Abstract

This study was carried out to the structure of plant community, and ecological succession sere of forest ecosystem in Soguemgang Valley, Odaesan National Park. Fifteenth plots(size is $20m{\times}20m$) were set up and the results analyzed by DCA which is one of the ordination technique showed that the plant communities were divided into seven groups which area community I(Quercus variabilis-Pinus densiflora community), II(Pinus densiflora community), III(Pinus densiflora-Quercus variabilis community), IV(Pinus densiflora-Quercus serrata community), V(Quercus serrata community), VI(Pinus densiflora-Deciduous broad-leaved plant community), VII(Cornus controversa-Carpinus laxiflora community). Shannon diversity index per $400m^2$ was to 0.7777 to 1.1440 and the age of Pinus densiflora 86 years old, Quercus variabilis was ranged from 66 to 87 years old, Quercus serrata was ranged from 51 to 62 years old, Carpinus laxiflora was 94 years old. In 2013, the succession trend was predicted Pinus densiflora${\rightarrow}$Quercus variabilis, Quercus serrata ${\rightarrow}$Cornus controversa, Carpinus laxiflora. The ecological sucession progress has declined power of the Pinus densiflora and the increased power of the deciduous broad-leaved and Quercus spp. in Soguemgang Valley, Odaesan National Park. Quercus serrata and Quercus variabilis communities that judged Pinus densiflora were progressing by direction of landform. The southern slopes vegetation were progressing for Quercus variabilis, the northern slopes vegetation were progressing for Quercus serrata. In flat Valley, mainly native species of Cornus controversa, Carpinus laxiflora are predicted ecological succession for deciduous broad-leaved tree community.
