| 摘 要： | 通过耦合分析2004年和2007年沙洋水文资料与汉江沙洋断面鱼类早期资源量监测数据,汉江中下游"四大家鱼"自然繁殖的生态水文需求为沙洋断面洪峰初始水位达到33.82～36.71 m,洪峰最高水位36.86～39.80m,上涨时间持续3～8 d,水位日上涨率达到0.44～1.50 m/d,水位上涨幅度1.55～3.14 m.结合黄家港与沙洋断面水文数据,分析发现"四大家鱼"自然繁殖对不同洪水来源有不同的响应,其产卵丰要依赖区间洪水,丹江口水库现状调度形成的洪水过程对其作用有限此外,"四大家鱼"自然繁殖与洪水过程中水体透明度存在相关性.汉江中下游"四大家鱼"自然繁殖的透明度范围在5.1～14.5cm,透明度与洪水来源直接相关,透明度指标可以作为"四大家鱼"自然繁殖的重要指标之一.
