摘要
根据济宁市现有的水质监测站点的监测资料,应用聚类分析方法对济宁市水质状况进行分析评价。首先利用统计软件SPSS对所选取的监测站点进行聚合分类;其次用综合指数评价法对监测站点水质划分级别;最后综合聚类结果及综合指数划级的结果将济宁市各监测站点分为六大类。在区域水环境评价中应用聚类分析法对监测站点分类,符合不同特性污染源地域分布的实际,避免单一运用综合指数法产生的缺陷。
According to the existing water quality monitoring data from monitoring sites in Jining city, the clustering analysis method is employed to analyze and evaluate the water quality of Jining city. First of all, by using the statistical software SPSS, we aggregate and classify these monitoring sites; then, the composite index is applied in evaluating the water quality of these monitoring sites; at last, the water quality of Jining is divided into six categories by the clustering results and the comprehensive evaluation combined together. In the regional water environment evaluation, monitoring sites are clas- sified by using clustering method conforms to the distribution actual of different pollution sources, which avoids the defect caused by only using the comprehensive index method.
