摘要
植被恢复是煤矿区矸石山生态修复的关键和难点。针对阳泉煤矿区覆土0.7 m以上的煤矸石山,通过野外调查和样地撒播试验,对覆土煤矸石山植被恢复的情况进行了研究。结果表明:煤矸石山覆土后植被可以较快恢复,紫花苜蓿、沙打旺、刺槐等是阳泉地区煤矸石山植被恢复初期的适宜物种。
Vegetation restoration was the most important and difficult task in ecological restoration of the coal gangue dump.In this research,field survey and planting experiment was used to study the vegetation restoration of coal gangue dump in Yangquan coal mining area,which was at least covered by 0.7 m soil.The results showed that vegetation could recover quickly on the coal gangue dump covered with soil.Vegetation species such as Medicago sativa,Astragalus adsurgens,Robinia pseudoacacia and so on were suitable for restoring the coal gangue dumps with support of soil covering in Yangquan area.
