摘要: 小兴安岭阔叶红松林是全国木材生产的重要基地,森林开发利用已有30多年历史。目前森林面积和蓄积量锐减,如何加速森林恢复的进程,是本课题研究的目的。本文根据多年试验和调查资料,分析了红松早期生长特点和各类型采伐迹地更新的过程,并根据森林演替发展趋向,探讨阔叶红松林恢复的措施。全文强调既积极进行人工更新,又要充分利用红松天然更新的潜在力量,并与森林抚育和合理采伐相结合,以期全面加快阔叶红松林的恢复。

Abstract: The old-growth hardwood-korean pine (Pinus kocaiensis) forests in the Lesser Xing'an Mts.hold a vital base in timber production in the whole country.These forests have been exploited more than thirty years and have made significant contribution to the national economy.Up to now,their forested area and volume have been greatly decreased.The objective of the present study is to examine how to accelerate the process of stand rehabilitation on the cutovers.First of all,the early growth characteristics of korean pine and its regeneration on the logged area with various typessof site are studied,then some measures to regenerate and to grow it well have been explored in the light of the tendency of successional development. Main content involves the improvement cuttings of selective cutover stands and how to convert the birch-aspen stand naturally grown on the clear cuts to the stratified mixture with korean pine and the problems of korean-pine plantation from seedling to timber stage to make it grow fast and become high-quality timber.In short,this paper essentially emphasizes the fact that the artificial regeneration not only should be put into action,but the great potential of natural korean pine reproduction should be also developed,together worked with intermediate treatment and sound silviculture system.It is expected that all courses of development towards the hardwood-korean pine forest to be restored would be accelerated n the region.
