| Abstract: |
| Based upon the monthly,obtained data on water quality from 1981 to 1990 in Poyang Lake district, the status quo and trend of water quality in Poyang Lake are comprehensively analysed.The results are: (1) BOD5 surpluses by 2.1%~22.2% in 1990 in some inlets and near some stations of the lake area;TP surpluses by 9.1%-29.3% at all stations except the esturies of the Gangjicing Rever (West Branch) and Fuhe River;(2) As,volatile phenol and TP are the main pollutants;(3) the natural conditions of the lake are not favorable for eutrophication though TP and TN exceed the limit in some areas;(4) the general assessment results show that water in the inlets of the Xinjiang River (west Branch) and Banghu and in lake areas such as Sheshan, Duchang, Zhuxihe River mouths belongs to type B, while that of the other areas belongs to type II;(5) the contents of As, COD, NH3-N, DO and BODs fluctuate from year to year, while As and COD have been inclined to an increase since 1986;(6) with the increasing inlake pollutants, the water will be aggravated gradually. |
