摘要
以洪湖为例,从生态调水的角度出发,向湖体输入改善水质的生态环境用水,并根据物质守恒原理建立湖泊水质模型,对生态环境用水量进行了估算,得出在年入湖污染物质排放总量不变的条件下,满足洪湖TN浓度达到Ⅲ类标准(TN=1.0 mg/L)所需的生态环境用水量为23.2×108m3/a.
In this paper, eco-environmental water use for Honghu Lake is studyed from the ecological water dispatching point of view. This paper calculated volume of eco-environmental water use with water quality models based on mass conservation principle. The result is that eco-environmental water use of Honghu Lake is 23.2 ×10^8m^3/a when the TN concentration meets Ⅲ Class Environmental Quality Standard for Surface Water, based on the assumption that total imported pollutants keeps constant.
