development pattern of urban tourism, the major project investment of urban tourism and location are the main influential factors that contribute to the spatial distribution differentiation on the coordination level between urban tourism and urban development in the Yangtze River Delta, which can be targeted to the formulation of the urban tourism as a means of promoting urban development way, so as to promote the regional balanced development.

    Accurate knowledge of the geographical distribution of the direct irradiance over an area of interest is important for the solar energy assessment and management. Because stations for measuring solar irradiance, cloud and sunshine hours are scarce in Northwest China, a method must be developed to estimate the direct radiation. An enhanced broadband direct irradiance model based on several satellite data, such as NCEP/NCAR data, the Chinese FY-2C geo-stationary meteorological satellite data and the NCEP/NCAR Reanalysis 1 Project data sets, is presented in this paper. The method, originated from Bird clear-sky model, firstly calculates the radiative transmittances for clear skies, and then calculates direct irradiance for cloudy conditions. To calibrate the model and evaluate its performance, five ground stations in Northwest China, where the direct irradiance are routinely measured in 2006-2007, are used for model calibration and verification. The simulation result shows that the estimated daily direct irradiance correlates well with measured direct irradiance at the five stations, with the Nash-Sutcliffe Cofficient of Efficiency(NSE) 0.68-0.8. The performance of the monthly average daily direct irradiance reveals that the result from April to October is better than that from November to March.

    Based on IPCC’s reference approach for carbon dioxide assessment, the paper calculated and compared the indicators including total CO2 emissions, per capita emissions, emissions intensity and integrated energy emission factors from 2005 to 2009 for 30 provinces in China. On the basis of relationships between CO2 emission intensity and per capita GDP, the proportion of secondary industry and the structure of energy utilization, 30 provinces have been classified into several different emission groups. It has been found that significant differences in key indicators exist among provinces, and the major factors controlling provincial carbon emissions are not completely the same. Therefore, the level of economic development, industrial structure, the structure of energy utilization and other factors should be fully considered when developing policies, approaches and measures for provincial emission reduction.

    Contingent valuation (CV) method is an important method in environment and resource valuation assessment, and follow-up certainty question is just one of the convenient and effective measures to enhance CV validity. We illustrated contingent valuation calibration using follow-up certainty question with a 10-point Likert quantization table by a case study of Gushan scenic area non-use value assessment. We employed double boundary dichotomous choice elicitation. The experiment was conducted face to face, and produced a total of 518 valid questionnaire samples. The action certainty of respondents with positive willingness-to-pay for Gushan Protection Society were normal distribution with mean certainty 6.72. Respondent’s income and his familiarization to Gushan scenic area were significantly positively related to his action certainty, and his action certainty is sensitive to the initial bid. Respondents’ positive willingness-to-pay dropped from 51.5% to 27.8% or 23.3% respectively when certainty threshold value was 7 or 8, and mean willingness-to-pay dropped from 33.24 yuan to 19.74 yuan or 16.36 yuan accordingly. CV result falls by half by follow-up certainty question calibration.

    Some remote sensing drought indices are being widely used in northern China, but seldom in humid regions of southern China. This takes takes Hunan Province as a study area. Based on RS, GIS and additive combination of Enhanced Vegetation Condition Index (EVCI) and Temperature Condition Index(TCI) from MODIS data, it gave different weights according to the sensitive degree of drought information and established Drought Condition Index (DCI) model. And then the spatial distribution maps of agricultural drought situation grades were obtained. Finally, based on the meteorological drought composite index (CI) from 97 meteorological stations, the correlation was analyzed. The results showed that the linear correlation between drought situation-monitoring model, which was set up on LST and EVI, and CI was significant, the higher weight was assigned to the TCI in the DCI model. And the DCI based on remote sensing data to monitor drought dynamic change still has some reference value.

    The world is currently threatened by considerable damage to or losses of many natural resources, including fisheries, lakes, and forests, as well as experiencing major reductions in biodiversity and the threat of massive climatic change. Understanding of the processes that lead to improvements in or deterioration of natural resources is limited, because scientific disciplines use different concepts and languages to describe and explain complex social-ecological systems(SESs). Based on collective lectures about Common-Pool Resources(CPRs) management and Social-Ecological Systems(SESs) analysis framework, the concepts of CPRs and SESs were reviewed and analyzed. After identifying the variables which impact the sustainable development of CPRs, the paper presented the evolution and limitation of the framework for analyzing sustainability of SESs. Three stages were summarized, as the institutional analysis and development framework, the diagnostic framework and the framework for analyzing sustainability of SESs. The framework for analyzing sustainability of SESs provided a unified platform which is helpful for the integration of geography, ecology, economics, environmental science, sociology, and other disciplinary. And it also provided a variety of new methods and ways of thinking for resource management, policy analysis, comparative case analysis.
