摘要
运用典型相关分析等多元统计方法对福建省火炬松 (PinustaedaLinn .)人工林的生长与环境因子间的相互关系进行了分析。结果表明 ,对地处亚热带的福建省而言 ,火炬松的生长性状除了与年龄、密度有关外 ,与年均温、≥10℃积温呈正相关 ,与年降水量呈负相关 ,从而为火炬松的栽培区划和生产力评价提供科学依据。
This paper deals with the typical correlation between to growth of \%Pinus taeda \%Linn. plantations in Fujian Province and its environment factors by using multi\|factor statistic methods. It showed that annual average air temperature, ≥10℃ accumulative temperature and annual rainfall besides age and density related to the growth state of \%P. taeda \%in Fujian Province. The result provided a scientific basis for cultivation division and growth evaluation,
