地下水污染指示性因子指标体系构建

CONSTRUCTION OF INDICATOR SYSTEM OF GROUNDWATER POLLUTION

地下水是京津冀地区重要饮用水源,由于地下水资源不合理的开发利用和污染物排放,京津冀地区地下水受到不同程度的污染,严重威胁当地居民饮水安全,地下水污染预警和防治成为重点关注的环境问题之一。本文从预警和污物防控的角度,厘定了地下水污染指示性因子概念和内涵,提出了区域尺度地下水污染指示性因子指标体系的构建原则、方法和指标体系,从指示地下水地球化学环境、水质演化、地下水污染类型、污染源等4个方面选取了30个典型指标构建了地下水污染指示性因子指标体系,对关键评价指标的意义进行了具体分析。

groundwater is an important source of drinking water in the beijing-tianjin-hebei region. Due to the unreasonable development and utilization of groundwater resources and pollutant discharge, the groundwater in the beijing-tianjin-hebei region is polluted to varying degrees, seriously threatening the drinking water safety of local residents. The early warning and prevention of groundwater pollution have become one of the key environmental issues.From the Angle of the early warning and contamination control, define the concept of groundwater pollution indicative factor and the connotation, puts forward the regional scale groundwater pollution indicative factor index system construction principles, methods and index system, and instructions from the groundwater geochemical environment, the types of groundwater pollution, pollution source, pollution from four aspects, such as 30 typical indicative constructed groundwater pollution index factor index system, gives a detailed analysis of the meaning of key evaluation index.
