摘　　要：某河流是铜陵境内主要长江支流之一,流域内矿产资源丰富,金属矿山众多,矿业活动对流域地下水环境质量可能造成较大影响。本文以该流域浅层地下水为研究对象,通过系统取样分析,借助MapGIS等软件对测试结果进行空间分析,研究流域浅层地下水环境质量及污染组分分布规律。研究表明:流域浅层地下水水质总体较好,局部存在污染现象,主要超标项目有SO、pH等,重金属元素Mn超标,Fe、Cd、Pb、Ni等偶有超标,其他基本不超标。研究结果为小流域生态环境保护、矿山地质环境治理及监测预警提供了地质依据。A river is one of the main tributaries of the Yangtze River in Tongling. Within the river basin, mineral resources are abundant, mines numerous, and the mining activities may have a great impact on the quality of the groundwater environment. Focusing on the shallow groundwater in the river basin, this paper studies its environmental quality and the distribution law of the contaminants in it through systematic sampling analysis, and spatial analysis of the test results with MapGIS software. The results show that the quality of the shallow groundwater is generally good but locally contaminated in the river basin. The main items exceeding standards are SO, pH, etc. Heavy metal Mn exceeds the standard, Fe, Cd, Pb and Ni occasionally exceed the standards, others are basically normal. The research results provide a geological basis for ecological environment protection, mine geo-environment control, and monitoring and early warning for a small river basin.
