| 摘 要： | 对因子分析方法在天然水体水质评价中的应用进行研究,证明在数据较为缺乏的情况下,使用因子分析方法可以损失较少信息,减少评价指标,针对主因子进行分析,使水质评价结果更为合理和有效。同时,利用因子的得分值还可以将不同地区进行比较分析。应用因子分析对河网地区典型河流的水质状况进行分析,发现了增长潜力较大的主要因子,并对该地区的水质状况做出了符合实际的总体评价,表明因子分析在水质评价中具有重要应用价值。

| Abstract: | The paper studied on the application of factor analysis in assessing the water quality of river. The research shows that the method of factor analysis can reduce the dimensions of problem with the least information lost. Using main factors to analyze water quality can make the result of evaluation more reasonable and valid. The factor score can help to compare the water quality of different areas. The paper also applied factor analysis to analyze water quality of typical river in the selected area and discovered the potential factors that would increase quickly. Assessing the water quality of the area, it was showed that the factor analysis is useful and available in the evaluation of natural water quality. |
