长白山林区次生阔叶林冠下红松人工更新与培育技术

Study on artificial regeneration of Pinus koraiensis under secondary broad-leaved forest canopy

通过对长白山林区林隙环境、林隙对红松生长的影响及采伐强度对阔叶树生长、红松更新的研究 ,为科学地确定冠下红松更新的最佳上层郁闭度 ,提高林分生长量 ,确定红松采伐年龄 ,促进天然林保护工程的发展提供科学的依据和技术。

Characteristics of forest gaps of Changbai mountain, the effects of forest gap on tree growth of Korea pine (Pinus koraiensis) and the effects of forest cutting intensity on growth of broad-leaved trees and the pine regeneration were analyzed in this paper. The result laid a foundation for determining the optimum canopy coverage to the pine regeneration under canopy and the cutting age of the pine forest.
