    As forests and the harvested wood products (HWP) have carbon sequestration function in mitigating the global climate change, the carbon storage of HWP has become an important issue in global climate negotiations. To study the carbon storage function and the management strategy of HWP has important practical significance for China to present the national greenhouse gas emissions list and improve the potential of greenhouse gas emission reduction. This paper first decomposed the principle of carbon storage and emission reduction of HWP for climate change mitigation. The hysteresis effect of carbon emissions decides that the HWP are carbon pools. The HWP have big effects in reducing carbon emissions, especially in energy and building department. The paper then made a comparison of four carbon accounting models of HWP provided by the IPCC Guidelines, and Stock-change approach and Atmospheric-flow approach were used to estimate the annually carbon storage change of HWP of China during the period from 1961 to 2011, and finally evaluate the carbon reduction potential of China's HWP through comparative analysis. The carbon conversion variable factors needed in the accounting process referred to "2006 IPCC National Greenhouse Gas List Guide", and China's wood products production and international trade data got from the FAO database. From the angle of total amount, the carbon storage of HWP was 676 million t and 258 million t in 2011 using the Stock-change approach and Atmospheric-flow approach. From the angle of annually growth, the result of Stock-change approach and Atmospheric-flow approach was 10.63 million t and 2.62 million t during the period from 1961 to 2011. As China is a large wood products importing country, the result shows that the Stock-change approach is more beneficial to our country than the Atmospheric-flow approach. Contrast to China's forests carbon storage during the same period (1973-2003), the proportion of carbon storage in the HWP was 4.75%-8.42%, at an average of almost 6%; Contrast to the data of carbon dioxide emissions from the consumption of energy provided by U.S. Energy Information Administration, the carbon storage in the HWP could reduce about 1.6% of total emissions. China's HWP have significant function of carbon storage and further potential in carbon emissions reduction.

    This paper aims to explore the definition, classification and evolving principles of the cooperation models in international river management (referred to IRMCMs thereafter). IRMCMs imply the element system comprising the main bodies, objectives, contents, manners, approaches, regimes and mechanisms in cooperative management on the development and utilization and protection of international rivers, which is established by the riparian or basin countries in certain contexts of natural geography, politics and economy and social society. IRMCMs can be abstracted and outlined from characteristics of either a certain element or some or all the elements. Based on one-dimensional classification of IRMCMs in respects of cooperative bodies, objectives, approaches and regimes, this paper further carried out a three-dimensional (comprising cooperative bodies, objectives, and regimes) classification of IRMCMs by using a systemic analysis method of A.D.HALL three-dimensional structure figure in order to present various models which can reflect the existing cooperation practices in international river management completely and correctly. Finally, this paper outlined the evolving principles of IRMCMs from respects of model element development and model evolving dynamic mechanism, based on overview of the process of formation and development of various typical IRMCMs.

    With the development of remote sensing technology, it has become an important technical means used to investigate vegetation biomass. The biomass of wetland vegetation is an essential index to describe the wetland ecosystem of primary productivity. Therefore, the investigation of wetland vegetation biomass has important practical significance. In this paper, the core area of the Yancheng Natural Reserve was selected as the study area. The ETM+ image on September 24, 2011 and 31 samples of biomass data in the same period were used as the data source to establish the estimation models. The correlation between the 15 remote sensing information variables and measured biomass were analyzed in this paper. The remote sensing information that showed significant correlation at level 0.01 was selected and the estimation models were established based on eight remote sensing information variables. The models included the simple regression models, the curve regression models and the stepwise regression models, the best estimation models were obtained. The total aboveground vegetation biomass of the study area could then be calculated by the best model in this paper. The conclusions of the study were as follows: 1) Both biomass dry weight and fresh weight of the study area has the best positive correlation to the ETM + 4. The coefficient of biomass dry weight was 0.833 and the coefficient of biomass fresh weight was 0.796. 2) A one variable cubic function model was used by both the biomass dry weight models and biomass fresh weight models. The biomass dry weight models were better than the biomass fresh weight models. 3) The total biomass dry weight of the study area was 2.28×108 kg and the biomass fresh weight weights 6.10×108 kg based on the best estimation models. In this study area, dry biomass was mainly between 1000 g/m2 and 3000 g/m2 and the humid biomass was mainly between 3000 g/m2 and 6000 g/m2. There was little extreme high biomass for both dry weight and fresh weight, which was mainly distributed in the places of Spartina alterniflora. The weight of S. alterniflora biomass was more than the reed biomass, and that of the reed biomass was more than the Suaeda salsa biomass. The low weight was distributed in places of Suaeda salsa and around the culture pond and neighboring bare flat.

