초록

도시화의 과정에서 고립도어 버린 쉬나무군락(Evodia daniellii community)의 현존 색생도, 군락의 구성과 식생구조를 조사하였다. 수도산 동사면의 벼랑에 서식하고 있는 쉬나무군락 지역에 100m$^{2}$의 측구를 30개 설치하였고, 계적넉인 변이를 보정하기 위하여 전 생육기간 동안 15회 현지조사를 수행하여 종조성표를 작성하였다. 이틀 자료에 의한 $x^2$ 계산값으로 constellation을 작성한 결과 Albizzia julbrissin 외 10종, Zanthoxylum shinifolium 외 12종 그리고 Ulmus parvifolia 외 6종의 명확한 3개 종군으로 구분되었다. 주요 목본식물 5종의 흉고직경을 조사한 결과 흉고직경의 크기가 상대적으로 큰 Ailathus altissima, Paulownia tomentosa, Zelkova serrata가 현재의 우점종으로 출현하나 후계림은 분폭역이 가장 넓ㅅ은 Evadia daniellii가 차지할 것으로 보인다.

The actual vegetation map, community composition and vegetation structure of an isolated Evodia daniellii community due to the urbanization were investigated. At the habitat of Evodia daniellii, east cliff of Mt. Sudo, I made 30 plots of 100m$^{2}$ and adjusted 15 times the aspect of vegetation in whole growing season. On the base of these data, synoptic vegetation table was constructed. The constellation diagram by the calculation of ${\chi}$$^{2}$-value based on the vegetation data shown three vegetation groups pf Albizzia julibrissin with 10 species, Zanthoxylum shinifolium with 12 species and Ulmus parvifolia with 6 species. Through the DBH measurement of 5 major tress, we found that Ailanthus altissima, Paulownia tomentosa and Zelkova serrata are dominant in present, but it will be change by Evodia daniellii.
