摘要
本文利用描述性统计分析、主成分分析和聚类分析,研究了马鞍山地区浅层地下水中19种水化学指标数据的离散性、指标间的相关性。结果表明:TDS、Fe、Mn、F-、NO-2可作为该地区人为活动对地下水影响的表征指标。对上述五种指标的综合分析显示,马鞍山地区地下水受人为活动的影响程度可分为三个区:西北区以马鞍山主城区及郊区为代表,主城区地下水受人为活动的影响程度大,郊区地下水受人为活动的影响程度较大;东南区地下水受人为活动影响程度中等;西南区及丹阳、新市镇和薛津镇一带地下水受到人为活动影响程度小。
This paper studies the dispersion and correlation of 19 hydrochemical indexes for shallow groundwater of Ma＇ anshan city, using descriptive statistics analysis, principal component analysis and cluster analysis. Results show that the TDS （total dissolved solids）, Fe, Mn, F- and NOi can be taken as characteristic indexes for human activities influenced upon groundwater. The comprehensive analysis of five characteristic indexes shows that, according to the degree of influence on groundwater by human activ- ities, the area of Ma＇anshan city may be divided into three regions： the northwest region is represented by principle city proper and suburbs of Ma＇anshan city, and the degree of influence upon groundwater by hu- man activities is great in the principle city proper and is comparatively great in the suburbs, the degree of influence upon groundwater by human activities is medium in the southeast region and is slight in the southwest region, Danyang city, Xinshi and Xuezhen town.
