| 摘 要： | 应用99块湿地松人工林标准地调查资料,以林分年龄、立地指数为自变量,利用Richards模型拟合各林分因子(直径、树高、蓄积等)生产过程;采用非线性麦夸特迭代求解法,确定各林分因子Richards模型参数,并进行模型检验和误差分析,在此基础上依据各林分因子生长模型编制16指数级湿地松人工林经验收获表.

| Abstract: | The data of 99 standard plots for Pinus elliottii plantations were adopted to describe the growth process of the stand factors(diameter,tree height,volume,etc.)with Richards equation,taken stand age and site index as independent variable.The parameters of Richards equation were determined by using nonlinear Marquardt computation,at the same time,the model and its error were tested and analysed respectively.Based on growth equations of the stand,the 16 index level empirical yield table of Pinus elliottii plantation was compiled. |
