국가중요농어업유산 의성 전통수리농업시스템 소류지의 식물상 및 분포 특성

Abstract

This study was conducted as a basic data for the management of the Uiseong Traditional Irrigation Agricultural System by identifying plant diversity and distribution characteristics. The total number of plant taxa was identified as 88 families, 250 genera, 368 species, 7 subspecies, 9 varieties and 384 taxa. In the case of life form, the domancy form was in the therophytes(th), the radicoid form was a R 5 (monophyte), the dis- seminule form was the gravity D 4 (having no special modification for dissemination), and the growth form wastheerectformwashigh.Thenumberofplanttaxabyland usetypewashigherinmountainoustypereser- voirsand plaintypereservoirsthan otherlandusetypes.Thedistribution ofplantsby land usetypeaccording tothehemerobygradewasplantation in thecaseof 3grade(meso-hemeroby) forests,and theunderstorywere mainly photophilic plants.

As for the number of plant taxa by reservoirs, the Wisgol pond in thecase of plain type reservoirs, Ungok pond was high in mountainous type reservoirs. The protected species were rare plants2 classification groups of Vulnerable(VU)species, 4 classification groupsof Least Concrned(LC) species, 1 classification group of Data Deficient(DD) species, 5 classification groups of Korean endemic plants, and 49 classification groups of invasive alien plants, and the total naturalization index was 12.2%.
