| 摘 要： | 本文提出了一套基于ArcGIS平台的区域地下水水质评价方法,实现了单因子指标质量评价和多因子综合质量评价。方法不仅能够批量处理地下水水样和地下水质量评价结果的网格化成图,并且保留了以往容易被忽略的水质"极差点"。最后应用该方法对来自于北京市平原区1 035眼水井中的丰、枯水期近3 000余个水质数据进行了评价,结果表明平原区单因子超标的主要有总硬度、溶解性总固体、锰、氨氮、铁、氟、硝酸盐、亚硝酸盐。北京平原区地下水由浅层到中层再到深层,水质越来越好,其超III类水的面积分别为3 649 km2、2 258 km2和737 km2。区域评价结果表明,平原区地下水丰水期的水质普遍略差于其枯水期水质。

| Abstract: | In this paper,the current status of groundwater quality study in China is reviewed briefly firstly.In view of the disadvantages of traditional methods,a set of means for regional groundwater evaluation based on Arcgis system,which can not only process mass samples but also map the assessment results automatically,is put forward.The outputs of this method preserve the very poor point which was likely to be overlooked in the past.The evaluation results based on more than 3000 groundwater samples collected from 1035 wells in Beijing Plain show that from the shallow part to the depth,the quality of groundwater in Beijing tends to become better.The analytical results show that the main excessive components of the groundwater samples are total hardness,TDS,Mn,NH-4,Fe,F-,NO-3 and NO-2.The total area belonging to class IV and V is 3649 km2,2258 km2 and 737 km2 respectively for shallow,middle and deep groundwater.Also,the comparative results show that on the whole the groundwater quality in the wet period is slightly worse than that in the dry period within Beijing Plain. |
