Abstract

The study was carried out to offer the raw data on counterplan of restoration and conservation by systematical and objective analyzing the flora and herbaceous communities around Abeliophyllum distichum habitats. In the results of flora survey, as the site that the most taxa were showed was Yulji-ri, Geosan-gun III, there was surveyed as 114 ones; 48 families, 91 genera, 99 species and 15 varieties, and as Younjeong-ri, Jincheon-gun V was showed the fewest ones, there was appeared 54 ones; 28 families, 49 genera, 47 species and 7 varieties. The dominant species of herbaceous communities were verified Humulus japonicus${\cdot}$Artemisia princeps var. orientalis(Chujeom-ri, Goesan-gun I), Oplismenus undulatifolius(Songdeok-ri, Goesan-gun II and Maechon-ri, Yeongdong-eup IV), Carex siderosticta${\cdot}$Pueraria thunbergiana${\cdot}$Artemisia princeps var. orientalis(Yulji-ri, Geosan-gun III), Streptolirion cordifolium(Younjeong-ri, Jincheon-Eun V) and Sasa borealis(Junggye-ri, Buan-gun IV). In correlation analysis, Artemisia princeps var. orientalis${\cdot}$Carex siderosticta, Sasa borealis${\cdot}$Festuca ovina, Sasa borealis${\cdot}$Smilax china and Festuca ovina${\cdot}$Smilax china were showed the highest relativity. In similarity index analysis, as the site that was showed highest value was Yulji-ri, Geosan-gun III and Maechon-ri, Yeongdong-eup IV, there was turned up about some $27.27\%$. In the results of regression analysis between environmental factors and number of species, R-square of altitude and number of species was some $70.0\%$.

본 연구는 미선나무 자생지 주변의 식물상과 초본군락을 체계적이고 객관적으로 분석함으로써 자생지 복원 및 보전대책에 대한 기초자료 제공을 위해 수행되었다. 식물상 조사결과, 가장 많은 분류군을 보인 지역은 괴산군 율지리(III)로 48과 91속 99종 15변종 등 총 114분류군이 조사되었으며, 가장 적은 지역은 진천군 용정리(V)로 28과 49속 47종 7변종 등 총 54분류군이 출현하였다. 초본군락의 우점종은 환삼덩굴과 쑥(괴산군 추점리 I), 주름조개풀(괴산군 송덕리 II와 영동읍 매천리 IV), 대사초${\cdot}$칡${\cdot}$쑥(괴산군 율지리 III), 덩굴닭의장풀(진천군 용정리 V), 조릿대(부안군 중계리 VI)로 확인되었다. 상관관계분석 결과, 쑥과 대사초, 조릿대와 김의털, 조릿대와 청미래덩굴, 김의털과 청미래덩굴이 매우 높은 상관성을 보였다. 유사도지수 분석결과, 유사도지수가 가장 높은 것은 III과 VI지역으로 $27.27\%$를 보였다. 환경요인과 식물종수간의 회귀분석 결과, 해발고도와 식물종수의 설명력은 약 $70.0\%$였다.
