摘　　要：在探讨城市人工湖生态环境需水特点的基础上,采用功能法分析其系统不同健康状况下的生态环境需水量,并与水量平衡法相结合,分析其相应的生态环境需补水量.同时基于长系列历史资料及生态系统现状,对天津市梅江景观人工湖进行了实例分析,研究表明,在配置水资源时,应在考虑系统功能及当地综合供水能力的基础上对生态环境需水量、需补水量进行设定.On the basis of inquiring into the characteristics of ecological-environmental water requirements （EEWR） of urban artificial lake, the calculation method of EEWR for urban artificial lake is put forward. Considering the urban lake ecosystems are in different status of health, it＇s suggested that the function method is suitable for the calculation of EEWR, and the combination of function method and water quantity balance method is rational as the calculating method for the deficit of the EEWR. Basing on long-series of history data and present situation of ecosystems, a case study of Meijiang artificial lake of Tianjin was carried out. The research showed that further progress of the estimation of EEWR and the additional water amount for the water resources distribution should consider the system function and the local comprehensive water supply ability.
