Abstract

This study was intended to suggest the appropriate vegetation management methodology by analyzing phytosociology for ecotourism resources. We carried out the classification and interpretation of the vegetation structure and the analysis of the relationship between communities and environmental conditions in Pocheon valley, Mt. Gaya. The vegetation in Pocheon valley was composed of 5 communities: Pinus densiflora-Quercus mongolica community, Quercus serrata-Quercus variabilis community, Larix kaempferi-Quercus serrata community, Pinus densiflora-Castanea crenata community, and Salix gracilistyla-Phragmites japonica community. The Quercus serrata-Quercus variabilis community was further segmented into two types according to the differences of composition species and location of habitats. The methodologies that satisfy both the use of nature for ecotourism resources and the sustentation of natural vegetation are as follows: - maintenance the present vegetation (dominance species) by strictly avoiding artificial management in the tree layer; - maintenance of the existing vegetation structure through the artificial management of the usual vigorous tree species when the species in the shrub layer grow up to the subtree layer; and - continued artificial management to maintain high balanced diversity and evenness of various species in shrub and herb layers.

본 연구는 가야산 포천 계곡의 생태관광 자원 활용을 목적으로 현존 환경요인과 군집유형의 관계를 식물사회학적으로 분석하여 적절한 식생 관리 방안을 제시하기 위해 수행하였다. 조사결과, 가야산 포천 계곡에서 다음과 같은 5개 유형의 군집이 조사되었다. 소나무-신갈나무군락, 졸참나무-굴참나무군락, 일본잎갈나무-졸참나무군락, 소나무-밤나무군락, 갯버들-달뿌리풀군락으로 나타났다. 졸참나무-굴참나무군락은 다시 조사지에 따라 2가지의 하위군락으로 나타났다. 조사지 식생을 대상으로 생태관광자원 활용과 건전한 자연식생 유지를 위해 다음과 같은 식생관리방안을 제안하는 바이다. 나타난 식물군집의 교목층에 대한 인위적인 관리는 철저히 배제하여 현존식생을 유지하도록 하며, 금후 시간 경과에 따라 관목층에서 생육하는 교목성 수종이 아교목층 이상으로 성장하였을 때, 숲 관리 등의 인위적 관리를 실시하여 기존 식생구조를 최대한 유지하도록 한다. 연구 대상지의 생물다양성을 높이기 위해 관목층 이하 층위에서 특정 종의 우점을 배제하고 다양한 식물종이 우점도를 유지할 수 있도록 인위적인 관리를 지속적으로 실시한다.
