| 摘 要： | 中华白海豚(Sousa chinensis)隶属于白海豚属，为国家一级重点保护动物。为详细了解中华白海豚骨骼的特征，对2009年2月广东阳江闸坡海边搁浅死亡的1头中华白海豚，经多步骤处理制成骨骼标本，对其骨骼数据进行全面测量和相关统计分析。结果显示，其胸椎质量与椎体高度、椎体长度之间存在显著的二次函数关系(R2=0.919 2；R2=0.840 5)；尾椎的椎体质量与椎体高度、椎体长度、椎体宽度之间均存在显著的幂函数关系(R2=0.955 0；R2=0.928 6；R2=0.866 4)；幂函数能很好地拟合V型骨质量与最大高、最大厚、最大宽之间的数学关系(R2=0.950 3；R2=0.917 4；R2=0.89)。

| Abstract: | Sousa chinensis belongs to the genus Sousa, which is one of the most important protected animals at national level. To study the characteristics of the skeleton of S.chinensis, an S.chinensis that died on the seashore in Yangjiang in February 2009 was treated with several steps to make a bone specimen, and the bone data were measured and studied by correlated statistical analysis. The results show that the mass of the thoracic vertebra has obvious quadratic function relationship with the height and the length (R2=0.919 2; R2=0.840 5). Power function relationship exists between the quality of caudal vertebra and the height, length and width (R2=0.955; R2=0.928 6; R2=0.866 4). The power function can fit the mathematical relation between the mass of V type bone and the maximum height, maximum thickness and maximum width (R2=0.950 3; R2=0.917 4; R2=0.89). |
