인공지반녹화지역인 서울로 7017 개원후 1년간의 이입식물 특성

Abstract

The purpose of this study is to provide basic data for the establishment of the management plan of Seoullo 7017 after analyzing the characteristics of immigration plants in addition to those introduced plants. The taxa number of plants appeared as 276 taxa including 82 families, 161 genera, 246 species, 1 subspecies, 22 varieties and 7 forms. Among them, immigration plants appeared 79 classification groups, including 32 families, 65 genera, 77 species and 2 varieties. Invasive alien plants appeared as 22 classification groups in 79 classification groups of immigration plants. The ratio of America origin plants, second period(1932~1960) in introduction time and the wide diffusion species is high. In June, the growth and occurrence time of the immigration plants was the highest by monthly the character- istics of the growth of the immigration plants, the immigration plants appeared mostly. In case of dor- mancy form among life-form, the therophytes(th), in the propagation form-radicoid form, the R 5 (monophyte), in the propagation form-disseminule form, the gravity D 4 (having no special mod- ification for dissemination), and in the growth form, the erect form(e) was high. The various immigra- tion plants appeared in green areas covered by Zoysia japonica and low Hedera helix densities. This study is the first flora study since Seoullo 7017 was opened in 2017. And so continuous flora monitor- ing is required for Seoullo 7017.
