    MARGINAL OPPORTUNITY COST(MOC) PRICING-THE THEORETICAL FRAMEWORK OF NATURAL RESOURCES PRICING

    The price of natural resources should be equal to their marginal opportunity cost(MOC).Theoretically,MOC is the whole cost of employing an unit of certain natural resource.MOC is made up of three parts:marginal production cost(MPC), marginal user cost(MUC) and marginal external cost(MEC).When we use an unit of certain scarce natural resource by some way,the maximal abandoned net benefit which may be gained from using the same natural resource by other ways is MUC. When we use an unit of certain natural resource,the Coverspending uncompensated loss that other people suffer is MEC.As an environmental resource,the self-puriflcation capacity of environment also has MUC.

    In this paper,we reconstruct the surface water resource of North Xinjiang in 250 years from the tree-ring field in this region,study the relationships among climate,surface water resource and tree-ring,analyze the long-term variation features and predict the variation trend in the futute.The main conclusions obtained are as follows:(a).Reconstructing the surface water resource from the tree-ring field in North Xinjiang has clear physiological significance and the results are believable;(b).The departure variation features of the sequence of the surface water resource of North Xinjiang in 250 years are as follows:the annual surface water is mainly less than its mean before 1840,it is mainly more than its mean from 1841 to 1974 and it is also mainly less than its mean after 1974:(c).There is an undulate increase trend in the surface water resource during 1760-1905 and there is a weaker decrease trend from 1905 to 1994:(d).The maximum departure percentage amplitude of the surface water resource in 250 years is from-29% to +41%;(e).The lengths of the main variation periods of the surface water resource are 2,35,30,14,and 52 years respectively;(f).There is a better correlation between the surface water resource of North Xinjiang and the relative number of sunspot in the periods of 22,11,6 and 2~3 years.

    A STUDY OF THE PRODUCTIVE ABILITY OF SOIL MOISTURE RESOURCE AND ITS UTILIZATION
    Yang Gaihe, Shen Yunxia, Tang Shuanhu, et al
    1996, 11 (2):  120-127.  doi: 10.11849/zrzyxb.1996.02.004

    The crop productive ability of soil moisture is studied by using the artificial moisture control under the climate in Shanxi Guanzhong.The results show that the highest soil moisture productive ability for wheat is 17.59kg/hm2.mm),for millet 11.61kg/(hm2.mm),for pea 10.33kg/(hm2.mm),and for rape 10.46kg/(hm2.mm).The critical value of soil moisture storage to obtain a certain output of wheat is about 160mm,of pea 150mm of millet and of rape 300mm.After the storage of soil moisture is over the critical value crop yield can be greatly improved with an increase of storage of soil moisture.But when soil moisture exeeeds a certain amount,crop yield tends to be stable.For example,for pea when soil moisture exceeds 300mm,for wheat 400mm,for millet 500mm,and for rape 650mm.Soil moisture productive ability can not raised when moisture is insufficient and fertilizer is abundant or when moisture is abundant and fertilizer is insufficient.At this time,the soil moisture ineffectively consumed.The soil moisture productive ability can be improved by applying fertilizer according to moisture conditions.

    AN EXPLORATION OF THE PATTERN OF THE GENERAL REGIONAL LAND USE PLANNING OF CHINA
    Wang Wei
    1996, 11 (2):  128-134.  doi: 10.11849/zrzyxb.1996.02.005

    On the basis of comparison and analysis of the practical situations of China and foreign counties,this paper establishes a pattern of the general,regional land use planning compatible to the socialist market economy system of China.This pattern consists of "zoning the land according to usage,setting up the regulations for regional land use and combining with the warning index of cultivated farmland".These are the core contents of the pattern.A logical control system consisting of "the macroscopic control level made of the regional land use strategy,the basic control level made of zoning the land according to usage,regional land use regulations and cultivated farmland warning index,and the applicaion control level made of public welfare land use planning"is established.

    This paper studies the agroforestry systems on slopes from the biomass and productivity, the energy conversion rate,the utilization rate of nutrient elements and the efficiency of value conversion.Moreover the comprehensive benefits of them are evaluated by using the AHP.The results show that in comparison with the farmland system,the agroforestry systems have the accumulative effect of biomass,energy,nutrient elements and value,and larger productive potential.Also the economic benefit and the utilization rate of auxiliary energy,solar energy and nutrient elements in the agroforestry systems are higher.In 8 systems,the comprehensive benefit of a platfoim agroforestry system is the best.

    This paper makes use of the observational temperature data of the meteorological stations of the mountainous areas in North China and their respective latitude,longitude and altitude to establish a macro-earth surface temperature field equation for each mountainous area.Using the topographic map on the scale of 1:200000,and taking each 10'(longitude)×10'(latitude) as the step length,we inteapret the altitude value and place it into the established equation.After the topographic corrcction, the annual and monthly mean temperatures the annual range and the Σ t'≥10℃ of the mountainous areas in North China are calculated.The accuracy reaches a very notable level.The results make us gain a new recognition about the thennal resources of the mountainous areas in North China.Finally,the upper planting limits of the best species of the main fruit trees are calculated.

    The Tibet Plateau is the main part of the Qinghai-Tibet Plateau.It is the highest plateau in the world and usually called"the Third Pole" because its average altitude is over 4000m.Numerous renowned rivers in Asia or in the world,such as the Changyiang,Lancangjiang,Nujiang,Irrawaddy,Yarlongzangbo,Indus Rivers,ect.,and interior waters, such as the Nam Co,Silling Co,Banggong Co,Yamzhonyum Co,Maphamyum Co Lakes,ect.,rise or flow here.They constitute a very complex water system.The special topography and harsh climate on the plateau make the ichthyofauna existing here show obvious regionality and unique.According to the composition and distribution of the fishes and the features of the regional natural geography relating to the fishery production in Tibet,three first-class fishery regions and five fishery subregions are divided.They are:(a).The Northern Tibet Region.It can be divided into three subregions:the Ngari Subregion,The Nagqu Subregion and the Qiangtang Subregion:(b).The Upper and Middle Yarlongzangbo River Region and(c).The Southeastern Tibet Region.It includes two subregions:the Lower Yarlongzangbo River Subregion and the Sanjiang Gorge Subregion of Eastern Tibet.

    This paper explores a method of estimating the relative available soil moisture(RAM) that supports plant growth.This is ased as a means to determine the land productive potential from the annual primary productivity a parcel of land can support.The method determines the RAM by using the multi-parametric fashion.The variable,include the ground-water table,soil depth,soil texture,slope and salinity.The primary productivity calculated by using these considerations gives reasonable agreement with the practically measured values.Therefore the estimates of the land productive potential in similar environments can be made by using the method.
