为了比较不同单元之间的土壤侵蚀情况 ,在定义土壤侵蚀指数的基础上 ,利用遥感和地理信息系统技术 ,对重庆市不同背景条件下的土壤侵蚀情况进行了分析 ,具体表现在对不同坡度等级、不同坡向、不同高程带上、不同土地利用类型、不同土地利用方式、线状水体和面状水体不同缓冲带上的土壤侵蚀情况的分析。此外 ,还对重庆市各县的土壤侵蚀情况进行了分析 ,通过分析揭示出了土壤侵蚀与其背景的空间关系。
In order to compare the soil erosion between different units, based on the definition of soil erosion index, the paper analyzes the soil erosion under different background conditions in Chongqing using remote sensing and geographic information system technology, which is manifested in different slope grades , Different aspect, different elevation zones, different types of land use, land use types, linear water bodies and surface water bodies on different buffer zones. In addition, the soil erosion in all counties in Chongqing was also analyzed, and the spatial relationship between soil erosion and its background was revealed through analysis.
