摘要/Abstract

摘要： 使用Richard,Logistic,Korf,Mitscherlich,Schumacher,Weibull等6种理论生长方程拟合了不同立地条件下油松人工林单木树高生长过程,从中选出模拟效果最优的生长方程。研究结果显示:三参数理论生长方程Logistic、Weibull、Richard、Korf对油松树高生长拟合的精度基本相近,明显高于二参数的Mitscherlich、Schumacher方程;立地指数显著影响各方程渐进线参数和形状参数,将立地指数引入各理论生长方程中,构建了模拟油松人工林单木树高生长精度最优的预测方程为Logistic式;使用未参加建模的油松解析木数据对构建的预测方程进行T检验,发现预测值与实测值之间无显著差异(P=0.6213>0.05)。可见,本文构建的预测方程可以准确预测油松人工林单木树高生长过程,为油松人工林科学经营提供重要参考。

Abstract: Richard,Logistic,Korf,Mitscherlich,Schumacher,Weibull equations were used to simulate individual tree height growth of Pinus tabulaeformis plantation with different site indexes.The result showed that simulative precision of three parameters growth equations(Logistic,Weibull,Richard,Korf)were similar,and were significantly higher than those of the two parameters equation(Mitscherlich,Schumacher equation);Effect of site indexes on the progressive line parameters and shape parameters of the equation was significant.Individual tree height growth model of Pinus tabulaeformis plantations was constructed with the site indexes.The best forecast equation was the Logistic equation. Using some data of Pinus tabulaeformis plantation plot that are not used for building models to test,the result showed that the measured values and simulated values of height had no significant difference(p=0.6213>0.05).Therefore,the equation was able to predict accurately height growth of Pinus tabulaeformis plantation,and provide an important reference for Pinus tabulaeformis plantation management.

Key words: Pinus tabulaeformis plantation, theoretical growth equation, height growth model
