为了对湖南耒阳石界煤矿矿区进行生态恢复,首先对矿区约1.05 km2开采区域进行了实地调查分析,并运用矿山模糊综合评价方法对矿山地质环境影响进行评估.调查结果表明,矿区土壤pH值约为6.0且约0.35 km2矿区土壤结构严重破坏.采用城市污泥作为矿区土壤改良剂和肥料,并利用当地优势植物进行矿区生态恢复.实践表明,城市污泥不仅可以改良矿区的土壤特性,还可以增强矿区土壤的保水性能并能促进植物生长.综合城市污泥对土壤环境及植物生长状况的改良情况,结果表明在矿区土壤进行污泥堆肥的基础上进行混合植株种植较单植有更显著的土壤改良效果.

In order to carry on the ecology restoration to the Hunan Leiyang Shi jie coal mine mining area, a field investigation and analysis was carried out on approximately1.05 km2 mining region, and fuzzy comprehensive evaluation method was utilized to assess the impact on geological environment in mines. The survey results demonstrated approxi- mately 0.35 km2 mine soil structure was severely damaged at pH of 6.0. Municipal sewage sludge as a soil amendment and fertilizer and local advantages of plants were used for min- ing area ecological restoration. The results showed that municipal sewage sludg...
