| Abstract: | Based on multi-source remote sensing data,rainfall data,DEM and soil property data obtained in northern Hebei,the authors used Universal Soil Loss Equation(USLE) to make a quantitative analysis of soil conservation capacities with the support of GIS technique.Then the soil conservation capacities were converted into capital stocks by making reference to the Specifications for Assessment of Forest Ecosystem Services in China,which was stipulated on May 1,2008.Two kinds of ecosystem service values were consid... |
