초록

The purpose of this study was to present the ecologically important data for conservation and management of river ecosystem. Namcheon Stream, the study site, is a local river flowing from the east to the west of Gyeongju. The results are as follows. The numbers of vascular plants were summarized as 518 taxa including 98 families, 321 genera, 467 species, 9 subspecies, 32 varieties, 4 forms, 4 hybrids and 2 cultivars. The rare plants were 4 taxa including Aristolochia contorta, Koelreuteria paniculata, Hydrocharis dubia and Sparganium stoloniferum. The Korean endemic plants were Populus × tomentiglandulosa, Salix koriyanagi, Lespedeza maritima, Weigela subsessilis and Hemerocallis hakuunensis. The floristic target species were 27 taxa including 2 taxa of grade IV, 4 taxa of grade III, 7 taxa of grade II and 14 taxa of grade I. The invasive alien plants were 92 taxa including Pterocarya stenoptera, Conyza canadensis, Vulpia myuros and so on. The ecosystem disturbing species were 6 taxa including Rumex acetosella, Sicyos angulatus, Solanum carolinense, Ambrosia artemisiifolia, Lactuca seriola and Symphyotrichum pilosum.
