拦河大坝的建设影响了河流的连通，阻隔了水生生物尤其是鱼类的洄游通道。为维持大坝上下游鱼类遗传交流和生物的多样性，通过对已运行船闸内鱼类资源的调查分析，提出在传统船闸中增设辅助设施，利用船闸过鱼的新思路，使传统船闸的功能得以扩展。在通航河流上，采用过鱼式船闸，能增加鱼类的通过率，减缓工程建设对洄游鱼类的阻隔影响，更好地保护河流生态环境。

The construction of dam affects the river connection, blocks the breeding migration of aquatic organism, especially for fishes. To maintain the heredity and biodiversity of the fishes in upstream and downstream of dam, through the investigation on the fish resources in the ship lock, a new thought of constructing auxiliary facilities in ship lock to increase ship lock function for fish passing is proposed. The passing-fish type ship lock in navigation channels will increase fish passing rate over dam, al-leviate the negative impact of dam construction on fish migratory to better protect the ecological environment of rivers.
