摘　　要：以天津市梅江景观湖为例,在充分考虑当地丰枯条件的基础上,引入生态环境需水理论,对该人工湖进行了水量、水质联合优化配置。研究表明,无论湖泊蓄水等级处于不变、降低、提高等情况,人工引水量均远大于自然引水量,分别占三种情况下引水总量的84.40%、75.86%和70.69%,且湖泊水质均可达标。此外,在保证城市人工湖生态系统健康的基础上,充分利用蓄水等级降低时多余的储蓄水量及丰水年的降水,可降低一定的供水费用。同时,为了保持湖泊生态系统的稳定性,应防止蓄水等级的突变。Considering the conditions of local water resources and the theory of ecological and en- vironmental water requirements, the optimal distribution combined with water quantity and water quality for Tianjin Meijiang artificial lake was studied. The results showed that no matter the water level of Mei- jiang lake was unchanged, reduced or raised, the artificial diversion of the total water volume was much larger than that by the natural water, which accounted for 84.40%, 75.86% and 70.69%, respective- ly, and could satisfy with water quality standard. To ensure the health of the urban lake ecosystem, the total usage of the surplus-savings of water at low water level and the precipitation in wet years could re- duce the cost of water supply. Also, to keep the stability of the lake ecosystem, the mutation of water lev- el should be prevented.
