| 摘 要： | 城市湖泊生态环境需水量包括:城市湖泊蒸发需水量、城市湖泊自身存在的需水量、生物栖息地的需水量、城市湖泊净化需水量、湖泊渗漏需水量、景观、娱乐需水量。需水量计算在遵循生态优先原则、兼容性原则、最大值原则和等级制原则的基础上,还应充分考虑时间性原则。计算了北京市六海各季节(冬季除外)生态环境需水量,结果表明:北京六海春、夏、秋及全年的最小生态环境需水量分别为:296.82、643.94、474.59和1415.35万m3,其中净化需水量分别占35 87%、71 23%、70 08%和63 42%。根据研究和计算结果,对改善六海生态环境提出了建议。

| Abstract: | The eco-environmental water demand of urban lake include the water for evaporation,itself,habitat,pollutant cleaning,leakage and landscape.Apart from the calculation principles of the priority to protect environment,compat ibility,max and grade,and that timelines should be emphasized.A case study of six lakes of Beijing six lakes is mentioned,and its water demand but winter is calculated.The result is that the minimum water demand in spring is 296.82×104 m3,in summer is 643.94×104 m3,and in fall is 474.59×104 m3,and the all year water demand is 1415.35×104 m3.The percentages of the water demand for pollutant cleaning are 35.87%,71.23%,70.08% and 63.42% separately According to the result,some suggestions about the development of the eco-environment of six lakes are presented. |
