Research on regeneration approaches of Korean pine forests

Abstract

After expounding the theory and feasibility of regeneration approaches of Korean pine (Pinus koraieusis) forests, the concrete measurements are put forth. There are two ways for Korean pine regeneration on clearcutting blanks: One is to keep such broad-leaved trees as birch that is naturally generated and to plant Korean pine trees with low rather than high densities so as to develop even aged broad-leaved Korean pine stands; The other is to regenerate r-strategy species with high density as transition stands at first; and then to form pure Korean pine forests through thinning. To regenerate Korean pine under canopies is an efficient approach to quicken Korean pine stands recovering, especially under such broad-leaved forests as oak stands.
