肿节少穗竹产量是肿节少穗竹生态系统中经济指标和生态指标的最基本的数量特征值。本文系统阐述了林分各因子与产量之间的相互关系 ,进行线性和非线性数学模型拟合 ,用相关系数和标准差进行模型初选 ,再用共线性测定来决定自变量取舍与 Cp值和方差膨胀系数作比较分析 ,选出最优的、高精度、实用可行的数学模型组 ,以便指导生产实践
Spore less spike bamboo production is swollen less spike bamboo ecosystem economic indicators and ecological indicators of the most basic quantitative eigenvalues. In this paper, the relationship between each factor of forest stand and yield is systematically described. The linear and nonlinear mathematical models are fitted, the model is selected by correlation coefficient and standard deviation, and the collinearity determination is used to determine the choice of variables and Cp value And variance expansion coefficient for comparative analysis, select the best, high precision, practical mathematical model set to guide the production practice
