| 摘 要： | 1994～1999年在厦门海域进行84航次中华白海豚船只跟踪和照像,记录392只次。设20个监视站,进行239个月的逐日观察,记录12624只次。整个厦门海域700km2均有中华白海豚分布,它可溯河至近淡水的河道,但不游出外海。厦门西港和同安湾口内的近岸最多,跃出海面的次数有明显的季节差异,4～5月最多。厦门海域中华白海豚数量估计不足100只,仅40只左右有确切记录。种群数量目前仍有减少趋势,因而应就地和迁地保护并举,加强对这种国家一级保护物种的保护。

| Abstract: | During 1994-1999, 84 vessel surveys were conducted with having a photos taken, and 392 individuals were recorded. At the same time, totally 20 observation sites were established, and the record for 239 months amounted to 12 624 individuals. Chinese white dolphins occur all around Xiamen waters of 700 km2, and they may swim upstream to the Jiulong River but never swim out of Jinmen Island and Wuyu Isle. Generaly, the dolphins are sighted very close to the shore and most frequently occur in areas included west harbour of Xiamen and the mouth of Tong' an Bay. The frequency when the dolphins jumped out of the water varies with season, which is the highest in April to May. According to surveys and supplementary surveys, nearly 60 individuals are estimated in Xiamen waters, and only 40 individuals are distinctively recorded through having a photos taken. Now the population has the tendency to decrease, so in -situ and off -- situ measures should be both employed to emphasize the conservation of Chinese white dolphins, the first -- class protected species in China. |
