Abstract

This study was conducted to provide data for the maintenance of the Corylopsis coreana community within the Hallyeohaesang National Park. Survey site of Corylopsis coreana community was located at a valley, which composed of over 60% exposed rock. As this result, much of the species was damaged or washed away due to the water flow from rainfall. The tree layers dominant species were Quercus serrata and Pinus densiflora. while the subtree layers dominant species were Corylopsis coreana, Acer pseudosieboldianum, Sapium japonicum, Chamaecyparis obtusa and Cornus kousa etc. The shrub layers dominant species were Callicarpa japonica and Smilax china etc., and herbaceous layers dominant species were Disporum smilacinum etc. Increased precipitation and rainfall days were observed from May to September in this valley during 2008~2010, which likely increased soil erosion and damage. Because water flow pattern was dispersed the Corylopsis coreana seed and the soil floor was shallow, and population of Corylopsis coreana seedlings were diminished.

본 연구는 한려해상국립공원 특별보호구로 지정된 히어리군락의 생육상태와 향후 자생지의 지속적인 보전 및 관리를 위한 기초자료로 활용하고자 분석하였다. 히어리군락은 계곡부에 위치하고 있었으며, 암 및 자갈 노출도가 60%이상으로 식피율이 낮게 나타났고 계곡범람으로 조사구의 훼손과 교란현상이 나타나고 있었다. 히어리군락의 교목층은 졸참나무와 소나무가 우점하였으며, 아교목층은 히어리, 당단풍, 사람주나무, 편백, 산딸나무가 우점하였다. 관목층은 작살나무, 청미래덩굴 등이 우점하였으며, 초본층은 애기나리 등이 우점하였다. 계곡부에 위치한 히어리군락의 3년동안(2008~2010년) 생육기인 5~9월의 강수량 및 강우일수는 점차 증가하여 침식 및 훼손 등의 교란가능성이 높았으며 히어리가 주로 수광량이 높은 계곡부에 분포함으로서 성숙된 종자의 산포가 토양층이 얕은 계곡으로 분산되어 유묘 발생에 의한 개체군 증가가 빈약하였다.