    Aboveground biomass of wetland vegetation is closely related with wetland ecosystem productivity, carbon cycle and nutrient cycle, and so on, is one of the main concerns in the present study. The canopy hyperspectral reflectance data of two tidal marshes dominated respectively by Phragmites australis and Cyperus malaccensis Lam. var. brevifolius Bocklr. was determined by ASDFieldSpec 2500 in the Shanyutan wetland in the Minjiang River estuary in October 2011 and October 2012, and the aboveground fresh biomass and plant density of the two marshes were collected simultaneously. The correlation between canopy reflectance, first derivative spectra and aboveground fresh biomass of P. australis and C. malaccensis was analyzed. The sensitive band was confirmed so as to improve vegetation index. Furthermore, using the regression analysis method, based on various vegetation indexes, the aboveground fresh biomass and plant density estimation model was constructed. The results showed that the aboveground fresh biomass was more closely correlated with the two marshes canopy reflectance in blue, red and near infrared band, and was relatively well correlated with first derivative spectra at blue edge and red edge. No matter canopy reflectance or first derivative spectra, the correlation of P. australis is better than C. malaccensis. Compared with other parameters, BNDVI, NDCI and MGBNDVI also have higher estimation accuracy of aboveground fresh biomass for both species, and BNDVI was the best estimated parameter of aboveground fresh biomass for both species and the estimation accuracy was higher for P. australis (R2=0.4085-0.765), while for C. malaccensis R2 ranged from 0.1019 to 0.3153. Furthermore, GBNDVI, BNDVI, MGBNDVI, NDCI and SR also have higher estimation accuracy in plant density for both species, and there is a higher plant density estimation accuracy for P. australis as well (R2=0.0930-0.718), while for C. malaccensis it ranges from 0.1389 to 0.2337, and the best estimate parameter are GBNDVI and NDCI respectively. To some extent, it is feasible to use remote sensing data to estimate aboveground fresh biomass and plant density based on the models built in this work.

    This paper builds the evaluation indicator system for water use efficiency and coordinated development of economy coupling in Liaoning coastal economic belt (LCEB). Firstly, using improved mutation model to evaluate status of LCEB water use efficiency and the economic development of each subsystem from 2001 to 2010. Secondly, using coupling coordination model to evaluate water use efficiency and the coupling coordination degree of economic development of every city of LCEB. The results show that the coupling degree of water use efficiency and the economic development of LCEB increased from 0.437 to 0.498, which is slowly improving, but it has been in the stage of resisting. The gap of water use efficiency and economic development level decreases continuously, and the coupling coordination degree increased from 0.254 to 0.408, which showed a trend of increase but still at the mid-low level of coordination. Water use efficiency and economic growth of every city of LCEB are in a rising trend, water use efficiency of Dalian is the best with an evaluation value reaching 0.887, Jinzhou, Yingkou and Huludao are in the second place, Dandong and Panjin at the worst level with evaluation values being 0.604 and 0.535. The economic development level of Dalian is the highest, Yingkou and Panjin are at intermediate level, Dandong, Jinzhou and Huludao are at the lowest level. The coupling degree of every city in the stage of resisting, and in a rising trend. The coupling coordination degree of Dalian and Yingkou have reached 0.457 and 0.401, and entered the stage of moderate coordination from low-grade coordination phase,and showed a rising trend. The coupling coordination degree of Dandong, Jinzhou, Panjin and Huludao still at the low level of coordination and showed a fluctuated increase.The economic development of every city falls behind the improvement of the efficiency in water usage, which causes the coupling coordination being in the mid-low grade period. The regional disparities among the coupling degree and coordination degree of LCEB are decreasing, and the coordinated development trend of economic belt becomes more and more apparent.

