中文摘要: |
水电开发对于洄游性鱼类产生的负面影响最为直接,阻碍了其繁殖、索饵以及越冬等生命行为。在调查的25个水电项目中,有17个采取了鱼类保护措施,其中采取增殖放流措施的占82.4%,仅有1个项目修建了鱼道。介绍了“莱茵河-2000计划”和哥伦比亚河鱼道建设及运行效果。鱼道不单纯是洄游性鱼类的通道,更是实现大坝上下游物质与能量循环的生态廊道。国内开展鱼道适应性管理的关键问题是:建立鱼道长效运行与保障机制,对鱼道过鱼进行长效监测以及研究鱼道过鱼效果评价方法。 |

Hydroelectric development has the most negative influence on migration fish, which will directly block their propagation, foraging, over-wintering and other vital behaviors. Among the 25 hydroelectric projects which we have investigated, there’re 17 hydroelectric projects have taken measures to protect fish, which consists of 87.4 percentage of artificial releasing and enhancement and only one fishway. In this paper, we also introduced “River Rhine-2000 Plan” and the fishway construction on Columbia River. The fishway is not only the passageway for migration fish, but also provide the ecological corridor for material and energy cycling between the dam’s upstream and downstream. In order to develop domestic fishway adaptive management, the key question is that we should establish sustainable and effective operation and safeguard mechanism for fishway project, and at the same time set up the evaluation system and long-term monitoring system for fishpassage facilities’ function. |
