中文摘要 湖泊富營養化由養分積累驅動，改變了物種組成、食物鏈和養分循環。在福山生態池中，營養投入導致水生植物蓬勃發展，顯示水生植物正在轉向 優養化條件。這項研究於 2020 年 10 月進行，分析了水流、水質和營養濃度分析，以建造用於探索池塘中的養分儲存和流量的水和營養收支模式。結果結果顯示，福山生態池正在接近優養化狀態。水收支模式顯示，水容量變化為 2.95 m3 h-1，停留時間長達45.7天，說明水體交換不良。在營養收支模式中，61%的氮來自地表徑流，92%的磷輸入是由沉積物釋放的。沉水性植物Hydrilla verticillate 吸收了大部分氮，而 Spirogyra sp. 吸收了大部分磷。氮和磷收支模式顯示 0.100 g N h-1 和 0.437 g P h-1 正在池塘中積累。總的來說，這項研究顯示未來的管理應著重於減少進水口氮輸入，在進水口安裝簡易人工濕地來淨化進入池塘的水質。為了減少養分積累，管理上應通過人工濕地減少營養輸入，以及防止沉積物擾動以限制磷的釋放。這些行動將有助於減輕營養物質在池塘中的持續積累，改善其生態條件和功能。
英文摘要 Eutrophication, driven by nutrient accumulation, alters species composition, food chains, and nutrient cycling in aquatic ecosystems. In the Fushan Ecological Pond, nutrient inputs have led to flourishing aquatic plants, indicating a shift towards eutrophic conditions. This study conducted in October 2020 analyzed water flow, quality, and nutrient concentrations to construct water and nutrient budgets for exploring nutrient stocks and flows in the pond. The results show that the Fushan Ecological Pond was approaching eutrophic condition. The water budget shows that the change of water capacity was 2.95 m3 h-1, and the residence time was as long as 45.7 days, indicating that the water body was poorly flushed. In the nutrient budget, 61% of nitrogen came from the surface runoff, and 92% of the phosphorus input was contributed by the release from sediment. The submerged plant Hydrilla verticillate absorbed most of the nitrogen, and Spirogyra sp. absorbed most of the phosphorus. The nitrogen and phosphorus budgets show that 0.100 g N h-1 and 0.437 g P h-1 were accumulating in the pond. Collectively, this study suggests that future management efforts should focus on reducing N input from the inlets by installing simple constructed wetlands at the inlets to purify the water entering the pond. To mitigate nutrient accumulation, management should reduce nitrogen input via constructed wetlands and prevent sediment disturbance to limit phosphorus release. These actions would help mitigate the ongoing accumulation of nutrients in the pond and improve its ecological condition and function.
