摘　　要：2005年在黑龙江碧水中华秋沙鸭自然保护区,对救助饲养的中华秋沙鸭从出壳到30周龄的体质量、体长、翅长、尾长、喙长进行了测量与分析。结果表明:中华秋沙鸭早期的生长速度快,随着年龄的增加,生长速度下降,其中第4周相对生长值最大(118.5%),绝对生长82g,第8周绝对生长值最大(354.4g),生长率为62.6%,到13周体质量稳定,生长基本停止达到成熟,体质量与体长、喙长、尾长、翅长相关系数分别为0.967、0.966、0.949、0.943。基于Logistic模型进行非线性回归分析,运用迭代分析建立了中华秋沙鸭体质量的非线性回归方程。通过体质量与4个主要体尺间的回归分析得到了中华秋沙鸭体质量与体尺指标的最优回归方程。A research was conducted on the changes of body weight, body length, wing length, tail length, and beak length ot Merganser （Mergus squamatus） fed after rescued from birth to 30 weeks in Heilongjiang Bishui Nature Reserve for Mergansers in 2005. Results showed that the Mergansers grew quickly during the initial stage, and then grew slowly with increase age. The Mergansers showed a highest relative growth value of 118.5% and an absolute growth value of 82 g during the fourth week and a highest absolute growth value of 354.4 g and a relative growth value of 62.6% during the eighth week. The body weight was stable during the thirteenth week. The correlative coefficients between body length, beak length, tail length, wing length and body weight were 0. 967, 0. 966, O, 949, 0. 943 respectively. A nonlinear regression equation was built by iterative analysis and nonlinear regression. An optimal regression equation for the body weight and the four body indexes was obtained.
