湖北天鹅洲故道江豚的活动与行为

本文对湖北天鹅洲故道中捕自长江的６头江豚（ＮｅｏｐｈｏｃａｅｎａｐｈｏｃａｅｎｏｉｄｅｓＣｕｖｉｅｒ）之活动及行为进行了较为详细地研究，描述和分析了江豚的群体家域、活动能力、活动在各研究区的季节性变化及其与豚活动相关的一些环境因素和豚的一些行为。不但为保护和管理这种国家二类保护动物提供理论依据；更重要的是，为在此故道建设的白豚（ＬｉｐｏｔｅｓｖｅｘｉｌｌｉｆｅｒＭｉｌｌｅｒ）自然保护区作了进一步的生态评价，并提出了合理的建议。

MOVEMENT AND BEHAVIOR OF FINLESS PORPOISE (NEOPHOCAENA PHOCAENOIDESCUVIER)ATSWAN OXBOW, HUBEI PROVINCE

The paper deals in detail with the movement and behavior of 6 finless porpoises living in the Swan Oxbow, Hubei province. All these animals were introduced from the Yangtze River or born in the Oxbow in Mar.-May, 1990. The movement characters of the porpoises such as herd home range, movement capabilities, the seasonal change of the movement in the research areas and the environmental factors which influence the movement, as well as their behaviors were described and analysed. The results showed that the Oxbow was suitable very well for the porpoises. We gave a further ecological assessment and rational suggestions for the Baiji Nature Reserve which will be established in this Oxbow. We can also obtain the information for conservation and management of the secondary order protected aquatic mammal by our work.
