Abstract

To understand the vegetation structure in the ridgeline area of Nakdong-jeongmaek, six primary areas in Nakdong-jeongmaek were selected and their vegetation distribution was surveyed considering the environmental conditions and artificial influences. According to the results of community classification based on TWINSPAN, the vegetation in the surveyed region was categorized into 9 groups: Betula costata-Quercus mongolica community, Q. mongolica community, Pinus densiflora-Q. mongolica community, P. densiflora community, Deciduous oaks-P. densiflora community, Deciduous oaks community, P. thunbergii community, P. koraiensis-P. rigida community, and Chamaecyparis obtusa-Alnus firma community. In Baekbyeongsan(Mt.) located in Taebaek-si of Gangwon-do, Betula costata-Quercus mongolica community was found, reflecting the environmental characteristics of northern temperate climate. P. thunbergii community appeared in Gudeoksan(Mt.) of Busan metropolitan city, which is near the coast. Since Gudeoksan(Mt.) is near to the downtown and its altitude above the sea is relatively low, people visit the area often. Therefore, C. obtusa and P. thunbergii have been planted for producing forest trees and implementing anti-erosion afforestation. In the other primary survey areas, Q. mongolica-dominant communities, P. densiflora-dominant communities, and deciduous oak-dominant communities, which are representative forest vegetation types of Jeongmaeks in South Korea, were mainly distributed, showing no significant difference compared to the forest vegetation types of other Jeongmaeks. Since the Nakdong-jeongmaek from south to north, it shows clear characteristics of vegetation changes between the northern temperate climate and the warm temperate climate of the south.

강원도 태백시에서 부산광역시까지 이어지는 낙동정맥 마루금 일대의 식생상황을 파악하기 위해, 낙동정맥의 환경조건과 인위적 영향을 고려해 중점조사지 6곳을 선정해 식생조사를 실시했다. TWINSPAN에 의한 군락분류 결과, 거제수나무-신갈나무군락, 신갈나무군락, 소나무-신갈나무군락, 소나무군락, 낙엽성 참나무류-소나무군락, 낙엽성 참나무류군락, 곰솔림, 잣나무-리기다소나무림, 편백-사방오리림 등 9개로 유형화되었다. 강원도 태백시의 백병산에서는 온대북부 기후대의 환경특성을 반영한 거제수나무-신갈나무군락이 출현했고, 부산광역시의 구덕산은 해안에 인접한 지역으로 곰솔림이 분포했다. 구덕산은 도심에 위치해 있고 해발고도가 낮아 사람들이 자주 찾는 곳으로서 임목생산 및 사방녹화를 위한 편백, 곰솔 등과 조경수가 심어져 자연성이 낮은 편이었다. 그 외 중점조사지에서는 남한의 정맥을 대표하는 산림식생유형인 신갈나무우점군락, 소나무우점군락, 낙엽성 참나무류군락이 주로 분포해, 타 정맥과 산림식생유형이 크게 다르지 않았다. 낙동정맥은 남북방향으로 길게 늘어져 있어 온대북부 기후대부터 난온대 기후대까지의 식생변화가 뚜렷하게 나타난 것이 특징적이었다.
