福建省火炬松人工林生长特性的研究

STUDY ON GROWTH CHARACTERISTICS OF PINUS TAEDA PLANTATION GROWN IN FUJIAN PROVINCE

对福建省火炬松人工林生长特性以及不同栽培区火炬松的生长规律进行了对比分析。结果表明 :Richards函数是福建省火炬松优势木生长的最佳模型 ;对树高曲线方程而言 ,h=a0 da1 最符合火炬松树高随直径变化的规律。随着栽培区适宜程度的降低 ,火炬松胸径生长量随之降低 ,胸径平均生长量、材积连年生长量达到最大值的年龄也随之提早。

Based on the contrast and analysis of the growth characteristics and patterns of Pinus taeda plantation in different planting zones in Fujian Province,the results showed that,Richards function was the best model for growth of the dominant trees of Pinus taeda in Fujian Province.The height curve equation h=a 0d a1 was most accordant the pattern of height with DBH.With the decrease of suitable degree of planting zones,the DBH increment decreased,and the year when the mean DBH increment and current annual ...
