| 摘 要： | 在分析物理生境模拟方法基本步骤基础上,结合物理生境模拟模型PHABSIM,选择长江中游夷陵长江大桥至虎牙滩江段四大家鱼产卵场进行模拟分析,建立鱼类产卵场物理生境适宜性标准,推求长江中游四大家鱼产卵场的流量和加权可利用面积的关系。模拟计算结果,四大家鱼产卵期适宜环境流量为7500～12500m3/s,最适宜环境流量为10000m3/s,该研究结果可为开展三峡水库生态调度措施以保护水库下游四大家鱼产卵繁殖提供参考依据。

| Abstract: | A physical habitat simulation model(PHABSIM) was used to simulate the physical habitat of four major Chinese carps in their spawning grounds in the middle Yangtze reach from Yiling Bridge to Hu Yatan.A physical habitat suitability standard of these carps was established,and the simulation was used to develop a relationship between the flow and the weighted usable area(WUA) of these grounds.The results show that the optimal environmental flow is 7500~12500m3/s and the most optimal environmental flow is 10000... |
