基于指数和法与极限条件法的土地复垦适宜性评价研究

Study on Land Reclamation Suitability Evaluation of Coal-mine Based on Index Method and Limit Condition Method

以山东省刚屯煤矿为例,从土地利用现状、破坏程度、土壤类型、有效土层厚度、排水条件、灌溉条件等方面确定了9个评价单元,应用层次分析法确定指标权重,采用指数和与极限条件相结合的方法对研究区土地复垦适宜性进行评价,得出了土地复垦方向,并对评价结果进行了分析,从而为科学管理、合理利用与规划土地提供依据。

Taking the case of Gangtun coal-mine of Shandong Province,9 evaluation units were determined from the aspects of land utilize situation,destroyed degree,soil types,effective soil thickness,drainage conditions and irrigation conditions,etc..Using analytic hierarchy process,index weights were determined,and using the combination method of index method and limit condition method,land reclamation suitability of study areas was evaluated,the direction of land reclamation was obtained,and the results of evaluation were analyzed,thereby,those provided basis for scientific management,rational utilization and land planning.
