Plant Community Structure of Paekdam-Valley in Soraksan National Park
설악산국립공원 백담계곡 식물군집구조
Abstract
To investigate the plant community structure of Paekdam-Valley in Soraksan National Park, fifty-two plots have been set up and surveyed. By DCA ordination technique, the plant communities were classified into fkve community types, which were Pinus densiflora community and Q. mongolica community. It was supposed that Q. serrata community change to C. laxiflora community. It seemed that P. densiflora community, deciduous broad-leaved mixed forest and Q. serrata community would not be replace by another woody species. And it seemed that C. laxiflora community succeeded to Q. serrata community, so it was similar to the typical ecological succession of natural forest in the middle temperate regions. The range of Shannon's diversity index was 0.9827~1.2946(Unit area : 400m$^2$) and that was over another Korean National Parks area relatively.
설악산국립공원 내설악에 위치하는 백담계곡 산림의 식물군집구조를 분석하기 위해 52개 조사구를 설정하고 연구를 수행하였다. DCA 분석결과 소나무군집, 낙엽활엽수혼효림, 졸참나무군집, 서어나무군집, 신갈나무군집으로 분리되었다. 졸참나무군집은 서어나무군집으로 천이가 진행될 것이며, 소나무군집, 낙엽활엽수혼효림, 신갈나무군집은 그대로 유지될것으로 예측되었다. 온대북부림지역인 본 연구대상지의 서어나무군집은 졸참나무군집에서 천이가 진행된 것으로 추측되었는데 이는 온대중부림의 전형적인 생태적 천이경향과 유사하였다. Shannon의 종다양도 경우 0.9827~1.2946(단위면적: 400m$^2$)으로서 우리 나라 다른 국립공원지역보다 비교적 높았다.
