| 中文摘要: |
| 卵场位置是长江流域四大家鱼资源调查的重点。对于四大家鱼产卵场位置的定位以及影响家鱼产卵繁殖的水文、水流条件等非生物的因素，一般以河段邻近水文站观测数据来推算或近似。本文采用MIKE 11 商业软件，基于三峡库区622个河道断面，模拟了2002～2003年三峡库区水动力变化，而后以重庆市云阳断面为起点，根据该断面2002～2003年四大家鱼捞获卵、苗的发育时间，推求出长江上游重庆至云阳4个产卵场的位置，最后对模型法推求产卵场位置的不确定性进行了分析。 |
| 英文摘要: |
| The hydrodynamic variation process of the river flow in the reservoir of Three Gorges Project was simulated by using the software Mike 11 based on the hydrological observation data from 2002 to 2003. According to the growth status of spawns or fries captured at the Yunyang Gauge Station, Chongqing City, the spawning sites of different kinds of Chinese carps can be determined by the flow distance based on the hydrodynamic calculation results. The accuracy of the spawning sites determined by this method is much better than those calculated according to the averaged velocity of the river. The uncertainty of this method is also discussed. |
