基于RS与GIS的山西省主要煤田区土壤侵蚀研究

采用RS与GIS手段,选定土地利用、坡度、植被覆盖度作为土壤侵蚀分析的敏感性因子,利用GIS强大的空间分析功能,将各敏感因子叠加分析,对山西省主要煤田区域的土壤侵蚀情况进行了研究。结果表明,研究区土壤侵蚀以微度侵蚀和轻度侵蚀为主,微度侵蚀和轻度侵蚀分布区位积聚,主要集中在地势平坦、植被覆盖高、平原规整的农田以及居民区等建设用地;强烈侵蚀和极强烈侵蚀面积约占5%,分布较分散,主要位于坡度较大、植被覆盖低的山区以及沟谷地带。

Study on Soil Erosion of the Main Coalfield in Shanxi Based on RS and GIS

This paper studied soil erosion of the main coalfields in Shanxi by land use, slope and vegetation coverage as factors based on remote sensing and geographic information system methods, with the powerful space analysis function of geographic information system and soil erosion classification standard of classification published by Ministry of water resources. The results showed that the type of soil erosion in study area were mainly micro erosion and mild erosion and the erosion distributs in the flat large vegetation coverage area, plain neat of farmland or residential class construction land; serious and extremely intense erosion mainly located in large slope area with low vegetation coverage or broken country.
