Abstract
The forest vegetation in Daedeok Science Town were classified as second forest vegetation and afforestation vegetation. The second forest vegetation was classified into two communities such as Pinus densiflora community and Quercus acutissima community. Also, the afforestation vegetation was classified again as Robinia pseudoacacia community, Pinus rigida community, Pinus thunbergii community, and Castanea crenata community. In this study area, we found total 217 taxa. The average species of appearance in Pinus densiflora community, Quercus acutissima community, Robinia pseudoacacia community, Pinus rigida community, Pinus thunbergii community, and Castanea crenata community were 21, 20, 20, 21, 21, and 18, respectively. There was no difference in appearance species between second forest and afforestation vegetation. We found total 12 naturalized plants taxa of Commelina communis, Phytolacca americana, Erigeron annuus, and Ailanthus altissima in the plots and total 19 naturalized plants taxa of Dactylis glomerata, Bidens frondosa, Xanthium strumarium, and Soianum nigrum in the climbing roads and forest circumferences. And so, we found total 31 naturalized plants taxa in this study area.
대덕연구단지의 산림식생은 이차림식생과 조림식생으로 구분되었다. 이차림식생은 소나무군락(Pinus densiflora community)과 상수리나무군락(Quercus acutissima community)으로, 조림식생은 아까시나무군락(Robinia pseudoacacia community), 리기다소나무군락(Pinus rigida community), 곰솔군락(Pinus thunbergii community), 밤나무군락(Castanea crenata community)으로 구분되었다. 본 조사지역에서 출현한 종수는 총 217종이었으며, 각 군락별 평균 출현종수는 소나무군락이 21종, 상수리나무군락 20종, 아까시나무군락 20종, 리기다소나무군락 21종, 곰솔군락 21종, 밤나무군락 18종으로 밤나무군락에서 출현종이 가장 적었고, 이차림군락과 조림군락 간에는 차이가 없었다. 귀화식물은 조사구내에서 닭의장풀, 미국자리공, 개망초, 가중나무 등 12종이 출현하였고, 등산로와 산림주변부에서는 오리새, 미국가막사리, 도꼬마리, 까마중 등 19종이 출현하여 총31종의 귀화식물이 조사되었다.
