摘    要:通过对福建卫闽林场光皮桦种群的调查研究,运用改单纯形法对光皮桦种群Logistic模型及其改进模型进行拟合。拟合结果表明:各模型对光皮桦种群的增长动态的拟合值具有一定的精确性和可信度。其优劣顺序为:宋1模型>张-模型>L-模型>宋2模型>李-模型>崔-模型。用多种模型对光皮桦种群的增长进行拟合,目的是给林业工作者一个参考,以便为种群生态的动态研究提供理论依据和方法。

关 键 词:福建卫闽林场  光皮桦  种群  改单纯形法  改进模型  Logistic模型  生态

Abstract:Through investigating on Betula luminiferapopulation in Weiming Forestry Centre of Fujian Province,and using modified simplex method to fit Betula lumimifera population's Logistic model and its renewed models.The result showed: Each model had definite accuracy and reliability. The order as the square sum of residues is:Song 1 model >Zhang-model>L-model>Song 2 model>Li-model>Cui-model.The aim of using several renewed Logistic models to fit Betula luminifera population and comparing the results was to offer a theoretic basis for population ecology dynamic research.
Keywords:Logistic model  renewed model  modified simplex method  Betula lumimifera
