摘　　要：文章探讨了维持生态系统平衡所需的水量,包括河湖水生生物生存的最小需水量;防止河流系统泥沙淤积 的河道最小径流量;水体自净的最小基流量;防止海水入侵的河道最小流量;防止河湖断流、湖库萎缩的河道最小径 流量。必须合理预留生态环境需水,以实现水资源的科学配置和有效管理,维持生态平衡。The paper discusses the water demand volume for ecologic system equilibrium including the minimum water demand volume for water living things in lake and river; the minimum runoff against river bed sedimentation; the minimum base flow for water self - purification; the minimum flow for against sea water intrusion; the minimum run off preventing water interception of river and lake dried up. The environmental water demand is considered for scientific disposition and management and ecologic equilibrium.
