【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。更多还原

【Abstract】 The old-growth hardwood-korean pine (Pinus kocaiensis) forests inthe Lesser Xing’an Mts.hold a vital base in timber production in thewhole country.These forests have been exploited more than thirty yearsand have made significant contribution to the national economy.Up tonow,their forested area and volume have been greatly decreased.The ob-jective of the present study is to examine how to accelerate the processof stand rehabilitation on the cutovers.First of all,the early growthcharacteristics of korean pine and its regeneration on the logged areawith various typessof site are studied,then some measures to regenerateand to grow it well have been explored in the light of the tendency ofsuccessional development. Main content involves the improvement cuttings of selective cutoverstands and how to convert the birch-aspen stand naturally grown on theclear cuts to the stratified mixture with korean pine and the problems ofkorean-pine plantation from seedling to timber stage to make it growfast and become high-quality timber.In short,this paper essentially empha-sizes the fact that the artificial regeneration not only should be putinto action,but the great potential of natural korean pine reproduction sho-uld be also developed,together worked with intermediate treatment andsound silviculture system.It is expected that all courses of developmenttowards the hardwood-korean pine forest to be restored would be accele-rated n the region.更多还原
