AB - The purpose of this study is to construct ecological pond using LID technique in order to create naturally comfortable community space in urban idle space. The specification of the ecological pond is 110 m2 of surface area, 0.45±0.02 m of average depth, and bed material is composed of gravel (diameter ≤60 mm), sand (diameter ≤ 2 mm) and bentonite. Rainfall and water depth monitoring were conducted to determine the annual characteristics of inflow of the water for the ecological pond, result of total rainfall was 1,287 mm and showed a seasonal imbalance that accounted for 71.3% (918 mm) during July to August, but the annual mean water depth was kept constant at 0.45±0.02 m due to the secondary water source. Annual trends of basic water quality showed a significant changes according to the season, such as water temperature (5.2 ~ 28.8 °C), DO (5.0 ~ 13.8 mg/L), EC (113 ~ 265 μS/cm). BOD, COD, TN, and TP in physicochemical water quality tended to increase after October, but the ion parameters such as NH3 and PO4 3- were generally low. Phytoplankton indicators Chl-a and BGA (blue green algae) showed a sharp increase from July to August, and green algae (Selenastrum bibraianum, Pediastrum boryanum etc.) and filamentous blue green algae (Phormidium sp.) emerged as a dominant species. The ion parameters (F-, Na+, K+, Mg2+, Ca2+) were strongly correlated with the Cl- as a conservative substance (R=0.70~0.97, p<0.05). Water quality was influenced by the ambient environment such as seasonal changes or rainfall, and it was closely related to fluctuation of the inflow of the water. In the future, it is necessary to consider ecological connections by referring to the characteristics surveyed in this study in order to effectively manage the water quality and biodiversity of the ecological pond in idle space.
