摘　　要：研究区作为河南重要的能源化工基地,近年来地下水水环境地质问题突出,制约着当地的社会经济可持续发展。文章在分析研究区水文地质条、水质分析的基础上,选取含水层埋深、隔水层岩性、隔水层的连续性、隔水层厚度等指标,建立了“DLCT”模型作为评价体系,对研究区中深层地下水进行防污性能评价。根据分区结果划分出防污性能很好、防污性好和防污性中等区,其中防污性能很好区域面积约267.37 km^(2),防污性能好区域面积约53.13 km^(2),防污性中等区域面积约2488.19 km2,针对上述分区提出了相应的保护措施和建议,进而为当地地下水资源科学保护和可持续利用提供参考依据。As an important energy and chemical industry base in Henan Province,the research area has prominent groundwater environmental geological problems in recent years,which restricts the sustainable development of local society and economy.Based on the analysis of hydrogeology conditions and water quality in the study area,the"DLCT"model is established as the evaluation system to evaluate the anti-pollution performance of the middle and deep groundwater in the study area by selecting the buried depth of aquifer,the lithology of aquiclude,the continuity of aquiclude and the thickness of aquiclude.According to the results of zoning,the areas with good pollution prevention performance,good pollution prevention performance and medium pollution prevention performance were divided.The area with good pollution prevention performance was about 267.37 km^(2),the area with good pollution prevention performance was about 53.13 km^(2),and the area with medium pollution prevention performance was about 2,488.19 km.Corresponding protective measures and suggestions were put forward for the above zoning.It provides reference for scientific protection and sustainable utilization of local groundwaterresources.
