研究了池堰式鱼道中不同堰型的水力特性及其对鱼类向上游洄游的影响，提出了有利于鱼类向上游洄游的堰型优化设计。进行实验以估计不同堰类型的水力条件，以确定测试堰的整体性能。结果表明，矩形直堰比锯齿堰和梯形直堰更有利于水流的稳定，并为鱼类提供了一个栖息地，有利于鱼类向上游洄游。(C)2001 Elsevier Science B.V.保留所有权利。
This study deals with hydraulic characteristics for different weir types and effects on upstream migration of fish in a pool-weir fishway, and presents an optimal design of weir for an easy upstream migration. Experiments were performed to estimate hydraulic conditions for different weir types to determine the overall performance of the weir tested. The results showed that a rectangular weir with a notch installed in a straight configuration was preferable to one in a zigzag configuration or to a trapezoidal weir, since it made the flow stable and created a resting place for fish in the pool and thus made it possible for the upstream migration of fish.
