露天煤矿排土场无法覆土区域生态恢复重建技术

Ecological restoration and reconstruction technology in open-pit coal mine dump uncovered soil area

为解决露天煤矿排土场无法覆土条件下的生态恢复问题,提出建立稳定的人工重建生态系统的方式方法,基于工程实施实际,结合施工后植被和土壤状况的调查和分析,对该立地条件下生态恢复重建方式进行可行性论证,提出了可行技术。结果表明:在排土场无法覆土条件下,选用当地适生植物先行培育,再进行坡面栽植,采取必要的人工诱导扶持措施,进行有效地控制和管理,恢复重建生态是经济的、可行的。

In order to solve the problem of ecological restoration under the condition that the dump of open-pit coal mine cannot be covered with soil,the article puts forward the methods of establishing stable artificial reconstruction ecosystem.Based on the practice of project implementation,combined with the investigation and analysis of vegetation and soil conditions after construction,the article demonstrates the feasibility of ecological restoration and reconstruction under the site conditions,and puts forward the feasible technology.The results show that:under the condition that the dump cannot be covered with soil,we select local suitable plants to cultivate first and then plant on the slope,take necessary artificial guidance support measures to effectively control and manage.It is economic and feasible to restore and rebuild the ecology.
