| 摘 要： | 针对水利工程建成运行后对下游河段流量过程变化造成的鱼类原有栖息地面积减小和质量降低的潜在生态问题,对拟建息县枢纽工程闸下4.9 km河段内采用栖息地模拟法进行环境流量研究。采用MIKE数值模拟与HSI栖息地模型结合的方法,通过分析自然状态下研究河段的水流特性及鱼类栖息地现状,讨论了在不同生命期不同流量对鱼类栖息地的影响,确定了适宜环境流量范围,为水利工程建设后水生生物栖息地保护提供理论和方法指导。

| Abstract: | In view of the potential ecological problems of the reduction in the area and quality of fish habitats due to changes in the flow processes in the lower reaches of the hydraulic engineering after its completion and operation, the habitat simulation method was used to study the environmental flow in the 4. 9 km section of the proposed Xi County hub project. By using the method of combining MIKE numerical simulation with HSI habitat model, this paper discussed the effects of different flow rates on fish habitat in different life stages and determine the appropriate flow range by analysis of the water flow characteristics and the status of fish habitats in the study river section under natural conditions, providing theoretical and methodological guidance for the protection of aquatic habitats after hydraulic engineering construction. |
