摘要
根据金泉工业园水源地8个不同监测断面的地下水水质监测数据,采用R型因子分析法对园区水源地地下水水质进行综合评价,在研究地下水中13种化学成分间相关关系的基础上,提取4个主因子进行分析计算。结果表明,Cl-、SO24-、总硬度和可溶性固体对第一主因子贡献明显;第二主因子代表指标是Zn;第三主因子代表指标是As;NO3-、氨氮、NO2-对第四主因子贡献显著。对水质进行综合评价后发现,人民渠、海流图河和乌拉壕监测断面处水质类别为V类,其他断面均为IV类。因子分析法从整体上评价了园区水源地地下水的水质现状,分析结果清晰明确,为日后地下水资源的管理与保护提供科学依据。
Under the 8 different monitoring sections of the groundwater quality monitoring data that Jinquan Industrial Area water source,using R-factor analysis of the water area a comprehensive evaluation of groundwater quality,based on 13 species that the correlation between the chemical composition are studied in groundwater,then four kinds of main factor are extracted,and analysis calculation.The results show that,Cl-,SO2-4,total hardness and soluble solids on the first principal factor contributed significantly;the second factor is the representative indicator of Zn;The third factor is As;NO-3,ammonia,NO-2 on the fourth factor contribution significant.People channel,Current River and the Ural trench Map Department water quality monitoring sections,that in the worst water quality class for the V class,other sections are Class IV.Factor analysis to evaluate the whole industrial park water quality of groundwater,the results is clear,the future for the park management and protection of groundwater resources to provide a scientific basis.
