干旱草原区露天煤矿环境影响后评价探讨

Environment Impact Post-assessment for Open-pit Coal Mine in Arid Grassland

为评价干旱草原区露天煤矿生态环境影响范围和程度,判断生态恢复效果,在分析干旱草原区露天煤矿生态环境影响特征的基础上,提出了该区生态环境影响后评价的特点与重点。并以胜利矿区一号露天煤矿为例,采用回顾分析法、GeoEye遥感影像与QuickBird遥感数字图像解译,分别从土地利用、植被覆盖、水土侵蚀角度进行了生态环境影响后评价。

Based on the characteristics analysis of ecological environment impacts of open-pit mines in arid grassland,the emphases of post-assessment of ecological environment impacts in this area are put forward.Taking No.1 Open-pit Mine of Shengli Mining Area as an example,the retrospective analysis method,Geo Eye remote sensing image and Quick Bird remote sensing digital image interpretation are used.The post-assessment of ecological environment impact was carried out from the aspects of land use,vegetation cover and soil erosion.
