Abstract
This study was conducted to investigate the effects of adjacent stand on the invasion of Robinia pseudoacacia plantations. The results were as follows. 1) Robinia pseudoacacia tended to invade into all directions regardless of the kinds of adjacent stands. But it was estimated that the invasion of Robinia pseudoacacia into adjacent stands could be very difficult, if the layer structure of adjacent stands were well developed. Whereas, it was estimated that Robinia pseudoacacia more rapidly intruded into adjacent stands, if adjacent stands were opened and bared. 2) Robinia pseudoacacia tended to invade into all aspects regardless of the kinds of vegetation units in the adjacent stands. But the dominance class of Robinia pseudoacacia in the adjacent stands showed a little differences among the vegetation units. The dominance class of Robinia pseudoacacia in Quercus aliena community and Quercus serrata community showed low level as + ~2, while the dominance class of Pinus densiflora community, Pinus rigida community, Quercus variabilis community and Quercus acutissima community represented high level as 1~4. Also the dominance class of Isodon inflexus subgroup among three subgroups of Pinus densiflora community showed the lowest level as + ~2.
아까시나무가 인접 임분의 종류와 계층구조 그리고 식생단위에 따른 이입 정도를 분석하였던 바 다음과 같이 요약할 수 있었다. 1) 인접 임분의 종류에 관계없이 전 방위로 아까시나무가 이입하고 있었다. 그러나 계층구조가 잘 발달된 임분에는 이입하기 어려우나 임분이 소개되었거나 아까시나무가 재해를 입었을 경우에는 인접 임분 내에 빠르게 이입할 것으로 예측되었다. 2) 아까시나무는 인접 임분의 식생단위에 관계없이 전 방위로 이입하고 있으나, 식생단위 간에 차이가 있었다. 갈참나무군락과 졸참나무군락 내에서는 아까시나무의 우점도가 +~2로서 낮게 나타났으며, 소나무군락, 리기다소나무군락, 굴참나무군락 및 상수리나무군락에서는 아까시나무의 우정도가 1~4로서 높게 나타나는 경향이 있었다. 소나무군락 내의 3개 식생단위 중에서는 산박하소군(I-A-1)에서 아까시나무의 우점도가 + ~2로서 가장 낮게 출현하였다.
