摘要:
根据鄱阳湖1990年监测资料,对水质污染现状进行分析,同时利用1981-1990年资料,分析了水质变化趋势。分析表明:湖体、河口水质均属较清洁水或尚清洁水。但是,随着入湖污染负荷量的增加,湖区水体污染呈上升趋势,宜引起有关部门高度重视。

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.
