摘要
通过严密的数学证明，发现了前人关于作物生长温度效应非线性模型之间的内在联系，修正了有关学者对模型参数定义的局限性，提出了一个通用的作物生长温度效应非线性模型，本研究还将该模型与笔者最近提出的基于高斯方程的非线性模型进行了比较研究，介绍了应用SAS软件求取两个模型相关参数的方法。并以马铃薯生育期模拟为例进行了实证研究，表明这两个模型均有良好的适用性。
By a serious strict demonstration, the mathematical relationship among several temperature driven nonlinear models (TDNLM) is found in this study. The study also amends the limitation of these TDNLM in biological usage. After that a general TDNLM is advanced in this study. A comparative study of the new model to Gauss function based TDNLM submitted by our research group recently is carried in this paper. The methodology to obtain the parameters of these two models by SAS safe ware is introduced. With the example of potato phonology development, an active study is given in this paper. The results show that the two models are of wide usage.
