摘要

土壤侵蚀强度与坡长、坡度、植被、土壤特性等诸多因子均有着密切的联系。利用传统方法对流域内各斑块的土壤侵蚀分级进行判定

效率低

精度差

误差大。结合有关土壤侵蚀强度分级标准

介绍了如何利用GIS空间分析功能

对矢量图形数据及小斑的属性数据进行分析和统计

从而得出流域面蚀土壤侵蚀分级图形

量化了土壤侵蚀强度分级过程

使此项工作更加科学化

现代化和合理化。

Abstract

Soil erosion intensity relates closely with many vegetation and the soil factors

including the length of the slope and slope gradient，etc. . For the reason that traditional method in classifying the soil erosion of different patches in a watershed is inefficiency and inaccurate. We introduces how to use the functions of thenGIS spatial analysis and characteristic data of patches，to get the soil erosion classification map of watershed refered to the soil erosion intensity classification criterion. This method can quantifies the process of soil erosion intensity classifying

and being more scientific

modernized and rationalized.
