基于数值模型的地下水污染预警方法研究

地下水是中国许多城市主要的供水水源,目前中国部分城市地下水已受到不同程度的污染,导致地下水资源供需矛盾日益突出。进行地下水污染预警是保护地下水资源的一个有效措施,当前国内外相关研究刚刚起步,有关预警理论、方法和技术框架仍未形成一套完善的体系。本文简述了地下水污染预警的研究现状及存在的不足,并以中国北方某铬渣场地为例,根据当地的水文地质条件,利用数学模型建立了地下水污染预警模型,给出了不同等级的地下水污染预警分区,研究结果可为当地地下水污染防治和地下水污染控制规划提供科学依据。

A study of the groundwater pollution early-warning method based on numerical model

Groundwater is the main source of water supply in many cities of China,and it has been polluted in different degrees,leading to intense contradiction between the supply and the demand of groundwater resources.Research on the groundwater pollution early-warning method plays an important role in the protection of groundwater resources.At present,the early-warning of groundwater in research methodology at home and abroad is still at the exploratory stage,and the sophisticated warning system has not been developed.The research status and problems of the early-warning method of groundwater pollution were analyzed in this paper,the groundwater pollution early-warning method based on a numerical model was studied in a chromium residue site in northern China,and different early-warning grades were zoned by the model.The result of the study provides scientific basis for regional groundwater pollution prevention and control planning.
