葛洲坝大江泄流对中华鲟产卵场空间分布特征的影响
Effect of Gezhouba Dajiang discharge on space distribution features of Chinese sturgeon spawning grounds
摘要
Abstract
Gezhouba dam building blocks the migration route of the Chinese sturgeon,forcing to form new spawning grounds under the gezhouba dam 4 km range,therefore,Gezhouba discharge would affect the spatial distribution of the Chinese sturgeon spawning grounds.For studying the effect of Da-jiang power plant discharge variation on the spatial distribution characteristics of Chinese sturgeon spawning habitat suitability under the condition of Gezhouba small discharge,a deep analysis and re-search was made on the basis of 3 D hydrodynamic mathematical model and spawning habitat evaluation model of Chinese sturgeon spawning grounds.Results show that the increasing of Dajiang power plant unit discharge by within 200 m3/s can increase the Chinese sturgeon spawning habitat suitable values, which is beneficial to promote Chinese sturgeon naturally reproduce.The increase of each unit dis-charge in Dajiang power has a certain impact on spatial distribution of the Chinese sturgeon spawning grounds.When each unit flow increases less than 200 m3/s,the area of Chinese sturgeon spawning grounds would enlarge,and spawning location would expand from the right bank to the left bank,while Chinese sturgeon would get broader spawning space.The conclusion can provide reference for the eco-logical benefits of Gezhouba units under increasing capacity operation.关键词