    In the background of warming in recent decades, glaciers on Earth are rapidly melting. Mountain glaciers in China have also changed dramatically. The changes in mountain glaciers will affect the Earth's ecological environment and human living environment directly or indirectly. Therefore, monitoring the changes of mountain glaciers is essential. The expansion and contraction of glaciers in Geladandong very clearly reveals the Qinghai-Tibet Plateau and the local and global climate change. This paper summarizes the research status in combination with the available knowledge. Using five periods Landsat data with application of snow index and supervised classification method, glaciers information was extracted, then, using spatial analysis techniques, the change detection for the range of the extracted glaciers was made. Glacier advance and retreat information during the four periods of 1973-1986, 1986-1992, 1992-2004, 2004-2009 as well as 1973-2009 time period throughout the 36 years were obtained. The rate of change of glacial advance and retreat was calculated and detailed statistical analysis of five glaciers with greater changes was conducted. The results showed that both glacial advancement and retreatment existed. From 1973 to 2009, the area of glacial advancement was 62.66 km2, while the area of glacial retreatment was 118.64 km2. The total areas of the glaciers had decreased continuously. The temperature has been rising over the "Sanjiangyuan" region in recent 40 years, which is the key factor leading to the continued retreatment of the Geladandong glaciers.

    No "stationarity" exists in the environmental background for the formation of many river flood series in the world any longer, and the traditional extreme value flow analysis, i.e. "extreme value theory" must be amended in order to adapt to these phenomena. The annual maximum peak flow of Longchuan and Heyuan stations in Dongjiang River Basin exhibited a decreasing trend at the significance level of 0.01 detected by Mann-kendall test after hydraulic engineering regulation. In this study, the non-stationary processing method of time-varying moments (TVM) was adopted to analyze and calculate the annual maximum daily flow series at Longchuan and Heyuan stations of the Dongjiang River Basin. Five types of distribution curves and eight kinds of trend models, for a total of 40 models, were selected for comparison. The results showed that lognormal distribution (LN2) with a CP model (CP refers to both the mean value and standard deviation have a parabolic type trend and the ratio of the two is constant) at Longchuan Station, Gumbel distribution with a CP model at Heyuan Station may obtain the optimal fitting effect. After significant changes occur to the hydrological regime, the concept of tradition flood should be amended. Based on traditional frequency analysis methods, the design value of 100-year flood was available, indicating that a return period changed from less than 100 years before hydraulic engineering construction to 400 years after 2000 at two hydrological stations, rather than 100 years, for both stations. In the context of non-stationarity, the flood design value corresponding the present time points should be recommended.

    A model was constructed to estimate the clear sky global solar radiation via FY-2 Weather Satellite data with the consideration of sun, topography, snow cover, cloud cover as well as the influence of heterogeneous atmosphere. And the performance of this model was examined with the application of hourly, daily and monthly solar radiation data (observed in 2011) from three observation sites located in Shanxi Province. Results indicated that the relative errors of hourly estimations were ±1 MJ·m-2 and that of daily estimations were ±5 MJ·m-2, i.e. the estimation of this model was satisfied with small errors as well as stability. As to the analysis of monthly performance, the estimations of the three observation sites were higher than the observations but all of these estimations were with similar error distributions as well as same characteristic of larger errors in winter than that in summer. And the perfect goodness-of-fit of 0.86 to 0.92 and high correlation coefficients meeting significantly correlated level were also investigated by the further correlation analysis between the estimations of this model and the observations and that further show the high accuracy and precision of this model which could output satisfied global solar radiation and thus verified the feasibility of the application of this model with FY-2 Weather Satellite data.

