摘要
应用MODIS和TM／ETM＋等遥感数据可以定量反演矿区的土壤含水率。同时，在GIS技术的支持下，也可以由非采煤区推算出采煤区采矿前的土壤含水率。在构建神东矿区DEM的基础上，详细分析了矿区内的土壤含水率随高程变化的规律。研究结果表明，在单元水文地质区域尺度上，土壤含水率与高程成显著的负相关性关系；在矿区尺度上，土壤含水率与高程同样存在着显著的负相关性，但土壤含水率与高程的相关性明显减小，而且从1995--2005年，矿区的土壤含水率变化在低高程区域（900～1000m）有较大差异。
MODIS and TM/ETM ＋ remote-sensing data can be used to make qualitative inversion of the soil moisture content in mine surface layer. Meanwhile, under the support of GIS technology, the soil moisture content in coal mining area before the mining can also be deduced from that of non-coal mining area. Based on the DEM built for Shendong mining area, detailed analysis is made on the law of the change of the soil moisture content with elevation in the area. The result shows that on the scale of unit regional hydrogeology, the soil moisture content has evident negative relevancy with the elevation. On the scale of mining area, there is also a remarkable negative relevancy but a reduced relevancy between them. Moreover, between 1995 and 2005, there was a great difference in the change of the soil moisture contents in high and low elevation regions （900 - 1 000 m） in the mining area.
