柴河林业局樟子松人工林资源的现状与抚育间伐的研究

Research on Status and Intermediate Cutting of Pinus sylvestris var. mongolica Plantation Resources in Chaihe Forestry Bureau

黑龙江省森工林区柴河林业局现有樟子松人工林2630hm2,幼龄林所占比重较大,达到51.56％,中龄林、近熟林和成熟林总和占48.44％.对樟子松人工林进行抚育间伐,应遵循密度效应规律,保留合理密度,促进林分生长.樟子松人工林应在12～15年开始抚育伐,采用中度的采伐强度为宜.

Chaihe Forestry Bureau exists 2630hm2 of Pinus sylvestris var. mongolica plantation, young forest accounts for the larger proportion, reaching 51. 56%, the rest of the mid age forest, near mature forest and mature forest account for 48. 44%. As a major means to adjust the stand density, intermediate cutting should follow the density effect law, maintain reasonable density to promote the stand growth. P. sylvestris var. mongolica plantation should start thinning in 12- 15 years, and the moderate cutting intensity was appropriate.
