地下水污染趋势预测研究

在水量平衡及物料平衡的基础上，利用概念性模型，预测了山西省大同市近几十年的地下水污染情况，并结合模型结果，讨论了地下水恶化的主要原因是地下水超采形成降落漏斗、污水灌溉，以及有些地区不允许已使用过的地下水出境等。本文的研究可为地下水水质保护工作提供科学依据。

The Study on Groundwater Pollution Predication

Water and material balances,a conceptual model is employed to predict the situation of groundwater in urban area of Datong, Shanxi province,over a thirty-year period. With the simulation results,the main cause of groundwater deterioration can be attributed to the formation of drawdown cone due to excess draft,excess sewage irrigation and erroneous zero-outflow policy for groundwater.The concept proposed and its results may serve as scientifically based on evidence for those who are recognizing the nature of the problem of groundwater pollution,and are working to protect their local groundwater quality.
