葛洲坝下游河势调整工程对中华鲟产卵场的影响
Influence of river regime adjustment project on Chinese sturgeon spawning sites downstream of the Gezhouba Dam
摘要
Abstract
The change of hydrological conditions can bring a series of influence to aquatic breeding habi-tat, and evaluation of the influence may provide a basis for protection and reconstruction species habitats. A two-dimensional unsteady hydrodynamics model based on the bathymetry before and after the river re-gime adjustment project was set up to simulate flow characteristics in the whole spawning period. Changes of the bathymetry,flow field,vorticity and the correlation coefficient between discharge and the correspond-ing flow parameters were compared, as well as the changes of the spawning location and spawning quanti-ty, to analyze the influence of the hydraulic changes on the Chinese sturgeon spawning. The results show that the river regime adjustment project raises the elevation of up-spawning site, increases the flow turbu-lence, decreases the correlation of discharge and flow parameters, and reduces the flow turbulence of down-spawning site.关键词
