Abstract
To make conservative port and coast ecosystems and creative the greenspace, We were investigated with characteristic of flora, environmental factors, types of port, adaptive species, minimum conservation area and plantation model. In 50 sites of study areas, there are 19 families and 174 species of vascular plants and 19 families and 48 species of halophytes. Dominant communities in port ecosystem contains Carex kobomugi community, Elymus mollis community, Carex pumila community, Ixeris repens community, Vitex rutundifolia community, Calystegia soldandlla community, Rosa rugosa community, Lathyrus japonica community, Salsola komarovi community, Cynodon dactylon community, Tetragonia tetragonioides community, Suaeda japonica community, Suaeda maritima community, Zoysia sinica community and Phragmites communis community. We carried out Canonical Correspondence Analysis(CCA) for ordinations on the vegetation and plant communities-environmental variable matrices in 50 sites. The communities tended to cluster into three types: Clay marsh, Sand marsh, Sand gravel marsh types. Adaptive species in habitate types are selected that sand marsh-type communities in ports contained Elymus mollis community, Ixeris repens community, Carex kobomugi community, Carex pumila community, Clay marsh-type communities contained Suaeda japonica community, Phragmites communis community, Zoysia sinica community and Suaeda maritima community, Sand gravel marsh-type communities contained Vitex rutundifolia community, Calystegia soldandlla community. We are conducted the estimation of minimal area for plantation of adaptive plant species and carried out guide line and plantation model for creation of green space in port ecosystem.
항만생태계 녹색공간 창출을 위해 우리나라 항만에 분포하는 식물상특성, 환경요인분석, 항만유형분석, 적합종, 최소보존면적산출을 통해 식재모식도를 작성하였다. 50개 조사지역에서 44과 174종의 관속식물이 출현하였으며, 그중 염생식물은 19과 48종이 분포하였다. 우점군락은 통보리사초, 갯그령, 좀보리사초, 갯씀바귀, 순비기나무, 갯메꽃, 해당화, 갯완두, 솔장다리, 우산잔디, 번행초, 칠면초, 해홍나물, 갯잔디, 갈대를 포함하여 15개 군락이 분포하였다. 조사지역에 분포하는 식물군락과 환경요인과의 Canonical Correspondence Analysis(CCA) 결과 Clay marsh, Sand marsh, Sand gravel marsh 유형으로 분류되었다. 생육지 유형별 적합종으로 clay marsh는 칠면초, 갈대, 갯잔디, 해홍나물 sand marsh는 갯그령, 갯씀바귀, 통보리사초, 좀보리사초 sand gravel marsh는 갯메꽃, 순비기나무가 선정되었다. 적합종에 대한 최소보전면적을 산출하고 항만생태계 세부 유형별로 가이드라인과 모식도를 작성하였다.
