摘要
本文在总结不同尺度河流栖息地水力学表征参数的基础上,以南水北调西线工程水源区雅砻江甘孜河段生态保护为例,从中观尺度栖息地保护角度,依据长系列流量资料和水文站断面资料,探讨了少资料区生态水力学指标的获得方法,以及水利工程建设对该河段鱼类产卵的影响,本方法为资料缺乏地区水生态环境保护提供了思路,为水利工程生态调度研究提供参考。
On the basis of summarizing the hydraulic parameters of river habitat at different scales, the method to obtain the ecohydraulic indexes of the data-deficiency region is studied herein from the aspect of the protection on the habitat at the mediumscale in accordance with both the long-term flow data series and the data of the hydrologic sections from the local hydrological stations by taking the eco-protection of the Ganzi Reach of Yalongjiang River within the water source area for the West-route of the South-to North Water Transfer Project as a study case, and then the impact from the construction of water resources project on the fish spawning therein is also discussed. This study method can not only provide a concept for the protection of the water eco-environment in the data-deficiency region, but also can give a reference for the study on the eco-operation of water resources project concerned.
