| Abstract: | According to quality monitoring data in three bays of Lake Taihu,the correlations among 7 pollutants were studied and sources of water pollutants were discussed by using factors analysis.Results showed that the first polluted factor contained TN,TP and Chla,the secondary important pollutants were NH4+-N and CODMn while the third was NO3——N in Meiliang Bay.TN,TP,CODMn and Chla composed the first main factor,while the second consisted of NH4+-N,NO3——N and SS in Gonghu Bay.While in the bay of East Taihu Lake,contributions of TN,TP,CODMn and SS were the biggest, followed by NH4+-N and Chla,NO3——N was the third contributing factor.Based on the spatial distribution of component score,the analysis of pollutant source provided an overall status of water quality and a scientific theory for protecting and managing water resource of the Lake. |
