【摘要】 以内蒙古阿拉善右旗雅布赖变至阿右旗变220kV输电线路工程为例,采用MODIS-NDVI影像,分别获得了该输电线路建设前后评价范围NDVI均值,结果表明:该输电线路工程沿线NDVI呈上升趋势;历经4年的时间,线路沿线高覆盖植被显著增加,而低覆盖植被明显降低;总体上线路沿线植被覆盖以改善为主,特别是线路两端植被恢复明显。在此基础上,提出了内蒙古自治区阿拉善盟输电线路工程生态恢复的前提、时机和措施,对项目区同类工程的生态恢复提供参考。更多还原

【Abstract】 In case of "220 kV transmission project from Ya Bu Lai Substation to Alxa Right Banner Substation",the variation of vegetation coverage were analyzed based on MODIS NDVI data.The results indicated that the vegetation cover along the both sides of Power transmission project was increased; After four years, High Vegetation cover was Significant increased, lower Vegetation cover was Significant reduced, On the whole, the vegetation cover along the line is mainly improved,Especially the vegetation restoration at both ends of the line is obvious. On this basis, the premise, opportunity and measures of ecological restoration of Alashan League transmission line project in Inner Mongolia Autonomous region are put forward, which can provide reference for the ecological restoration of similar projects in the project area.更多还原
