| 摘 要： | 采用加权综合指数法,基于地理信息系统(GIS)技术,综合评价了北京市矿山地质环境并对成因进行分析。结果表明:北京市矿山地质环境呈现不平衡的空间分布特征,较差区分布在西南部(位于门头沟和房山区内)及北部(位于密云县和怀柔区内),占需治理矿山面积的50.8%;一般区除分布在西南部(位于房山区内)外,在中部(位于昌平、平谷、怀柔、顺义和密云县内)也有大面积分布,占需治理矿山面积的41.5%;较好区在西北(位于怀柔区和延庆县内)、西南(位于房山区内)和中部(位于怀柔南部和平谷西部)均有分布,占需治理矿山面积的7.8%。导致矿山地质环境较差区形成的主要成因指标有矿山未治理面积小和岩土体工程地质条件差;主要结果表现指标有占用破坏土地面积大和危害与损失情况严重。

| Abstract: | Based on Geographical Information System(GIS), weighting comprehensive index method is used to integrately assessment the geological environment of Beijing mines, as well as their origin mechanism. In the study area, the mine geological environment in Beijing presents unbalanced spatial distribution characteristics, the southwestern area (in Mentougou and Fangshan districts) and northern area ( in Miyun and Huairou districts) are the worse geological environment, accounting for 50.8% of requiring governing mine areas; besides southwestern areas (in Fangshan district), the central areas ( in Changping, Pinggu, Huairou, Shunyi and Miyun districts) are the moderate region, accounting for 41.5%; northwestern areas ( in Huairou and Yanqing districts), southwestern areas (in Fangshan district) and central parts (in Huairou southern part and Pinggu western part) are the better geological environment region, accounting for 7.8%. Major factors resulting in the worse geological environment of mines are not governed effectively and the engineering geological condition of rocks and soils are poor; it shows that the occupied and destroyed mine areas are larger, and the harm and loss are serious. |
