基于熵权可拓物元模型的矿区生态修复区域划分研究
Research on zoning of ecological restoration in mining area based on Entropy-weighted Extension Matter-element Model:A case study of Huojitu Mine
摘要
Abstract
The accutae assessment and zoning of ecological restoration area is an important premise and foundation for ecosystem restoration and reconstruction,which is of great significance to improve the qual-ity of the ecological environment.Objectives To address the relative lack of research on ecological restora-tion zoning in mining areas,Methods In this context,this paper takes the Huojitu mine of Daliuta coal mine as the study area.An evaluation index system was constructed based on selects soil nutrients,vegeta-tion coverage,land damage degree,and topographic location index.The Entropy-weighted Extension Matter-element Model was then applied to delineate ecological restoration zones.Results The results show,(1)The selected model avoids the influence of subjective factors on the weights,and can integrate mul-tiple indicators for unified quantitative grading,providing methodological support for zoning the ecological restoration areas.(2)The disturbance areas of open-pit mines,underground mines,and urban areas in the research area covers 10.81,33.05,and 5.96 km²,respectively,accounting for 44.47%of the total area of the research area.From the perspective of internal structure,the disturbance zones are classified into three restoration types,intensive artificial intervention restoration areas,assisted artificial intervention restoration areas and natural restoration areas.Among them,intensive artificial intervention restoration areas cover 25.58 km²,accounting for 22.83%of the total area of the study area;assisted artificial intervention restora-tion areas cover 17.78 km²,accounting for 15.87%of that;natural restoraion areas cover 6.46 km²,ac-counting for 5.77%of that.(3)For different ecological restoration area types in disturbance zones,differ-ent restoration plans are presented.Natural restoration areas adopt natural greening methods;the assisted artificial intervention restoration areas adopts methods such as introducing advantageous species and precise soil fertilization;intensive artificial intervention restoration areas adopts methods such as adjusting mining layout,slope cutting and filling,and improving soil.Conclusions The results of the study can provide refer-ence for ecological restoration projects in mining areas.关键词
