摘　　要：晋陕蒙能源基地榆神府矿区,煤炭资源丰富,是我国重要的能源重化工基地。由于地处鄂尔多斯盆地东北部的黄土丘陵区和毛乌素沙地,自然条件恶劣,生态环境十分脆弱,水土流失是该区主要环境地质问题之一,而煤炭资源的大规模开发,必将加剧水土流失和环境恶化。根据1987年、1992年和1999年3期TM卫星遥感影像解译成果,在地理信息系统空间数据库功能的支持下,应用层次分析法,评价了该区水土流失现状,初步揭示了水土流失影响因素和发展规律。结合调查成果,研究了矿山开发等对水土流失的影响,并进行了初步预测评价,为该区环境保护和水土流失的防治提供了依据。Yushenfu coal mine has very rich coal resource and it is one of the key fuel energy and heavy chemical industry base in China. It locats in loesshilly area and Maowusu sandlot, northeast of Erduos basin, where have badly natural conditions and fragile environment system. Soil and water loss in natural environment is one of the main environmental geology problems in this area. Soil and water loss will become more seriously problem with large scale development of coal resources. According to three terms (1987,1992,1999) explaining results of TM remote sensing image, and under the support of database of GIS, the influence factors of soil and water loss and its trends are estimated by using arrangement analysis. A primarily forecasting and evaluating is made on coal mine exploitation that may affect natural environment based on the results of our survey. This would provide basic information for environmental protection.
