摘要

综合分析了影响水土流失的各主要因子，如地表形态 (地貌、地面物质 (土壤及其母质、动力条件(降雨、径流、风力和冻融作用、人为活动影响 |结合现有的水土保持数据和研究成果，确定以土壤抗冲性、降雨侵蚀力、地形起伏度等作为基于GIS的中国潜在水土流失评价的指标，用以进行全国水土流失宏观分析评价。

Abstract

The main factors affecting the soil erosion are analyzed synthetically

Which includes meteorology

to-pography

soil

rainfall and human activity. Combined the data gained and the result researched

the grades of soil anti-scourablity

erode force of rainfall and relief of topography are confirmed as the indexes of China potential soil and water loss based on GIS

which could be applied on macro assessment of China soil and water loss.