    In the paper the author evaluates tourism development suitability of hot spring resources by taking Hunan Province as a case. Indicators are selected strictly in accordance with the system of tourism destinations, the system of tourism transportation, the system of tourist markets(three subsystems of tourism system), and constructs evaluation index system and evaluation module. The system of tourism destinations is divided into two sections (hot spring resources and regional environment). According to the possible position scope of tourist markets, hot springs are regarded as the centre of circles calculating average travelling time from random positions within the radius of limiting different kilometers to hot springs and look on it as indicators of the system of tourism transportation. Because of the limitations of tourist capacity of hot spring resources and the power of tourism attraction, the overwhelming majority of tourist markets are limited to a travelling region of four hours, and the author thinks the county-level towns within the travelling region can be taken as tourist markets of hot springs.#br#Next, the author adopts Analysis of Hierarchy Process (AHP) method and information entropy method to evaluate the weights of the index system, and calculates the indexes of all hot springs to acquire comprehensive value of tourism development suitability of hot spring resources in Hunan. Further, tourism development suitability of 90 hot springs in Hunan is classified into three types of high suitability, medium suitability and no suitability. Finally, the author puts forward many reasonable development proposals in view of every type of hot spring tourism resource.

    The study aimed to observe physical and chemical properties of lateritic red soil under different land uses in South China, such as pH, clay contents, bulk density, porosity, organic carbon, total contents of nitrogen, phosphorus, potassium and their available contents. Relationships between these variables, soil quality under different land uses and their main key factors were evaluated by principal component analysis (PCA). Results showed that: the highest bulk density in soil and the lowest clay content and porosity were observed in the newly cultivated dryland; while the lower contents of soil organic C, total N, P, K, available N and P were found as well (P<0.05). The orchard soils have the lowest bulk density in these four kinds of land uses, and higher contents of total N, available N, P and K were showed in our study (P<0.05). Compared to shrub land, the eucalyptus forest soil has higher total and available K contents but lower clay and available P contents, respectively (P<0.05). PCA results showed that significant differences in soil physical and chemical qualities were observed in newly cultivated dry land, orchard land, eucalyptus forest and shrub land (P<0.05), especially the lowest quality were found in newly cultivated dry land. Lower contents of organic C, nitrogen, available N resulted in the lower soil quality of the newly cultivated dry land. In the meantime, lower contents of available P and K limited the improvement of soil quality in eucalyptus forest and shrub land. PCA can not only distinguish physical and chemical properties of lateritic red soil under different land uses, but also can detect their main factors.

    To study the characteristic of water quality and water resources in Yutian, Xinjiang, China, the element content of drinking-water was measured by hydride generate atomic fluorescence spectrometry (HG-AFS), ICP-OES and ICP-MS. A high quality natural drinking water (hydrochemical type: Na·Mg-HCO3·Cl) of Li-rich and Sr-rich was found in Yutian County, Xinjiang. The concentrations of Li and Sr in drinking water were 1765.5 μg/L and 1.1mg/L respectively, which were 8.8 times and 5.5 times that of the lowest limit of drinking natural mineral water standard (Li ≥ 200 μg/L and Sr ≥ 0.2 mg/L), respectively. The concentrations of total dissolved solid (TDS), total hardness (TH) and other trace elements were within safety range. The aquifer is the Quaternary gravel formation, with good permeability of water and relatively abundant groundwater resources. Drinking natural mineral water in Yutian was rich in Li and Sr compared to others of domestic and overseas. Mineral water with Li-rich is scarce in China. It is worth exploiting as a drinking mineral water.

    Based on data from beam shrimp trawl net surveys in four seasons of 2008 and 2009 in the East China Sea (26°00'-33°00'N, West of 127°00'E), we used CPUE (catch per unit effort) as the index for quantitative distribution of Stomatopod, and analyzed the changes of species composition, and quantitative distribution of Stomatopod in the East China Sea. The result shows that: 20 species of stomatopod were found in the survey area, belonging to 4 families and 11 genuses, Oratosquilla oratoria and Oratosquilla kempi were dominant species. The number of species in spring is the highest among four seasons, and the rest varied unconspicuous. The yield of catch and CPUE in each season varied obviously, those were the highest in winter, and then summer, spring, autumn successively. According to the distribution of each area, the number of species and biomass was higher in the southern East China Sea than the other two areas. Though both the Stomatopod and Oratosquilla oratoria had relatively high occurrence areas of biomass in four seasons, they were all unconspicuous. The distribution of Oratosquilla kempi showed regional characteristics.

