平原区井灌对地下水水质影响评价方法研究

The Study on Evaluating Methods for Well-irrigation to Affect the Ground Water Quality on the Plain

从“开采抽取”这样一个特定条件出发,分析开采(井灌)引起地下水水质恶化的途径与机理,通过对地下水水质变化的定量预测,选取适宜的评价因子与评价标准,进行地下水水质变化趋势评价以及分级评价,是地下水环境影响评价的重要内容。

From the particular condition of exploiting and drawing, this paper analyses the way and disposition how exploiting affects the deterioration of ground water quality, singles out proper evaluating factor and standard, carries out the tendenly and grading evaluation on the change of ground water quality by calculating. It is an important part for evaluating the enviormental influence of ground water.
