摘　　要：通过１９９２～１９９３年对千岛湖水质、底质、生物和污染源的调查，对其水环境质量和污染物输入作了综合的评价。结果表明：千岛湖水质状况良好，但局部水域水质污染逐年加重，湖泊已属中营养状态。非点源输入量占入湖污染总量的９５％，而５０％非点源输入量来自上游安徽来水。建立了对流扩散模型并进行水质预测，提出了千岛湖水环境保护对策。On the basis of investigation from 1992 to 1993 on water quality, sediment, biology and pollution sources of the Qiandao Lake, the status of water environmental quality in the lake and total input of pollutants into the lake were comprehensively assessed. The results indicate that the water quality of the lake remains well, while pollution in some local waterbody increases with years and the trophic status tends to become mesotrophic level; non-point-source pollution load, 50% of which are inputted from the upstream rivers of Anhui Province, covers 95% of the total input load into the lake. A convection diffusion model of water quality were established and the water quality was predicted, and the countermeasures of water quality protectiion in the Qiandao Lake was suggested.
