將農業寄生轉變至環境共生的水紋地景

水是滋養大地的母體,農業生產最重要的元素,而雲林是台灣的農業重鎮 。諷刺的是目前在雲林地區,因降雨季節性的差異使得水資源分配不均, 以往依賴的水源只能由地下水替補,使地層下陷更加嚴重。農業廢水、生活汙水皆直接放流,在水資源的使用上雲林早已失衡。我們利用地景設計, 將水收集、淨化、儲存再利用,增加水資源的循環利用,為托舉土地帶來一絲希望。 Water is a vital element for the earth and agriculture. Yunlin is the most important argricutural city for Taiwan. However, now in Yunlin area, because of the seasonal rainfalling the water once farmers relyied on must be replaced by groundwater.In this circumstance, the condition of land subsidence is getting worse. The agricultural water wastes discharge directly into the ocean. The use of water has reached a huge imbalance .So we are using landscape design to gather, purify and supply the short of water in order to push the water ciculation and bring hope to the ground.
基地分析 Site Analysis
基地位於高鐵沿線地區,因超抽地下水情況嚴重,直接影響途經雲林的 高鐵安全,「黃金廊道計畫」應運而生。 基地上游有足夠面積的農田及村落可以提供廢水,利用上游的水道和基 地周邊原有的舊水圳,將原本直接流入大海的農業廢水及生活用水收集。 基地東西落差為四公尺,運用現有的高差條件,讓水以自然方式流動。 基地西南側有大片原生林,利用茂密的樹林作為天然的儲水基地,減少 蒸散量。 基地周邊被廢棄的舊水圳環繞,利用舊水圳做為水的新通道,進行引水 和排水。 Our base is located at Yunlin area. Because of the groundwater overdrafting, which may threaten the safety of the HSR,
the golden
way plan comes up. The upstream area has plenty of farmlands to produce agricultural wastes. The drainage channels and old waterways around the site make it possible to gather the water which are probably flow straight into ocean. Using the natural elevation to flow the water. This site is surrounded by a abandoned drainage channel. Use that channel to let the stream in and out.
