우면산의 식생 연구

Plant community distribution, community change and species diversity in the Mt. Umyeon and its surrounding area were investigated from July to August 2012. The severe heavy rain caused landslides at several areas in the Mt. Umyeon in July 2011. We studied the effects of landslides on plant communities through comparative analysis with the former study before landslides. Dominant species were not changed significantly before and after 2011, although landslides had a great effect on some parts of Mt. Umyeon. The landslide reduced the number of trees and changed the community structure in some quadrats. On the other hand, it appeared that the succession process is ongoing on the both Quercus spp. and Robinia pseudo-acacia communities which were not affected by landslides into the Quercus mongolica community by the observation of the appearance of Quercus mongolica Fisch. in shrub, sub-tree, and tree layers. It seemed that Pinus koraiensis community would remain for quite a long time because the sub-tree layer has not attained its mature stage in community development.
