永城市陈四楼煤矿土地复垦适宜性评价研究

为了采取指数和法和极限条件法对陈四楼煤矿土地复垦适宜性进行评价。以GIS软件为平台，利用河南省永城市土壤图、地形图、土地利用现状图进行空间叠加分析最终确定4个评价单元。依据研究区的自然、经济、社会现状和相关技术标准，确定了宜农、宜林、宜渔3个复垦方向的评价指标，然后采用指数和法和极限条件法对矿区复垦土地进行适宜性评价。结果表明：评价总面积为73.7 hm2，其中适宜农业种植用地面积为25 hm2，适宜林业种植用地面积为20 hm2，适宜渔业养殖用地面积为28.7 hm2。通过评价研究建立矿区土地复垦适宜性评价等级体系。

Research on Suitability Evaluation of Land Reclamation of the Chensilou Coal Mine inYongcheng

In order to evaluate the suitability evaluation of land reclamation of the Chensilou coal mining for taking the index method and limit condition method. The study finally determined four evaluation units making use of the soil map and the current land used map and GIS software platform. According to the study area's natural, economic and social current situation and related technical standards, the paper identified the indicators of the reclamation direction of agricultural, forest, fishery. Then it was evaluated to the recalmation land of mining areas for taking the index method and limit condition method. The results suggested that, the total area of 73.7 hm2 could be divided into three parts, the area of suitable agricultural was 25 hm2, the area of suitable forest was 20 hm2, the area of suitable forest was 28.7 hm2. The study established the suitability evaluation system of land reclamation.
