| 摘 要： | 通过１９９２￣１９９３年千岛湖水质、底质、生物和污染源调查，对其水环境质量和污染物输入作了综合评价。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％，其中５０％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。

| Abstract: | On the basis of investigation from 1992 to 1993 on water quality, sediment, biology and pollution sources of Qiandao Lake, the status of water environmental quality in Qiandao Lake and total input of pollutants into the lake were comprehensively assessed. The result indicates that the water quality in Qiandao Lake remains well, while the water quality pollution in local region increases with years and trophic status tends to become mesotrophic. 50% of non-point pollution load, equivalent to 95 % of total input of pollutants into the lake, were derived from the upper rivers of Anhui Province. A convection diffusion model of water quality was established and the water quality was predicated. Some protection countermeasures of water env-iornmental quality in Qiandao Lake were suggested. |
