一类非自治的Logistic生长曲线及其应用

A kind of nonautonomous Logistic growth curve and its application

通过对决定单种群或有机体相对生长速率的机理进行研究 ,引入了一类非自治的 L ogistic生长方程 ,对其解的性质进行了系统研究。结果表明 ,该模型不仅可以拟合受密度与时间两个因素限制的生长过程 。

The paper introduced a new kind of nonautonomous Logistic growth equation by studying the decided principle of single population or organism body relative growth rate,the systematic research to the solutions character was also done.The result showed:The new model not only can fit the growth process that is restricted by the density factor and time factor,but also have the flexibility.
