基于USLE模型的大小凉山地区土壤侵蚀定量研究
大小凉山地区 USLE 土壤侵蚀
2016/12/23
对四川省凉山地区土壤水力侵蚀状况进行定量研究，为该区水土流失调查提供数据支持。[方法] 利用四川省地理国情普查数据，基于对USLE模型的本土化研究成果进行分析和研究。[结果] 凉山彝族自治州平均土壤侵蚀模数为1207.67 t/（km2·a），土壤侵蚀面积为15221 km2，占该区土地总面积的25.19%。从空间分布上看其中金沙江沿岸是凉山彝族自治州土壤侵蚀最为严重的地区，其次是安宁河流域和黑水...

基于GIS/RS和USLE鄱阳湖流域土壤侵蚀变化
土壤侵蚀 水土保持 遥感 鄱阳湖流域
2011/6/15
将空间信息技术（RS和GIS）和通用土壤流失方程（USLE）相结合对鄱阳湖流域土壤侵蚀量进行计算。分别利用1990年和2000年TM/ETM+影像分类得到两期土地利用/覆盖类型图，结合鄱阳湖流域数字高程模型（DEM）、土壤类型分布图和流域降雨资料分别获取USLE模型中各因子值的空间分布，最后计算流域2个年份的土壤侵蚀空间分布图。研究表明：鄱阳湖流域土壤侵蚀区域主要分布在赣江上游，信江上游，抚河上中...
