Mining mineral resources will easily lead to destruction of land resources and deterioration of eco-environment in mining areas. In order to explore effect of coal mining on soil erosion and evaluate the situation of soil erosion in Liupan-shui, a major coal mining based city in Southwest Guizhou Province, based on related soil texture, terrain, meteorology, land cover and land use data, status quo and spatial distribution of soil erosion in the city was studied and characterized, with emphasis on distribution of soil erosion in the mining area using the RUSLE model and GIS spatial analysis method. Results show that the soil erosion in Liupanshui is mostly mild and moderate, with severe erosion distributed only in the east and south of Shuicheng County, the east of Liuzhi Special Zone and the central of Panxian County; that soil erosion mainly occurs in woodlands, meadows, dry lands, mining area and bare land where human disturbance is intense;that the mining area in the south of Liupanshui is quite severe in soil erosion as compared with others, but yet dominated with mod-erate erosion, mainly because mining activities triggers geological disasters which in turn lower the effect of soil erosion controlling factors;and that the situation of private-owned coal minings is much worse than that of state-owned ones. It is, therefore, important for private-owned coal minings to intensify protection and management of the land resources in the process of coal mining.%矿产资源的开采容易导致矿区土地资源破坏及生态环境恶化,为探索煤矿开采对土壤侵蚀的影响,分析矿区土地侵蚀状况.以贵州省西南部煤矿城市六盘水市为研究对象,基于土壤质地、地形、气候、土地覆盖和土地利用等数据,运用RUSLE模型,结合GIS空间分析方法,研究六盘水市土壤侵蚀现状及空间分布特征,着重分析煤矿区土壤侵蚀分布特征.结果表明:(1)六盘水市土壤侵蚀以微度、中度侵蚀为主,侵蚀严重区域主要集中在水城县东部和南部,六枝特区东部以及盘县中部.(2)土壤侵蚀主要发生在人类负向干扰活动强烈的林地、草地、旱地、煤矿区和裸地.(3)六盘水市南部煤矿区侵蚀较严重,以中度侵蚀为主,主要原因是采煤造成的地质灾害使土壤侵蚀抑制因素作用减弱.(4)私营煤矿区土壤侵蚀程度比国有煤矿区严重.私营煤矿区应在煤炭开采过程中加强保护与治理.
