基于GIS和USLE的土壤侵蚀定量分析研究——以四川省洪雅县为例
Quantitative Analysis of Soil Erosion Based on GIS and USLE——Taking Hongya County of Sichuan Province as a Case Study
摘要
Abstract
Taking the Hongya County of Sichuan Province as a case,based on the technology of geographical information system and the model of soil erosion degree,the status of soil erosion was analyzed and evaluated.Results showed that：there were significant differences of the land use units in Hongya County and the intensity of soil erosion was close connection with the different land use types.According to the land use status and the natural and economic conditions,the status can be divided into three intensity zones of soil erosion,which are slight erosion of northern area,micro-degree erosion of central area and no significant erosion of southwest area;corresponding water conservation measures were made for various different situations which can provide scientific basis for soil and water conservation planning for the local government.关键词
