资源再生型地区资源环境承载能力评价指标体系构建——以河南省洛宁县为例

Establishment of the evaluation index system for resources and environment carrying capacity in resource regeneration areas:A case study of Luoning County,Henan Province

为构建资源再生型地区资源环境承载能力评价指标体系,以河南省洛宁县为例,通过开展1∶5万环境地质调查与地质环境背景资料收集,查明了该区资源环境禀赋条件和短板要素,并在地质环境承载能力、地下水资源承载能力和矿产资源承载能力评价的基础上,引入了矿山地质环境承载能力评价,创新性地构建了一套适用于资源再生型地区的资源环境承载能力评价指标体系。在完成实际验证评价的基础上,与通用资源环境承载能力评价指标体系进行了对比分析,结果发现,矿山地质环境承载能力评价结果与地质环境承载能力评价结果并不完全一致,且与矿产资源承载能力评价结果也有一定差异。研究表明,构建的资源再生型地区资源环境承载能力评价指标体系更适宜此类地区矿区分散分布且发展方式迥异的特点,能进一步突出地域主导特色,可为同类地区地质环境保护及资源开发规划提供参考。

In order to establish the evaluation index system of resources and environment carrying capacity in resource regeneration areas,the authors in this paper have carried out 1∶50000 environmental geological survey and geological environment background data collection in Luoning County of Henan Province,in order to find out the resources and environment endowment conditions and its disadvantageous elements.Based on the evaluation of geological environment,groundwater and mineral resources carrying capacity,the authors have adopted the evaluation of mine geo-environment carrying capacity to creatively construct a set of evaluation index system of resources and environment carrying capacity suitable for resource regeneration areas.On the basis of the actual verification and evaluation,through the comparison with the general evaluation index system of resources and environment carrying capacity,the authors have concluded that the mine geo-environment carrying capacity result is different from the geological environment carrying capacity result,and is also different from the mineral resource carrying capacity result.The results above show that the carrying capacity evaluation system in this paper is more suitable for resource regeneration areas with scattered mining areas and different development modes,which could further highlight the regional leading characteristics and provide some reference for geological environment protection and resource development planning in similar areas.
