摘要
为探究红锥人工林适宜的造林密度和海拔,以广东省龙眼洞林场1989年种植的红锥(Castanopsis hystrix)人工林为研究对象,以森林资源二类调查数据为基础,测定不同海拔和造林密度下5,10,15,20 a生红锥的胸径、树高和蓄积量。结果表明:海拔对红锥人工林生长量影响较小;造林密度对红锥人工林生长量有显著(P<0.05)或极显著影响(P<0.01),综合分析得出红锥在该地区的最佳造林密度为800株/hm2。
This paper was aimed to acquire the best afforestation akitude and density for optimum growth of Castanopsis hystrix plantation. C. hystrix plantation was a main research object which was planted in Guangdong Longyandong Forest Farm in 1989. Its growth of DBH, height and volume in different altitude and density for nearly 20 years was measured based on forest resource inventory data for management. The results showed that altitude had limited effect on the growth of C. hystrix plantation, while the impacts of afforestation density presented the significant （P〈0.05 or P〈0.01 ） effects on increment of C. hystrix plantation. C. hystrix planted in the density of 800 trees/hm2 was verified to have the best growth performance.
