摘要
土地复垦适宜性评价是土地复垦工作的基础,决定了待复垦土地的复垦方向。本研究以宜兴市张渚镇东龙村工矿废弃地复垦项目为例,确定评价单元,综合考虑自然社会条件、国家政策以及公众意愿,构建了4个自然因素指标和2个社会经济因素指标构成的露天矿山土地复垦适宜性评价指标体系,采用层次分析法确定各指标权重,以指数和法计算各评价单元评价得分,并确定各评价单元的土地复垦利用方向。该评价指标体系和评价结果可为该地区类似露天矿山土地复垦工作提供参考。
Suitability evaluation is the basis of land reclamation work,and decides the direction of reclamation. In this paper,the Donglong Village's mining wasteland project in Zhangzhu Town of Yixing City was taken as the example. After determining the evaluation unit and considering the natural and social conditions,the national policy,as well as the public will,a land reclamation suitability evaluation system was established for the abandoned open mining pit with four natural indicators and two socio- economic indicators. The analytic hierarchy process( AHP) was used to determine the index weight,and the exponential sum method was used to calculate the score of each evaluation unit,and then the direction of land reclamation was determined.This evaluation index system and its results might provide references for the land reclamation of those similar open pit mines in this region.
