城市生态环境需水量计算方法与应用
Calculation Method for Urban Eco-environment Water Demand and Its Application
摘要
Abstract
This paper firstly summarizes and analyzes the connotation and characteristics and type of urban water demand of eco-environment;on this basis,proposing urban eco-environment water demand including urban rivers and lakes and green spaces and wetlands and then combined with the water quality and water quantity model to achieve quality and quantity of water unity.Taking Changshu city for example,the eco-environment water demand and water quantity and water quality model is calculated and established.The results show that the eco-environment water demand which takes for consumption or replacement for rivers and lakes evaporation,lakes water exchanging,green space evapotranspiration in Changshu city is totally about 6.575 million m3;Water quantity and water quality model of Changshu city shows that the improve-ment rate of CODMnand NH3-N in urban river are 66.7% and 64.5% respectively after the city comprehensive cutting pollution;at 20 m3/s,30 m3/s,40 m3/s of external water flow,the improvement degrees of CODMn are 30.3%,35.1% and 42% respectively;the improvement degrees of NH3-N are 19.7%,28%,36.7% respectively.关键词
