| 摘 要： | 华北平原是我国的重要经济区,人口近1.3亿,地下水是其主要供水水源。在工业和生活污染物排放及农业施用化肥农药的影响下,地下水已遭受一定程度的污染。综合分析了地下水污染评价的各种方法后,将单因子污染指数法进行了改进,提出了单指标污染标准指数法。在华北平原开展了野外调查,采集了6 063组地下水样品,每个样品检测34项指标。采用单因子污染标准指数法对华北平原地下水污染状况进行了评价。结果表明:华北平原35.47%采样点的地下水已受到不同程度污染,以轻污染为主,深层地下水也有一定的污染,但比浅层地下水轻,未受污染的深层地下水占87.14%。单因子污染标准指数法基本解决了区域污染评价指标之间对比问题,能够直接反映区域地下水污染情况,并为有针对性地治理地下水污染提供了依据。

| Abstract: | The North China Plain is one of the important economic zones of China,with a population of 0.13 billion,and its main water source is groundwater.The groundwater has been polluted due to the sewage from industry and town living and the chemical fertilizer and pesticide from agriculture.The authors first analyzed several methods of groundwater contamination assessment and put forth a new method called Single Factor Standard Index Method which is obtained on the basis of Single Factor Index Method.Field investigation was conducted comprehensively.6 063 groups of groundwater samples were got and 34 factors were tested of each group.According to the Single Factor Standard Index Method,35.47% samples have been contaminated by human activities,mainly slightly contamination.Deep groundwater is better than shallow groundwater and uncontaminated deep groundwater accounts for 87.14%.Using the Single Factor Standard Index Method,the indexes can be compared and the contamination degree can be showed directly.The results of using Single Factor Standard Index Method give a basis for groundwater contamination prevention. |
