| 摘 要： | 依据2008-2009年11个采样点8个水质指标数据,运用主成分分析和聚类分析,对闽江水质时空分布进行探索性研究。通过统计分析将8个水质指标概括为2个主成分,在空间尺度上分为2组,重污染区和轻污染区,在时间尺度上分为2组,枯水期和丰水期。结果表明闽江上游污染较为严重,中游一直到下游污染程度呈下降趋势。经过福州市区后,由于汇入了大量的生活和生产污水造成污染,使闽江水质急剧下降。同时,闽江水质受该地区的降雨量影响较大,它亦随着水温的变化呈季节性变化,冬季的水质最差。

| Abstract: | The principal component analysis(PCA) and hierarchical cluster analysis(CA) were used to analyze data sets of water quality for 8 parameters monitored at 11 different sites of Min River from 2008 to 2009 to determine temporal and spatial distribution in water quality.Through the statistical analysis of eight water quality were indexed as two principal components,the monitoring sites were partitioned into 2 groups included heavy polluted area and light polluted area;the monitoring periods were classified int... |
