◇設計背景
1. 果實蠅每年造成台幣170億元農損: 雌蠅將卵產入果實內，幼蟲孵化後即在果實內鑽食，造成果實腐敗，可危害百種以上的寄主植物，危害率約 10 ～30%，嚴重影響
臺灣果樹產業的發展。
2. 蜻蜓在農業中具自然害蟲防治的重要作用: 蜻蜓以蠅類、小型飛蟲等為食，能有效控制害蟲族群，減少對農作物的危害。
3.蜻蜓因人為而消逝: 水泥護岸導致河岸兩側沒樹，水底鋪水泥，水流沒有緩衝，讓蜻蜓產卵和休息的枯枝落葉都被沖走了，就算少數的蜻蜓順利產卵，蜻蜓的卵和幼蟲也會被水流沖走。
◇設計理念
D.F.S蜻蜓庇護所提供蜻蜓在被人為破壞棲地後的庇護站和復育站。D.F.S蜻蜓庇護所可設立在水泥護岸中，其設計可減緩水流且可攔截河流中的落葉和種植植物以供蜻蜓產卵、產卵、庇護。蜻蜓於落葉聚集區產卵，卵孵化後幼蟲會順著水流進入幼蟲生長區進行生長，且幼蟲生長區中也可種植水生植物，讓蜻蜓直接將卵產於此。進入幼蟲生長區的縫隙較為細小，可有效防止大型的魚類進入，去捕食蜻蜓和其幼蟲，增加蜻蜓的生存率。
The D.F.S Dragonfly Sanctuary serves as a refuge and rehabilitation station for dragonflies whose habitats have been destroyed by human activities. It can be established within concrete riverbanks, featuring a design that slows water flow and intercepts fallen leaves from the river. Additionally, it supports plant growth, providing dragonflies with suitable environments for egg-laying, shelter, and reproduction.Dragonflies lay their eggs in the leaf accumulation area. Once hatched, the larvae follow the water flow into the larval growth zone, where aquatic plants can also be cultivated, allowing dragonflies to lay eggs directly in this area. The entrance to the larval growth zone is designed with narrow gaps to prevent large fish from entering and preying on dragonflies and their larvae, thereby increasing their survival rate.
