黄河河南悬河段地下水环境健康评价

根据水环境健康理论,探讨了地下水环境健康的概念,构建了包括目标层、准则层、指标层的地下水环境健康评价指标体系结构。根据指标层19个因子,建立了地下水环境健康评价标准。选取7个评价指标,采用灰色聚类法评价了黄河下游悬河段郑州、开封、新乡、濮阳4个地区的地下水环境健康状态。结果显示,郑州、濮阳地区地下水环境处于不健康状态,新乡、开封地区处于亚健康状态。

Evaluation on Environmental Health of Groundwater in Henan Elevated River Section of the Yellow River

The paper approaches the concept of environmental health of groundwater and builds an evaluation index system structure of water environmental health including target strata,criterion strata and index strata based on the theory of water environmental health.It establishes indexes for evaluating the environmental health of groundwater based on 19 factors of index strata.It appraises the status of environmental health of groundwater of 4 regions of Zhengzhou,Kaifeng,Xinxiang and Puyang located on the elevated section of the lower Yellow River through selecting 7 indexes by using gray cluster method.The outcomes show that the groundwater environment of Zhengzhou and Puyang are in unhealthy status and Xinxiang and Kaifeng in subhealth.
