Abstract
This study is carried out to offer raw data and establish strategy for conservation and restoration of river ecosystem by objective surveying and analysing the flora and vegetation distributed in Hwang river, Gyeongsangnam-do. The flora identified in this site were 406 taxa including 95 families, 252 genera, 360 species, 3 subspecies, 40 varieties and 3 forms. The rare plants were 3 taxa including Sagittaria sagittifolia subsp. leucopetala, Hydrocharis dubia and Acorus calamus. The endemic plants were 4 taxa including Populus tomentiglandulosa, Salix koriyanagi, Paulownia coreana and Weigela subsessilis. The specific plants by floristic region were 17 taxa including Salix siuzevii, Poncirus trifoliata, Potamogeton maackianus and so forth. The naturalized plants were 39 taxa including Phytolacca americana, Chenopodium glaucum, Lepidium virginicum, Oenothera erythrosepala, Xanthium canadense, Lolium multiflorum and so forth. The invasive alien plants were Ambrosia artemisiifolia and Ambrosia trifida. The whole NI and UI were each 9.6% and 13.9%. The hydrophytes were 27 taxa including Marsilea quadrifolia, Nymphaea tetragona, Ceratophyllum demersum, Trapa japonica and so forth. In the results of growth forms of the hydrophytes, emergent species were 14 taxa, 3 taxa of floating-leaved species, 4 taxa of free-floating species and 6 taxa of submerged species. The dominant vegetations were Salix spp. community, Miscanthus sacchariflorus community, Phragmites japonica community and Phragmites communis community.
