摘　　要：以2011年和2012年获取的2期IKONOS2数据为信息源,在波段组合、数据融合和正射纠正等图像预处理基础上,针对矿山地质环境问题进行人机交互解译,对青海省木里煤田聚乎更煤矿区因煤矿开发而引发的矿山地质环境问题及矿山环境恢复治理情况进行了遥感调查与监测;并将矿山环境调查结果与矿区基础地理及地质资料相结合,根据矿区环境的实际状况,合理选择矿山地质环境评价因子及权重指标,对该矿区的矿山地质环境质量进行了动态评价。结果表明:聚乎更煤矿区的矿山地质环境质量呈明显下降的趋势,2012年采矿活动对矿山地质环境有影响的面积较2011年增加了近10 km2,主要是地表植被直接或间接地受到破坏,且矿山环境恢复治理工作进程远远跟不上矿山环境恶化速度。Taking the two-period IKONOS2 data acquired in 2011 and 2012 as the information sources, based on the band combination, data fusion and ortho-rectification, the authors made interactive interpretation of the mine geological environment problems, carried out the remote sensing investigation and monitoring work on coal mine environment problems and mine environmental recovery governance of the Juhugeng coal mining area in the Yushania coalfield of Qinghai, combined the mine environment survey results with the geographic and geological data of the mining area, and selected mine geological environment evaluation factors and weight indicators according to the environment condition of the mining area. The dynamic evaluation was conducted for the quality of mine geological environment. The results show that the mine geological environment quality of the Juhugeng coal mining area exhibits a downward trend, the area that affected the mine geological environment by mining activities in 2012 increased by nearly 10 km^2 as compared with that in 2011, the vegetation was destroyed directly or indirectly, and the process of the work to control mine recovery couldn’ t keep up with the process of mine environmental degrada-tion.
