摘要:

植被恢复是废弃矿区生态恢复最有效的方法之一。地表沉陷导致的淹水胁迫会对修复区域内的植被正常生长产生重要影响,进而会影响整个矿区的生态恢复效果。本文基于面向对象的图像分类方法,利用WorldView-3高分辨率影像、GPS数据和实地调查数据,提取了大通废弃矿区内地表渗水面积和生态修复林地受淹水胁迫的灾情信息。根据灾情信息提取结果,矿区内受灾植被总面积为31 570 m2。其中,受淹水胁迫影响最大的树种是响叶杨,其受灾面积为11 930 m2,占受灾总面积的37.8%。研究成果可为废弃煤矿生态环境监测及生态恢复效果评估工作提供参考。

Abstract:

Restoration is one of the most effective methods for ecological restoration in abandoned mining area.The flooding stress caused by surface subsidence will have an important impact on the normal growth of vegetation in the mining area,and then will affect the ecological restoration effect of the whole mining area.In order to obtain the information of waterlogging region and ecological restoration forest which have been affected by the waterlogging stress in the Datong abandoned mining area,the waterlogging area,and the tree species of restoration forest as well as the area are extracted using WorldView-3 combining with field surveying data.The results indicated that the total affected area is 31 570 m2.The affected area of the Populus adenopoda is 11 930 m2,accounting for 37.8% of the total affected area.According to the field verification,all the Populus adenopoda are damaged by flooding stress in the surface seepage area.The research result could provide reference for the eco-environment monitoring work in the abandoned coal mine.

Key words: disaster monitoring, waterlogging stress, ecological restoration forest, WorldView-3, surface seepage
