| 摘 要： | 为研究沈阳市李官堡傍河水源地的水化学变化特征与污染来源,在对该水源地开展野外污染调查、水化学样品采集等工作的基础上,结合聚类分析和因子分析两种多元统计分析方法对研究区地下水环境进行系统分析。结果表明:研究区平水期和丰水期的地下水均可划分为Ⅰ、Ⅱ两类具有不同水化学特征的两个区域。Ⅰ区主要分布在浑河沿岸,主要特征为Eh值偏低,pH值偏高,处于还原环境中,NH4+污染主要来源于浑河下渗与农业活动;Ⅱ区主要分布在研究区西北部,主要特征为Eh值偏高,pH值偏低,处于氧化环境中,NO3-污染主要来源于居民日常生活和工业活动等地表污染的垂向入渗。

| Abstract: | This paper aimed at investigating the hydrochemical characteristics and pollution sources of the groundwater in Liguanpu Riparian Wellhead area,on the basis of a field pollution sources investigation and a series of hydrochemical sampling campaigns,with multivariate statistical methods of cluster analysis and factor analysis.A systemic study in respect of the environment of groundwater in the area was conducted depending on these work.The results indicated the groundwater of moderate season and wet season in the area could be divided into two regions which had different hydrochemical characteristics.Zone Ⅰ principally spread along the Hun river,whose characteristics were the lower Eh values,the higher pH values,in the reducing environment,owning the serious ammonia nitrogen pollution which was principally derived from the Hun river and agricultural activities.Zone Ⅱ was mainly distributed in the northwest of the area,whose characteristics were the higher Eh values,the lower pH values,in the oxidation environment,owning the serious nitrate pollution which mainly originated from the vertical infiltration of surface pollution sources such as the daily life of residents and industrial activities. |
