| 摘 要： | 地下水污染问题已成为人们关注的中心问题，为从简单，适用的角度来预测各种人类活动对地下造成的污染影响，本文在水平衡及物料平衡基础下，利用概念性模型，预测在大同市近几十年的地下污染情况。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水漏斗，污水灌溉以及有些地区不允许已使用过的地下水出境等。

| Abstract: | There is increasing concern about groundwater pollution that results from a variety of human activities,including land application of wast water or fertilizers and excess draft. A simp1e and appropriate approach for predicting the effects of groundwater pollution due to the activities mentioned above is of profound realistic significance. Water and material balances have been used to create a conceptual model, with which the concentrations of chloride and nitrates in groundwater could be predicted. Thus, it is possible to predict the situation of groundwater in urban area of Datong, Shanxi, 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. |
