1977年蔗紙興起,後因嚴重工業廢棄物及廢水汙染,1994年紙漿廠正式關閉,留下殺蛇溪二岸近八十公頃閒置荒蕪的土地。
2013年,屏東縣政府啟動屏東平原水嫷香蓮根計畫,並以萬年溪及殺蛇溪為主軸,向外延伸八大主題計畫——水與綠家園計畫,其中包括重組殺蛇溪河廊綠地之公共開放空間。
2020年破繭新生,保留工業地景及遺構,營造綠水公園及水岸生活圈,亦運用保存、活化、再運用(Adaptive Reuse)的觀念,整合地景、文化產業及水環境特質並以完成地域建築的實踐。
設計重點之一,包括既有遺構保存再利用及廠區空間紋理再深化,檢視老廠區地圖,了解地上物及地表下可能之結構物位置,完成地坑等重要遺構之地下構造物繪製。整理了出土的遺構,印證紙漿廠的營運作業及管理路線,並勾勒出相對性空間及造型架構。由大型紙漿廠倉庫沿著殺蛇溪左右岸出土了三座地坑(面積約1,019平方公尺)及五座水池(面積約3,979平方公尺),五分車軌道、管道橋、五分車板橋及碉堡等遺構,沿著經過二座退堤及降堤水岸親水環境之形塑,勾勒出跨時空座標的歷史漫遊路徑及後紙漿廠工業地景語彙通道。三座地坑空間並未連結且地坪高程不均,最高有六公尺深度,因而設計降挖之中央中庭及周邊地形形成三座地坑間之動線連結及高程轉換,並配合殺蛇溪的退堤設計滿足未來洪峰時期滯洪池之功能。
地坑牆面盡量維持原狀原貌,包括色澤、質感及材料層次的表現,在部分牆面結構需補強之部分,運用不同造型耐候鋼板作為媒介,除滿足安全機能外,並連結新與舊不同層次之視覺效果。
五座水池遺構大小不一卻具相同之結構形式,在不破壞原有造型的原則,引入及設置不同休憩、舞台劇場、展演及運動等戶外空間機能。在地景造型上,五座水池整體上表現出特殊的幾何地形,營造序列性的地景變化。
設計重點之二,延續殺蛇溪截流井設置、水質改進及淤泥清除等工程後,更積極企圖恢復紙漿廠興建前的順應地形,及具有滯洪功能且呈現尊重自然生態環境的水域廊道。在整體設計的概念下,採取二座退堤及降堤之手法,更創造親水及近水的空間,並依據防汛考量,設置約5,882平方公尺供滯洪用途的水域,在低水位期可透過低階濕地去提供多元物種之棲地,並在鄰近低水位的溼地種植如野薑花和莎草等水生植物,做為屏東生態環境示範指標之場域。
Sugarcane paper production began in 1977 in Pintung. The pulp mills were subsequently closed in 1994 due to serious industrial waste and wastewater pollution, leaving nearly 80 hectares of unused land along both banks of the Shashe River.
In 2013, The Pingtung County Government launched the Pingtung Plain Shuituoxiang Lotus Root Project. The Wannian and the Shashe Rivers were the main areas of focus with eight themed projects, the so-called Water and Green Homes Projects. These included the reorganization of public open areas and green spaces along the river corridor of Shashe River.
In 2020, there was a revival to preserve the industrial landscape and heritage of the region with the creation of green water parks and waterfront living circles. The design methods of preservation, activation and adaptive reuse were incorporated. This would integrate the landscape, the cultural industry and the aquatic environment with the intention of creating a regional architecture.
The first key feature of the design is the preservation and reuse of existing structures, thus animating the industrial spatial experiences of the old factory areas. By studying existing maps of the old factory areas, a better understanding of the locations of ground objects and possible structures under the ground is achieved. With this understanding, new drawings of underground structures such as pits and other important structures can be completed. Unearthed remains were sorted out. They help verify the operation and management routes of the pulp mill. The relative spatial and structural relationships were outlined. Three pits (with the area of about 1,019 m2), five pools (with the area of about 3,979 m2), half-size train tracks, pipeline bridges, half-size train slab bridges, bunkers and other relics were excavated from the warehouses of the pulp mill. The design involved the creation of a hydrophilic environment that passes through the two retreats and lifts along the water bank. This allowed the roaming paths of history to cut across the coordinates of space and time creating a series of post- industrial landscape elements.
The spaces between the existing three pits were not connected due to the uneven floor elevation with a maximum height differential of six meters. Therefore, the excavation of the central atrium and the surrounding terrain were designed as connections and transition points between the three pits. Furthermore they act as retention ponds along the embankment of the Shashe River assisting in future flood management.
The existing finishes of the pit walls are left in the original state as much as possible, allowing preservation of the original color, texture, and materiality. Thick steel plates of different shapes were used in some parts of the wall as structural reinforcement. The steel plates fulfilled not only a safety requirement, but they provided visual connections between the new and the old.
The remaining five pools are of different sizes but the same structural form. In concert with preserving the original shapes, different outdoor spaces for recreation, theatrical performances and sports have been introduced and installed. The five pools show a special geometric topography as a whole, creating a sequence of landscape changes.
The second key feature of the design is the installation of interception wells continuing the water quality improvement and silt removal projects of the Shashe River. The goal is to return the water corridor to its original state prior to the construction of the pulp mill. The terrain will conform to its natural ecology and flood detention function. As outlined by our overall design, the existing embankments were pushed back and lowered, creating a more hydrophilic and water friendly environment. Given due consideration to flood control, a water retention area of approximately 5,882 m2 was set up providing habitats of multiple species in the terraced wetlands. Aquatic plants, wild ginger flowers and sedges, were planted in the adjacent low-water wetlands. These would act as ecological demonstration zones for the Pingtung region.
