济南地区岩溶地下水污染评价及保护措施

Pollution Evaluation and Protection Countermeasures of Karst Groundwater in Ji'nan Area

摘要:

地下水是一个城市水循环的重要组成部分，地下水的质量关系到城市居民的生命健康安全。为确定济南地区地下水的污染状况，本文以历年的水文资料作为背景值，采用了单因子和多因子2种评价方法对济南地区岩溶水进行了污染程度评价，根据评价结果将研究区岩溶水污染程度进行了分级；在地下水系统防污性方面，采用DRASTIC模型对济南地区的防污程度进行了分区。结合岩溶水污染程度和防污性能两方面的评价结果，为实现可持续开采岩溶地下水，本文对地下水的开发利用和保护分别进行了分区，并给出了相应的保护措施，为济南地下水开采与保护提供可靠依据。

Abstract:

Groundwater is an important part of the urban water cycle, and the quality of groundwater is related to the life, health and safety of urban residents. In order to determine the environmental quality of groundwater in Ji'nan city, by using single factor and multifactor evaluation methods, the degree of groundwater pollution with hydrological data over the years as the background value, according to the evaluation result, the pollution degree of karst water in the study area is classified. In terms of the antipollution performance of the groundwater system, the DRASTIC model is used to analyze the degree of pollution prevention in the area. According to the results, the area is divided into different regions. Combining with the evaluation results of karst water pollution degree and antipollution performance, in order to realize the sustainable exploitation of groundwater, the exploitation and protection of groundwater have been divided respectively, and corresponding protection countermeasures have been given. It will provide reliable basis for groundwater exploitation and protection in Ji'nan city.
