摘　　要：鱼类栖息地是河流生态系统的重要组成部分,但河流中的拦河坝却阻断了鱼类上溯洄游的通道,在一定程度上破坏了鱼类栖息地。对于有洄游习性的鱼类而言,洄游路线被阻隔可能造成种群资源下降,所以鱼类栖息地连通性修复越来越重要。针对拉萨市帕古水库工程划定鱼类栖息地保护范围,确定过鱼对象、过鱼时间并分析过鱼对象的生态习性;根据拦河坝工程现状和相关水利学计算,确定鱼类栖息地连通性修复采用补建过鱼堰的型式,并通过数值模型验证,最终确定过鱼堰设计方案。该方案设计可为类似鱼类栖息地连通性修复工程提供参考。Fish habitat is an important part of the river ecosystem.However,the barrages in the rivers have blocked the channels for fish to migrate upstream,destroying fish habitats to a certain extent.For fish with migratory habits,the blocking of migratory routes may result in the decline of population resources,so the restoration of fish habitat connectivity is becoming more and more important.This paper delimits the habitat protection range for the project of Lhasa Pagu Reservoir,determines the fish object,the time of passing the fish,and analyzes the ecological habits of the fish object.According to the current situation of dam containment engineering and related hydraulic calculation,the type and structure of the re-built fish weir for connectivity restoration are determined.In order to have more fish successfully go up the fish weir,the design scheme of the fish weir was finally determined through numerical model verification.This paper provides reference for similar fish habitat connectivity restoration project design.
