摘要
为分析东北虎在成长过程中饲料量随年龄增长的变化情况,应用耗散结构理论对东北虎的生命系统进行了研究,并利用SPSS软件建立了东北虎年饲料总量与年龄的关系模型。结果表明:东北虎的生长过程可分为3个阶段:在2～6岁时,年饲料量随年龄的增长而增加;6～10岁时,年饲料量的变化情况不明显,即趋于稳定;10岁以后,年饲料量随年龄的增长而逐渐减少。年饲料量与年龄的回归方程的决定系数为R2=0.814,回归方程拟合度较高。
The theory of dissipative structure was applied to study the life system of Amur tiger in order to analyze the changes of the amount of feed with increasing age in the process of growth. And a mathematical model for the relationship between annual amount of feed and age was established by SPSS. Results showed that the growth process of Amur tiger could be divided into three stages. From two to six years old, the annual amount of feed increased with age, while from six to ten years the changes of feed amount was not obvious, that is to say, it tended to be stable. After ten years, the amount reduced gradually with increasing age. The correlation coefficient of the established regression equation is 0. 814, and the fitting degree is higher.
