中国水土流失敏感性分布规律及其区划研究

Distribution and division of sensitivity to water-caused soil loss in China

以水土流失通用方程为理论基础 ,利用我国已有的水土流失研究成果及地貌、土壤和植被分布图 ,分析了降水、土壤质地、地形坡度坡长和地表覆盖因子对我国水土流失敏感性的影响及其形成的区域差异。在综合评价我国水土流失敏感性区域差异基础上 ,提出了中国水土流失敏感性区划方案。

Based on Universal Soil Loss Equation and maps of soil loss and topography, soil and vegetation in China, we assessed the influences of precipitation, soil texture, slope length and steepness factors, and land cover on sensitivity to soil loss by water and their spatial heterogeneity A sensitivity division of soil loss by water was proposed on an integrated assessment in China
