摘要

基于GIS和RS技术

采用修正版的通用土壤流失方程(RUSLE)

在对区域土壤侵蚀影响因子进行分析的基础上

对太原市土壤侵蚀进行定量研究

并根据土壤侵蚀强度进行了分级。结果表明

太原市土壤侵蚀以微度和轻度所占比例最大

主要分布在中南部的林地

以及东部和南部的以梯田为代表的耕地地带(坡耕地除外)

约占市区总面积的1/2以上。土壤侵蚀较严重的地带主要分布在北部以及边缘地带。其中

荒草地、裸岩石砾地等未利用地的侵蚀强度最大

其次是建设用地、水体和耕地

林地的侵蚀强度最小。总体上看

太原市大部分地区的土壤侵蚀程度相对较低

土地利用状况相对较为合理

但亦有一部分地区的土壤侵蚀较为严重

尽管所占面积较小

但不可忽视。

Abstract

Based on UIS and RS

a quantitative research on soil erosion in Taiyuan City is undertaken by RUSLE.The paper analyses the impact factors of soil erosion.At last

a new classification of soil erosion in Taiyuan City is put forward.The results show that most part of Taiyuan City are dominated by little or slight erosion

which is mainly distributed in the forest area in the middle and southern regions and in the arable land such as terrace
