摘要

在中国水土流失和生态安全综合科学考察项目支持下

在综合科考的7大片区内

利用抽样调查方法结合GIS技术

依据水利部技术标准《土壤侵蚀分类分级标准》

依托国产水土保持专业GIS软件平台

研究提出了基于GIS的中国水蚀区土壤侵蚀后果危险度研究方法

总结了土壤侵蚀后果危险度分析评价的完整技术流程。实践证明

依据该流程完成的我国部分水蚀区危险度评价结果基本合理。本研究可为土壤侵蚀后果危险度研究及水土保持GIS软件模块开发提供一定参考。

Abstract

Based on an integrated scientific review of soil and water erosion and ecological security in China

the method for potential hazard degree evaluation of representative water erosion region in China based on GIS is proposed

and the whole technological process of potential hazard degree analysis and evaluation is summarized. Practice has proved that the evaluation result is reasonable

basically. The study can be used as a reference to the studies of potential hazard degree evaluation of soil erosion and the GIS development for soil and water conservation.
