关闭矿山生态修复植物选择与施工技术

矿山的过度开采会加速水土流失、降低植被存活率，导致矿山区域生态环境变差，急需进行矿山区域生态环境修复。提出了关闭矿山生态修复植被选择与施工技术，分析矿山区域的地层岩性及水文地质，获取土壤有机物质的性质指标，分析了土壤物质的总体含量会对生态环境修复效果的影响。根据分析结果，选取不同种类的植物指进行调查、筛选测试，得到适应力强、成活率高、覆盖率广的植被，实现生态修复植物的选择。以修复植物选取结果为基础，对矿区的道路、边坡、生产环境等进行治理防护，完成关闭矿山生态修复植物的选择与施工技术研究，改善了矿区生态环境。

Plant selection and construction technology for ecological restoration of closed mines

Overexploitation of the mine could accelerate water and soil loss，reduce the survival rate of vegetation，and lead to the deterioration of the ecological environment in the mine area. Therefore，it was urgent to repair the ecological environment in the mine area. It was proposed to close the selection and construction technology of vegetation for ecological restoration in the mine. This paper analyzed the stratum lithology and hydrogeology of the mine area，obtained the property index of soil organic matter，and analyzed the impact of the overall content of soil matter on the ecological environment restoration effect. According to the analysis results，different kinds of plant fingers were selected for investigation，screening and testing to obtain vegetation with strong adaptability，high survival rate and wide coverage，so as to realize the selection of ecological restoration plants. Based on the selection results of restoration plants，construction treatment and protection shall be carried out for the roads，slopes and production environment in the mining area，and finally the selection of ecological restoration plants in closed mines and the research on construction technology shall be completed，so as to achieve the purpose of improving the ecological environment in the mining area.
