【摘要】 通过发现频次、卡方检验和栖息地选择指数等方法对厦门中华白海豚的栖息地选择进行了研究。结果表明，厦门中华白海豚对水深有明显的选择性，喜爱在小于20米深的水域里活动，而对潮汐变化、风向、风力和表层水温均没有表现出明显的选择性。 对在厦门水域发现的各年龄段的海豚头数进行分析，初步评价社会组织结构的合理性，通过联系度指数(AI)，计算个体间和行为间的联系度。结果表明中华白海豚个体间的联系不紧密(AI=0.0357)，社会组织结构具有较高的流动性。在野外主要观察到了摄食、旅行、游戏、生殖、抚幼等行为。通过AI指数的分析，摄食与旅行、摄食与游戏、游戏与抚幼、游戏与旅行联系较密切。摄食行为、旅行行为和游戏行为主要集中在厦门西港和鸡屿至青屿、浯屿一带水域内，尤以鸡屿至青屿、浯屿一带水域内的行为丰富度最大，说明该区域对厦门中华白海豚的保护至关重要。更多还原

【Abstract】 Habitat selection of Chinese white dolphins (Sousa chinensis) inhabiting the Xiamen Bay was analyzed by using finding frequency, x~2-test, and habitat selection index. High level of selection of water depth under 20 meters was found, whereas no significant selection was found to other environmental conditions such as tide change, wind direction, wind power, and temperature of surface water etc.Analyses on the number of Chinese white dolphins (Sousa chinensis) at different ages in order to evaluate social organization. The association of individuals and behaviors was measured by association index (AI). The results indicate that the association between individuals was not tight (AI=0.0357) and the social organization was highly influid. The dolphin’s behaviors in the Xiamen waters inclue feeding, traveling, playing, procreating, care-giving et al. It was found that the association between feeding and traveling, feeding and playing, playing and care-giving, playing and traveling was tight. The dolphin’s behaviors inclde feeding, traveling and playing were mostly observed in Xigang, Jiyu, Qingyu, Wuyu water areas. The abundance ratio of behavior observed in Jiyu, Qingyu, Wuyu water areas were highest, it indicates that these areas are important to the ptotection of Chinese white dolphins (Sousa chinensis) inhabiting the Xiamen Bay.更多还原
