建立镇江长江豚类保护区可行性对策探讨

近年来,由于长江水环境的剧烈变化,生活在其中的长江豚类的栖息生境及群体分布状况发生了很大的变化,长江豚类的生存状况日趋恶劣,亟待探索新的保护对策。根据笔者多年的考察,长江豚类的适宜栖息生境及其生活群体均明显从中游向下游迁移;农业部组织的长江豚类同步考察也多次证实,长江下游一些特定水域内豚类数量对逐年增多。据此,笔者提出,在当前长江豚类迁地保护面临困难的严峻情况下,宜首先实施长江豚类自然栖息地的就地

DISCUSSION OF FEASIBILITY OF ESTABLISHING ZHENJIANG YANGTZE DOLPHIN NATURE RESERVE

Because of influence of irrigation works and degradation of water environment in Yangtze River,the living condition of two kinds of dolphins: Lipotes vexillifer and Neophocaena phocaenoides, is worsening and their distribution is changing.And in the lower reach of Yangtze River,because the water transport is busy and influence of people is strong,dolphins in the lower reach of Yangtze River have been killed accidentally.It is urgent to find new ways to protect them.Basing on years of research and study,some dolphins were often discovered in He Chang Zhou water area of Yangtze River in Zhenjiang,Jiangsu.Because of good environment of He Chang Zhou water area,the great importance attached by the local government,the effective management and the powerful scientific research ability,the nature reserve could be set up there.According to this,the authors put forward the tentative plan of establishing dolphins nature reserve in He Chang Zhou water area,and discussed the feasibility of establishing the nature reserve.The authors thought that the dolphins nature reserve could protect dolphins in the lower reach and buy time for other conservation measures.
