备注

土地复垦对矿区生态改善和经济发展有着重要意义。针对矿区因矿产资源开采造成的受损土地,基于神东矿区近10年土地复垦监测数据,整理了土地复垦影响因素等级标准,构建了矿区土地复垦效益评价指标体系,在此基础上,采用专家打分法和传统的评价模型,评价了神东矿区榆家梁煤矿土地复垦综合效益。结果 表明,实施土地复垦使矿区土地类型大幅改善,塌陷地、堆积占地等受损土地面积减少,耕地、建设用地等可利用土地面积增加,矿区土地复垦面积增加了63%; 同时,榆家梁煤矿的生态效益、经济效益和社会效益均有不同幅度提高,生态效益增加最为显著,增长率为56%,且根据评价等级标准,土地复垦后矿区效益分值均达到良好状态。该方法能对神东矿区土地复垦后取得的各项效益进行较准确的评价,有助于矿区生态、经济、民生协调可持续发展。

Land reclamation is of great significance to the ecological improvement and economic development of mining area.Based on the monitoring data of land reclamation in Shendong mining area in recent 10 years,this paper sorted out the grade criteria of influential factors of land reclamation and constructed the evaluation index system of land reclamation benefit in mining area.On this basis,the expert scoring method and traditional evaluation model were used to evaluatecomprehensive benefits of land reclamation in Yujialiang coal mine,Shendong mining area.The results show that the implementation of land reclamation has greatly improved the land type of mining area,reduced the area of damaged land such as subsidence land and accumulation land,increased the area of available land such as cultivated land and construction land,and increased the area of land reclamation in mining area by 63%.At the same time,the ecological,economic and social benefits of Yujialiang coal mine are also improved.The ecological benefit increasedmost significantly with a growth rate of 56%.According to the evaluation grade standard,the benefit scores of mining area after land reclamation reached a good state.This method can accurately evaluate the benefits of land reclamation in Shendong mining area,and is helpful to the coordinate and sustainable development of ecology,economy and people's livelihood in mining area.
