英文摘要	In recent years, human activities appear to present the greatest threat to the Chinese white dolphin (Sousa chinensis). Increasing death records of this species in Xiamen have already become a focus of attention among the local government, the public, and the media. A comprehensive understanding about the status of Xiamen population is important not only to evaluate the conservation measures taken previously, but to design adaptive measures appropriate to this population. In this study, a survey using line-transect methodology was carried out to cover an area of about 700 km 2 in Xiamen waters. A total of 102 separate sightings were made on 6157 km of transect line. The abundance estimate ranged from 67 (CV = 41.6%) to 93 (CV = 26.34%), with an average of 86 (CV = 20.16%). Overall, Xigang (West harbor) and Jiyu represented the major area of distribution in Xiamen. Significant seasonal changes in distribution were found. In spring, significant numbers of dolphins occurred in Xigang and few in other areas, while in other seasons, the sighting rate in Xigang decreased relatively with sightings in Jiyu, Dapan, and Dadeng increasing obviously, suggesting an outward movement pattern of Chinese white dolphins from the inside harbor to outside waters after spring. Some suggestions for redesigning the Xiamen Nature Reserve and other management measures are put forward. (c) 2007 Published by Elsevier GmbH on behalf of Deutsche Gesellschaft fur Saugetierkunde.
