四大家鱼产卵水文水动力特性研究综述

A Summary of Hydrology and Hydrodynamics Conditions of Four Chinese Carps' Spawning

四大家鱼是中国重要的经济鱼类,长江是四大家鱼的天然种质库,长江四大家鱼的自然繁殖数量对四大家鱼的资源保护意义重大。四大家鱼产卵与河流水文水动力关系密切。较为全面的阐述了四大家鱼产卵与水温、涨水过程的关系,并对四大家鱼产卵场的分布和水动力特性进行了简要描述。本工作将为针对四大家鱼产卵的水库生态调度和四大家鱼产卵场修复提供一定技术支持。

Four Chinese Carps（FCC） are very important economy fishes in China, and the Yangtze River is their nature germplasm library. The scale of FCC＇s natural reproduction is of great significance to the protection of their resources. The spawning of FCC has closely relations with the hydrology and hydrodynamics conditions in rivers. In this paper, a comprehensive represent of the relations between the FCC＇s spawning and the water temperature and swelling is given, and a brief description of the distribution of FCC＇s spawning grounds and their hydrodynamics characters is also given. This work can provide some technical support for reservoir operation to the FC＇s spawning and also for the restoration of FCC＇s spawning grounds, which is very important to the protections of FCC＇s germ- plasm resources and aquatic ecosystems.
