【摘要】 为查明哈尔滨地区浅层地下水水质现状及污染情况,利用松嫩平原(黑龙江)地下水污染调查评价项目的数据,对浅层地下水主要化学特征进行了描述.在此基础上采用模糊综合评价法进行了地下水质量评价,采用污染指数法进行了地下水污染现状评价.结果表明:研究区浅层地下水水化学类型以HCO3-Ca型为主;受原生环境下水化学条件控制的Fe、Mn指标含量对水质影响较大;地下水污染属于区域性污染,污染范围广、污染程度重,主要污染物为NH4+及NO-3、NO2-,来源于生活污水及农业生产所施用的化肥.根据分析数据,研究区地下水污染以无机污染为特征.更多还原

【Abstract】 With the groundwater quality monitoring data of Songnen Plain in Heilongjiang Province, the chemical characteristics are described to ascertain the current situation of quality and pollution of the shallow groundwater in Harbin region. On this basis, fuzzy comprehensive evaluation method is used to assess groundwater quality. The current status of groundwater pollution is assessed by pollution index method. The results show that the hydrochemistry of the shallow groundwater is dominated by HCO3-Ca type. The Fe and Mn contents, which are controlled by the hydrochemical condition in native environment, strongly impact the water quality. The groundwater is regionally polluted, with wide range and severe degree. The main contaminants are NO-3, NO2-and NH4+, which are derived from domestic sewage and fertilizers in agricultural production. According to the data analysis, the groundwater pollution in the study area is mainly inorganic pollution.更多还原
