为确定太行山南麓栓皮栎人工林合理的造林密度,以河南省国有济源市大沟河林场30年生的6种不同密度的栓皮栎人工林作为研究对象,采用样地调查方法,对不同密度的栓皮栎人工林的林木生长指标进行调查。结果表明,栓皮栎的林分密度与平均树高、平均胸径、平均冠幅和单株平均材积关系密切。平均树高、平均胸径、平均冠幅和单株平均材积均随着林分密度的逐渐增大而减小。太行山南麓30年生的栓皮栎人工林的最佳林分密度应控制在1400株/hm<sup>2</sup>,有利于栓皮栎林木的生长。
為確定太行山南麓栓皮櫟人工林閤理的造林密度,以河南省國有濟源市大溝河林場30年生的6種不同密度的栓皮櫟人工林作為研究對象,採用樣地調查方法,對不同密度的栓皮櫟人工林的林木生長指標進行調查。結果錶明,栓皮櫟的林分密度與平均樹高、平均胸徑、平均冠幅和單株平均材積關繫密切。平均樹高、平均胸徑、平均冠幅和單株平均材積均隨著林分密度的逐漸增大而減小。太行山南麓30年生的栓皮櫟人工林的最佳林分密度應控製在1400株/hm<sup>2</sup>,有利于栓皮櫟林木的生長。

In this paper, 6 densities of 30-year-old Quercus variabilis plantations on Dagouhe State-owned Forest Farm in Jiyuan City, Henan Province were used as the study objects in order to determine the rational forestation density of the plantations at the southern foot of Taihang Mountains. A sample -plot survey was made on the growth indexes of the plantations with different densities. The results showed that there was a close correlation between the stand density and the mean tree height, mean DBH, mean canopy diameter and the single mean volume. The mean tree height, mean DBH, mean canopy diameter and the single mean volume decreased with the progressive increase of the stand density. The optimum stand density of the 30-year-old Quercus variabilis plantations at the southern foot of Taihang Mountains should be controlled at 1400/hm2, which would be conducive to their growth.
