摘要
多次采集太湖水源水以及入湖河流水样,利用三维荧光光谱手段探究荧光特征,并采用荧光区域积分法(EEM-FRI)结合主成分分析法(PCA)研究了太湖水源水CDOM的主要来源。结果表明:西氿水源水CDOM受外源的影响较大;马山水源水CDOM冬春受外源的影响较大,夏秋以内源释放为主;其余太湖水源地原水中CDOM以内源为主。
The fluorescence characteristics of raw water from Taihu Lake and into-lake rivers in different seasons were studied by three-dimensional fluorescence spectrum.Main sources of CDOM in Taihu Lake raw water were investigated by EEM-FRI and PCA.Results showed CDOM of Xijiu water source was greatly affected by external sources.In winter and spring,CDOM of Mashan water source was greatly affected by external sources,but in summer and autumn,the release of CDOM was mainly endogenous.In the other Taihu water source,CDOM was also mainly endogenous.