    Water resource transfer not only affects the efficiency and effectiveness of water resource use, but also influences the fairness and sustainability of water resource use for different users. To scientifically and reasonably calculate the compensation for water resource transfer, a model which calculates compensation of water resource transfer is built in this paper. Factors including the contribution of income, the capital, efficiency of water use, the risk and the fairness for the cooperators are all synthetically considered in the model to determine the profit-sharing in the water resource transfer. The weights of influencing factors are creatively calculated by the method of rough analytical hierarchy process (RAHP). On this basis, the profit-sharing and compensation amount of the water resource transfer are calculated. The economic and social objectives are integrated in the model for calculation of compensation in water resource transfer. The social factor (social justice) included in the index system of income distribution, along with the economic factors indicators, are regarded as an objective of the decision on compensation for water resource transfer. It makes the decision-making index system in the model being closer to the practical multi-objective decision-making situations. The Chenshi Irrigation District in Zhuji city is taken as an example. The paper introduces the model which calculates compensation of water resource transfer to redesign the index system of income distribution and the interest compensation among the main bodies of the water resource transfer. The case study from Chenshi Irrigation District verified the feasibility and validity of the model. The case study shows that the weight of contribution of income and the capital on income distribution are 0.321 and 0.383 respectively which have a greater impact on income distribution than other factors. And the weight of social justice is 0.116 which also accounts for a large proportion of income distribution. Thus, the weight of social objective should be fully considered in the index system of income distribution to reasonably determine the compensation among the participating bodies in water resource transfer. And the case study also indicates that the amount of interest compensation for agricultural water resource users in practice is far less than what agricultural water resource users should gain based on the calculation result from the model. Then, it is urgent to raise the interest compensation for agricultural water resource users in water resource transfer.

    Based on the research of the efficiency problem concerning internal and external agricultural land consolidation project, we defined the connotation of the early stages of the efficiency of the agricultural land consolidation project and analyzed the value chain, and the value-added chain around the core, in which we set the early stage of the work efficiency index system of the agricultural land consolidation project which contains five criteria layers concerning the project site investigation, feasibility study, reconnaissance, the ownership adjustment and the planning and design. We set up the benchmark of 32 efficiency indicators based on the principle of benchmarking and project characteristics, set up the actual optimal benchmark and the theoretical extension benchmark, build up the measure model, which is based on the distance function of agricultural land consolidation project in the early stage of the work efficiency. Taking Putuan in Huarong District of Ezhou City productive farmland building demonstration projects as an example, we measured the efficiency of its early stage. The results showed that: 1) the work efficiency of the early stage of the project at or close to the reference benchmark reached the norms and standards reference value; 2) according to the actual optimal benchmark, the comprehensive distance value is 0.1940, the efficiency of the early phase of the project relative to the actual optimal benchmark level is higher, with a certain distance from the actual optimal benchmark; 3) according to the theoretical extension benchmark, the comprehensive distance value is 0.2528, the efficiency of the early stage of the project relative to the theoretical extension benchmark level is low, with a certain distance from the theoretical expansion benchmark. Based on the measurement results the existing problems in the aspects of the completeness of the program, the validity and rationality of the work performed were analyzed, and suggestions were put forward: 1) attention should be should paid to the project site link with the added cultivated land potential and the contiguous focus degree of the field, in order to improve the effectiveness of the implementation of the pre-project stage work; 2) motivate farmers to participate in, at the same time, it needs to strengthen the close integration of the agricultural land rectification and agricultural industry so as to improve the completeness of the planning and design work program; 3) ownership adjustment link should be given full play to the initiatives of village collective organization or cooperative organization and its effect on the organization so as to avoid the deficiencies in the work program, in order to improve the completeness of the work program. This work provides reference for other agricultural land consolidation project in the early stage of the efficiency measurement.
