摘　　要：在邛海水量平衡分析的基础上,从城市湖泊功能上对其最小生态需水量进行了研究。结果表明,邛海水量平衡计算结果为-0.344×108 m3,处于入不敷出状态;从城市湖泊功能计算,邛海的生态需水量为2.490 9×108m3,其中净化需水量占20.55%。随着人为取水继续增多,水体污染,邛海生态环境所需适宜水量将难以保障,建议管理部门采取改善措施。Ecological water has an important role to maintain ecosystem health for lake. However, with the decrease of the water storage, the situation of water demand balance of Qionghai Lake is grim. This article analyzed the minimum ecological water demand of Qionghai Lake according hydrology and ecological function of urban lake, based on the calculation of inputoutput balance of water. The results showed that ： the water volume balance of Qionghai Lake was-0.344 billion cubic meters and in deficit state. The minimum ecological water was 2.4909×10^8m^3 according ecological function of urban lake and the percentage of the water demand for pollutant cleaning was 20.55%. As the growing of water demand and pollution, water required for the ecological environment will be difficult to guarantee and improvement measures were proposed.
