摘　　要：生态补水对于恢复受污染水体的自然属性以及重建河道的景观功能具有重要作用。为配合滇池水体整治,本文以典型入滇河流昆明老运粮河为研究对象,基于其蓄洪、生态调节与保育及景观水体的功能界定并计算其生态需水量,同时考虑补水成本经济性进行基于满意度的需水量修正。修正后,支流小路沟、七亩沟生态需水量分别为3 100和19 000 m3/d,下游入湖段生态需水量为34 000 m3/d,其生态-经济满意度依次为80%、80%、100%。本研究对城市人工河道生态需水量的计算及基于实际的成本-效益权衡问题进行了有意义的实践,为城市人工河道补水工程的方案设计提供了一定参考价值。Ecological water compensation plays very important role for the restoration of natural properties of polluted water body and the reconstruction of landscape function of a river. In order to cooperate the restoration of Dianchi Lake,the paper took old Yunliang river of a typical river into the lake as research object,defined and calculated the ecological water requirement based on its function of flood storage,ecological regulation and landscape provision. It simultaneously considered the economy of water cost to revise the ecological water requirement based on satisfaction degree. After revision,the amount of ecological water requirements of tributaries Xiaolu Ditch,Qimu Ditch and the river＇s downstream section are 3100m^3/ d,19000 m^3/ d and 34000 m^3/ d respectively with the satisfaction degrees of ecological economy of80%,80% and 100% accordingly. The paper conducted a significant practice for the calculation of ecological water requirement and the balance of real cost and benefit,and can provide certain reference for the program design of ecological water compensation of urban artificial rivers.
