THE MEASUREMENT OF THE LAND PRODUCTIVE POTENTIAL IN ARID AND SUMI-ARID REGIONS-TAKINGFUKANG COUNTY,XINJIANG PROVINCE,AS AN EXAMPLE
干旱与半干旱地区土地生产潜力的测定——以新疆阜康县为例

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.
