초록
Green spaces in cities were insufficient and decreased as artificial structures increase. Accordingly, greening rooftop space contributed to urban ecosystems as green space. Especially, since 2002 Seoul supported rooftop greening and introduced 'Ecology-area rates'. Thus rooftop greening had the potentiality of extension. This prepared the extensive rooftop greenings within planting-base for extensive management rooftop greening system to be easily popularized. The extensive rooftop greening conducted from 1997-2005 reported that soil depth was 8cm and soil mixtures were 5 types. And plant were Crysanthemum zawaskii var. latilobum, Aster hayatae, Crysanthemum zawaskii herb. ssp. coreanum, Sedum sarmentosum, Sedum rotundifolium, Sedum oryzifolium, Sedum takemensis, Sedum middendorffianum, Sedum telerium var. purpureum, Sedum spectabile, Carypteris incana, Dianthus superbus, Hosta minor. As a result, for nine years after the modular type rooftop greening established, survival plants were Sedum takemensis, Sedum sarmentosum, Sedum spectabile, Sedum middendorffianum, Carypteris incana, Crysanthemum zawaskii var. latilobum, Sedum telerium var. purpureum, Sedum rotundifolium, Dianthus superbus. Also effect of greening was possibled soil depth 8cm. And growth of plants from 1997 to 2005 were fine on two soil mixtures of 'perlite+peatmoss+vermicompost+moisturizer' and 'perlite+moisturizer+bark(mulching)'. Invasive plants are Ixeris dentata Nakai, Ixeris chinensis var. strigosa, Youngia sonchifolia, Eragrostis ferruginea, Aster pilosus Willd., Ixeris japonica Nakai, Valpia myuros, and Setaria viridis. In conclusion, selection of suitable native plants was possible extensive management rooftop greening with effect of continuous greening. The extensive rooftop greening were lightweight and simple preparation without management and can popularize readily.
