Abstract

상록활엽수림의 복원 사업에 대한 모니터링을 시행하여 상록활엽수림 복원기술개발을 위한 기초자료를 제공하기 위하여 다도해해상국립공원에서 시행한 상록활엽수림 복원 사업을 2005년부터 3년간 모니터링하였다. 5개 시범녹화시험지에서 사면, 섬 크기, 방사가축의 유 무에 따른 생장량과 활착률을 모니터링하였다. 남서사면 능선부에 식재한 상록활엽수의 수고 생장량과 활착률이 북동사면 능선부에 식재한 상록활엽수보다 더 양호하였다. 큰 섬에서 상록활엽수의 활착률이 작은섬보다 높게 나타났다. 방사가축이 있는 곳의 상록활엽수 활착률이 방사가축이 없는 곳보다 매우 낮게 나타났다. 남서사면능선부, 큰섬, 방사가축이 없는 곳에서 상록활엽수림의 생장량과 활착률이 높게 나타났다.

English Abstract

To offer basic data for restoration technology development of the evergreen broad-leaved forest, this researcher did monitoring on the restoration project of the evergreen broad-leaved forest implemented in Dadohaesang(Marine) National Park for three years starting the year 2005, As a result of the monitoring job of tree height and survival rate of the evergreen broad-leaved forest on the 5 model afforestation-testing sites subsequent to the slanting surface, size of island, and whether the pastured livestock exist or not, it was found that the tree height & survival rate of the evergreen broad-leaved trees planted on the ridge parts of the southwest slanting surface were in better condition than those of the evergreen broad-leaved trees planted on the ridge parts of the northeast slanting surface. The survival rate of the evergreen broad-leaved tree planted on a big island was revealed to be higher than that of the evergreen broad-leaved tree planted on a small island. In addition, the survival rate of the evergreen broad-leaved tree planted in a place where livestock was pastured was revealed to be much lower than that of the evergreen broad-leaved tree planted in a place where there was no livestock. Conclusively, there showed a good tree hight and survival rate of the evergreen broad-leaved tree planted on the ridge parts of the southwest slanting surface, on a big island, and at the place where there was no pastured livestock.
