摘　　要：华北落叶松为华北地区的重要用材树种,生长模型的构建对于其生长过程和生产力的研究及科学经营有重要意义。笔者在山西芦芽山自然保护区内设置华北落叶松样地,对样地内的标准木进行树干解析,通过回归分析研究其树高生长模型、胸径生长模型和树高曲线的最优模型。结果表明,华北落叶松树高的最优生长模型为逻辑斯蒂模型,模型的决定系数和残差平方和分别为0.9969和1.7441;胸径的最优生长模型为韦布尔模型,模型的决定系数和残差平方和分别为0.9988和1.0172;树高曲线的最优模型为坎派兹模型,模型的决定系数和残差平方和分别为0.9970和0.9953。Larix principis-rupprechtii is an important timber tree species in North China,the construction of growth model have great significance to the management and study on its growth process and productivity.Sample plot of Larix principis-rupprechtii was set up in Nature Reserve of Luya Mountain and the trunk of standard trees in the sample plot were analyzed.The optimal growth models of tree height,DBH and tree height curve were studied through regression analysis.The results showed that the optimal model of tree height was Logistic equation,the value of R2 was 0.9969 and that of RSS was 1.7441.The optimal model of DBH was Weibull equation,the value of R2 and RSS were 0.9988 and 1.0172 respectively.The optimal model of tree height curve was Gompertz equation,the value of R2 and RSS were 0.9970 and 0.9953 respectively.
