Abstract

This study was supposed to offer vegetation plans for functional improvement of the recreational forest by researching Mt. Chukryong which is located at Oebang-li Sudong-Myon Namyangju Kyong-gi Province in Korea. In this study, artificial vegetation and natural vegetation near trails in recreational forest were researched through biodiversity analysis. From this analysis process, a typical management improvement of the biodiversity functions were examined by reviewing functions biotope condition, vegetation structure and wild bird community condition. Typical vegetation system was divided into four detail parts: Managed artificial Pinus koraiensis forest, Not managed artificial Pinus koraiensis forest, Natural deciduous forest and Not managed deciduous forest. As a result of the vegetation structure, the numerical value of the deciduous forest species diversity was higher than that of artificial Pinus koraiensis, and the numerical value of the managed condition was higher than that of not managed condition. As a result of a habitat structure analysis of the wild bird community, managed Pinus koraiensis forests were inadequate structure for wild birds to habit in there because the forests had weak structure layers, but unmanaged deciduous forest and unmanaged Pinus koraiensis that had diverse layers was proper places for birds to in habit. Thus, based on the functional analysis of biodiversity, management patterns of the target area were concluded in two manners: conserving management and restoring management. Deciduous forest protection target areas included natural deciduous forest area and managed deciduous forest area, ecological restoration target area included unmanaged artificial Pinus koraiensis area and restoring management target area includes managed artificial Pinus koraiensis.

본 연구는 휴양림의 기능 향상을 위한 식생관리 방안을 제시하고자 경기도 남양주시 수동면 외방리 축령산자연휴양림을 대상으로 실시하였다. 휴양림 내 등산로 및 산책로 주변의 주요 분포종인 잣나무 인공식생지와 자연식생지인 낙엽활엽수림의 생물다양성 조사 및 분석 등을 실시하여 휴양림 기능향상을 위해 식생유형별 관리를 위한 관리방안을 도출하였다. 연구방법은 생물다양성 측면에서 식생관리, 현존식생 및 비오톱 현황, 식생유형 구분, 식생구조, 야생조류 서식구조 등의 기능검토를 실시하였다. 휴양림내 식생유형 구분은 현존식생과 비오톱현황을 기초로 잣나무 인공조림지와 자연상태의 낙엽활엽수림으로 크게 구분할 수 있으며, 등산로 및 산책로 주변 대표식생 조림여부, 식생관리 등에 따라 4개의 유형(관리되지 않은 인공 잣나무림, 관리된 인공 잣나무림, 단풍나무 비율이 높은 자연상태의 낙엽활엽수림, 관리된 낙엽활엽수림)으로 구분하였다. 식생구조 분석결과 종다양도는 낙엽활엽수림이 인공 잣나무림 보다 종다양도가 높게 나타났고 관리되지 않은 상태가 관리된 상태보다 종다양도지수가 높게 나타남을 알 수 있었다. 야생조류 서식구조 분석결과 관리된 잣나무림은 층위구조가 빈약한 단층으로 식재되어 다양한 야생조류의 이동통로로서 부적합한 구조이고, 관리되지 않은 자연상태의 낙엽활엽수림, 잣나무림 등이 양호한 야생조류 서식구조를 가지고 있음을 알 수 있었다. 생물다양성 기능 검토에 근거하여 관리유형을 크게 보전관리와 복원관리로 구분할 수 있었다. 보전관리 중 기존낙엽활엽수림 유지유형은 자연상태의 낙엽활엽수림 지역, 관리된 낙엽활엽수림 지역 등이 속하며 생태적 관리유형은 관리되지 않은 인공 잣나무림 지역을 설정하였고, 복원관리지역인 생태적 복원유형은 관리된 인공 잣나무림 지역으로 설정하여 식생관리 유형별 관리방안을 제시하였다.
