基于指数和法的气矿临时用地复垦适宜性评价研究

RESEARCH ON SUITABILITY EVALUATION OF THE GAS TEMPORARY LAND BASED ON THE INDEX METHOD

建立了指数和法的适宜性评价体系,选取地形坡度、有效层厚度、灌排条件、地表物质、土地利用兼容程度、区位条件和损毁程度7个评价因子,对气矿临时用地复垦适宜性进行评价。研究结果表明:废水岩屑池为勉强适宜和中度适宜,设施基础均属于中度适宜,井场井架基础外用地属于高度适宜。并通过Paired-Samples T-Test检验和修正适宜性评价结果,为科学管理、合理利用与规划土地提供依据。

This paper established the suitability evaluation index method,and seven evaluation factors were selected including terrain slope,effective thickness,irrigation and drainage conditions,surface material,land use compatibility degree,location and extent of the damage,to assess land reclamation suitability of the gas temporary land.The results show that the area of the waste water pool belonged to appropriate and moderate suitability,the area of infrastructure belonged to moderate suitability,the others belonged to high suitability.Later Paired- Samples T- Test was used to test and modify the result of the suitability evaluation,which can provide the basis for scientific management,rational using and planning of land.
