摘要
通过系统对比20世纪60年代以来北京市平原区地下水监测资料,确定了以特征污染物:总硬度、溶解性总固体和硝酸盐氮等为分析对象,探讨了3种特征组分多年来的变化规律,并结合水文地质条件、岩性结构、地下水开采及工农业生产等方面,研究了3种特征组分分布及成因。
Total hardness, TDS and NO3-N were taken as the objects of this research because they were typical pollutants in the groundwater of plain area of Beijing. Here distribution and concentration of these pollutants were analyzed with reference to documents of groundwater monitoring in this plain since 1960s. Meanwhile the influence factors of their distribution were studied, which involved factors such as hydrological condition, groundwater discharge and different producing structures.
