Abstract
在台灣獨特的山坡地地形特徵以及氣候變 遷的影響之下,台灣的坡地面臨越來越高 風險的可能性,包含土砂災情、土砂汙染 民生的用水等等。 然而原住民卻是面臨坡地風險首當其衝的 族群,因原住民保留區大多被劃設於山坡 地範圍之內,牠們的生命安全以及居住的 基本權利都逐漸暴露於風險之中;另外台 灣相關坡地法規對於原住民族的限制使得 他們開始懷疑自身的土地價值,開始拋售 土地轉租、拍賣給平地人來開發山林開發 出時下熱門的觀光休閒產業;然而這樣的 行為轉移模式導致的是台灣山林的裸露, 再加上氣候變遷加劇的影響,台灣的坡地 逐漸面對越來越險峻的危機。 故我們希望能夠透過規劃設計有效的處理 坡地保水的機能,以及減緩坡地土砂災害 的可能性,達到永續坡地社區的願景。

Over the years surface exposed situation 水田部落自從 2006~2010 開始地表裸露面積逐漸擴大,主要原因是農地種植薑、高 麗菜等經濟作物;而至 2013 年開始地表裸露狀態逐漸減緩,其主因是因為當地民 眾向政府舉報即及新聞媒體的報導使不肖業者減緩經濟作物的種植,但卻在 2015 年開始地表裸露狀態又開始惡化。

Slaq’s Village 新樂村水田部落,位處尖石鄉西北方,北與新竹縣關西鎮錦山里馬 武督部落相接,東與桃園縣復興鄉高義部落為鄰,西邊為嘉樂村, 南邊則是新樂村的煤源、八五山一帶部落。Slaq 在泰雅語中,既有 水田,也有混濁、泥濘的意思,反映出水田部落由尖石鄉不同部落 混居的特色。

樹的結構能在大自然中屹立不搖 的存在千年以上,故我們去研究 樹木的結構從樹冠、樹幹再到樹 根的結構,了解到樹冠在承受降 雨時能有效減緩對地表的沖蝕; 樹幹則是支撐的結構本體;最後 在樹根的部分則負責穩固土讓防 止土砂流動。藉由上述的仿生學 研究,將會是我們在往後規劃設 計時會參考學對象。

Basic information on crops 依照左表可以看到水田部落內 所種植的農作物狀況,包含作 物的用水量、日照程度、澆灌 的方式以及作物的播種、收成 的季節月份,從做農作物的收 成狀況來看作物生成狀況主要 分布於夏、秋、冬三季。 然而農作物種植會消耗土壤裡 的養分以及有機物質,我們將 農作物以消耗土地程度分高、 中、低,再去就其土讓需要恢 復時間做比較,發現有的作物 需要恢復土地養分時間長達 4 年以上,故這段時間我們在想 能否以一種新的土地使用型態 來填補這段時間的空缺,並防 止水田部落裸露地表面積增加 的可能性。

Plants planting idea 在我們的設計單元之中,分為邊緣及核心兩個層面且分別會有不同的空間穿 越性,包含人的活動、動物的廊道,我們將這兩個層次搭配上基地上的活動 使用,包含農業、露營 ( 小家庭 )、露營 ( 大家庭 )、農業露營混和以及滯洪 池等,因此這些因素都會決定我們搭配植栽的種類,不同的種類配置在 " 邊 緣 " 以及 " 核心 " 會有不同的植栽效果,來達到水土保持的最佳效益。
