摘　　要：在水资源长期短缺的北方地区,拦河蓄水形成的串联型河流坝式景观水体几乎在每个城市都可以看到。为计算维持这种以水景观为主的人工河流生态系统基本健康的最小需水量,以滹沱河水环境修复段为例,构造描述"串联型坝式景观水体"水质、水量变化的综合数学模型,提出了水质、水量相结合的河流坝式景观水体生态需水补水方案。结果显示:75%频率降水情况下,滹沱河水环境修复段现状水平年最小需水量为3 450万m3,并给出了明确的补水时机和补水量,为北方串联型河流坝式景观水体的生态保护提供了支撑。Innor thern China,where water resources are in longterm shortage,it is common in nearly every city to see serial river-dam-type landscape water bodies built to obstruct rivers and retain water.To calculate the minimum water required tosustain the ba sichealth of such an artificial river ecological system consisting mostly of water landscape,this paper studiedthe case of a segment of Hutuo River needing rem ediation of wat er enviro nment,built an integrated mathem atical model thatdescribes the water quality and quantity chang es of the"serial dam-type landscape water body",and proposed a scheme tomeet the ecological water demand of river-dam-type landscape water bodies with consideration to both water quality andquantity.The results showed that under the circumstance of75%fr equency of rainfall,the minimum water required by thissegment of Hutuo River needing remediation of water environment is34500t ho usand m3/a.This paper also providedt heexplicit dates and amount of water supply,and prov ided support for the ecological protection of northern serial river-dam-type landscape water bodies.
