| 摘 要： | 结合2008年夏季丰水期对太湖上游直湖港、大浦河、长兜港3条河流有色可溶性有机物(CDOM)吸收和三维荧光的测定分析,探讨了夏季丰水期时河流输入对太湖中CDOM的贡献.3条河流中直湖港CDOM浓度最高,大浦河次之,长兜港最低,反映了太湖北部外源河流污染物输入大于西南部.3条河流内CDOM吸收α(355)的均值为(4.7...

| Abstract: | The spectral absorption and the three-dimensional fluorescence of chromophoric dissolved organic matter(CDOM) in three rivers(Zhihugang,Dapukou,and Changdougang) located upstream of the Taihu Lake are determined.Such an upstream contribution to CDOM in the lake during the summer rainy season of 2008 is analyzed.It is found that the Zhihugang River has the highest CDOM absorption value,and followed by Dapukou.The lowest CDOM value is found in the Changdougang River.This result indicates that the allochthonou... |
