摘要: 对福建西北地区栽培的湿加松Pinus elliottii × P. caribaea 12年生林分树高与胸径生长分布进行统计分析。结果表明,林分树高分布在3~14 m范围内,胸径生长分布于2~22 cm,林分的经济生长性状呈正态分布。在同等立地条件下,湿加松早期树高生长优于乡土树种马尾松,但马尾松胸径生长6年后有更好的生长量,12年生后胸径生长相接近,马尾松12年生林分中平均木单株材积优于湿加松林分,不过11年生后开始减缓,而湿加松保持持续生长势头。由材积生长来看,各树种个体材积生长正处于快速生长期,湿加松材积生长表现出较强的生长趋势。

Abstract: The growth distribution of height and breast-diameter of 12-year stands of Pinus elliottii ? P. caribaea were studied with statistics analysis in the northwest of Fujian. The results indicated that the growth distribution of height and breast-diameter showed the normal-distribution and the distribution of height and breast-diameter were respectively from 3 m to 14 m and from 2 cm to 22 cm. The early-height-growth and of P. elliottii ? P. caribaea was better than that of P. massoniana, but the diameter breast height growth of P. massoniana was better after 6 years, until growing 12 years the breast-diameter growth of P. massoniana and P. elliottii ? P. caribaea were approximate. The volume-growth of average individual of P. massoniana comparing with P. elliottii ? P. caribaea were better in 12 years stands, but the volume-growth of average individual of P. massoniana became lower from 11 years and the volume-growth of average individual of P. elliottii ? P. caribaea kept strong growth. The volume-growth of the different individual was in the fast growth period and the volume-growth of P. elliottii ? P. caribaea was strong growth.
