Abstract

To obtain the basic data for the conservation and cultivation of major native herb species under the trees, distribution of native herb species, and corrrlations between native herb species and site factors were studied on natural broadleaved forest in Mt. Gariwang and Mt. Jungwang, Pyeunchang-gun. 136 native herb species were distributed in studied area, and the importance percentage of Pseudostellaria heterophylla was proved the highest, 10.8%. The other major herb species were the following oders, Meehania urticifolia, Corydalis remota, Pimpinella brachycarpa, Carex siderosticta, Pseudostellaria palibiniana, Erythronium japonicum, Ligularia fischeri, Asarum heterotropoides var. mandshuricum, Hylomecon vernalis and Astilbe rubra var. rubra. Highly positive correlations were proved Hepatica asiatica and Ainsliaea acerifolia, Pimpinella brachycarpa and Aconitum jaluense subsp. jaluense, Aconitum jaluense subsp. jaluense and Smilacina japonica var. japonica, Meehania urticifolia and Pseudostellaria palibiniana. Seven groups of native herb species were divided by cluster analysis. Preferring site factors for each native herb species were determined. Ligularia fischeri, Ainsliaea acerifolia, Parasenecio auriculata var. matsumurana, Erythronium japonicum and Pimpinella brachycarpa were distributed mainly on the higher sites, Ligularia fischeri were ditributed more frequently in deep soil sites. These results might be useful measures in the conservation and cultivation of native edible and medicinal herb species on the forest floor in the natual broadleaved forest, Pyeungchang-gun.

자생 초본식물의 보존과 임간재배에 필요한 기초자료를 얻고자, 가리왕산과 중왕산 지역의 아고산대에 분포하는 천연활엽수림을 중심으로 주요 자생 초본식물의 분포와 입지인자를 조사하고 상호관련성을 분석하였다. 초본식물 분포조사에서는 136종의 초본식물이 확인되었으며, 개별꽃의 상대우점치가 10.8%로 가장 높게 나타났다. 그 밖에 주요 식물종은 벌깨덩굴, 현호색, 참나물, 대사초, 단풍취, 큰개별꽃, 얼레지, 곰취, 만주족도리풀, 피나물, 노루오줌 등 이었다. 노루귀와 단풍취; 참나물과 두메투구꽃; 두메투구꽃과 풀솜대; 벌깨덩굴과 큰개별꽃, 등의 종간에는 매우 높은 정의 상관이 인정되었다. 주요 식물종의 유집분석 결과, 7개의 그룹으로 나뉘어졌다. 주요 자원식물종이 선호하는 입지인자들이 밝혀졌다. 곰취, 단풍취, 박쥐나물, 얼레지, 참나물 등은 해발고가 높을수록 많이 분포하였고, 곰취는 토심이 깊을수록 많이 분포하는 것으로 나타났다. 얻어진 결과는 평창군 아고산 천연활엽수림의 보전과 주요 지원식물의 임간재배에 활용할 수 있을 것이라 사료된다.
