영문 초록

In order to provide basic information for the design, operation and management of stormwater wetland for nonpoint pollution control, seasonal changes in soil properties of the reference wetland in the lower Nakdong river basin were analyzed for about two years. The reference wetland had morphological features that could increase the retention capacity due to deep water depth and long aspect ratio. Organic matter, total nitrogen and avaliable phosphorus concentrations were higher in growing season (GS) than in non growing season (NGS), but no significant differences were observed between them. It seems to be affected mainly by influent load of organic matter rather than the internal vegetation cycles. Soil pH was significantly higher in GS than in NGS, probably due to the consumption of the hydrogen ions during the reduction of nitrate and iron (III) ions under the reducing conditions. Cation exchange capacity concentration showed similar variation with pH, but no significant difference was observed between seasons. The activity of dehydrogenase was significantly higher in GS, presumably due to the abundance of organic matter in the soil layer and a favorable temperature environment for microbial activity. In future study, it will be necessary to include biogeochemical indicators such as C:N:P ratio and various extracellular enzyme activities in order to utilize the reference wetland for the developmental and functional evaluation of the stormwater wetland.
