摘要:

本文以广东省龙眼洞林场在1989年种植的红锥人工林为研究对象,对不同海拔高度和造林密度下红锥近20年生长量进行分析和统计,以期得出红锥人工林适宜的海拔高度和最佳造林密度。结果表明：不同海拔高度对红锥人工林生长量影响较小,在0-300 m的海拔高度内,红锥人工林的胸径、树高和蓄积量等差异不显著；不同密度对其生长有显著影响,综合分析得出该地区红锥的最佳造林密度为800株/ hm2。

Abstract:

In this paper, the study of growth index Castanopsis hystrix planted in 1989 to nearly 20 years in different altitude and afforestation in the Guangdong Province longyandong forest, in order to get the altitude and afforestation range for optimum growth of Castanopsis hystrix plantation. The specific results are below: Overall, the effects of the DBH, tree height volume and its growth of Castanopsis hystrix Plantation By different altidude are less obvious. The Castanopsis hystrix plantation afforestation density of 800 / hm2.

Key words: Castanopsis;hystrix altidude;afforestation DBH;height
