서울시청 옥상정원 "초록뜰" 모니터링을 통한 식재식물과 이입식물의 관리방안에 관한 연구

The management methods of rooftop greening must be get ready without delay, Because rooftop greening has been generalized owing to the supporting project of The Seoul Metropolitan Government. Because most of the rooftop greening system is a recently-constructed low-management type, management methods should be made to suit it. This study is intended to set up a program for low-management rooftop greening based on `Choroktteul`, the low management type of rooftop greening on the roof of one of the buildings in Seoul City Hall.<BR> Through monitoring, we found that most of the planted plants grew well but a few species needed physical management. We also found that invasive species(62 sp.) were 1.5 times as many as the planted plants. Most of the invasive plants were exotic species that need to be managed. The physical management methods were `pulling up` and` cutting`. These methods should be carried out according to the growth stage. It was judged that a biological-ecologicaJ management program should be prepared through the long-period of monitoring and experiment. System methods such as guidelines of management program through monitoring was also required due to the emphasis on public ownership among the managers of the invasive species.
