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.
