Study on the cutover land of the hardwood-Korean pine forest for reproduction in the Xiaoxingan Mountains of northeast China

Abstract

The old-growth hardwood-Korean pine(Pinus koraiensis) forests in the Xiaoxingan Mts. hold a vital base in timber production in the whole country. These forests have been exploited more than 40 years and 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 or. the cutovers. The early growth characteristics of Korean pine and its regeneration on the logged area with various types of site were studied. The measures to regenerate and to grow it well have been explored in the light of the tendency of succession. 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 proper 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 in the region.
