中文摘要 | 經濟快速的發展,國人土地的需求轉趨迫切,層出不窮的坡地不當開發、利用,衍生出坡 地保育及水土保持問題,甚而頻頻造成災害,為保持坡地永續經營和恢復生機,應限制坡地的 土地利用在合理適宜的範圍,並加上適當的保育措施以降低災害發生,以達土地永續利用。 本研究以南投縣信義鄉人和村人和聚落為研究區域,人和部落由於邊坡較陡,在歷經頻傳 的天災重創下,造成不少災害,本研究擬以數值地形模型(DTM)為基礎,配合國土測繪中心、 水土保持保局之土地利用圖資,依相關法令劃定環境敏感區位。並分析其土地利用型態之變遷 趨勢,以為引導往後發展之參考。 研究顯示研究區面積約224.22 公頃,將各類敏感區位套疊,並加以累計得知區域內供公共 設施使用之類型土地均未位於敏感區位上,但由數據得知人和部落所在位置其敏感區位超過總 研究區面積67.91%,可知其環境較為敏感,其發展利用之限制亦較多。另以土地利用變遷檢 討對於水土保育功能之增減可知,其敏感區位分布主要仍以農業及森林為主。另將利用型歸為 趨勢遞增以及趨勢遞減二大類,再細部分析其利用型態為天然利用型(森林、草生地、荒地) 和人為利用型(農地、道路、公共設施地)兩組,綜合趨勢分析及細部分析,則主要變遷的利 用型態為以:農地、森林、荒、草生地及水利用地,由此四項利用型所組成的:「農地變森林」 及「荒、草生地變水利用地」,是為人和部落的兩大變遷。以水土保育觀之,此種土地利用變 遷應視為良性發展。 |
英文摘要 | Due to the rapid economic development, people demand for land has become more urgent. Inappropriate development in the slope land results in several problems of soil and water conservation and suffering disasters frequently. In order to maintain sustainable management and rehabilitation of life, a reasonable range should be specified for land use with appropriate conservation measures to reduce disasters. Zen-ho village, with steep terrain in Sinyi Township of Nantou County had been experienced frequent natural disasters and lots of calamities, was chosen as the study area. Digital terrain model (DTM) and land use maps derived from Land Use Investigation of Taiwan and Bureau of Soil and Water Conservation are applied to delineate the environmentally sensitive areas according to the related regulations. The changes of land use types were also analyzed for the references of guiding the ongoing development. The results show that the environmentally sensitive area, which although with no infrastructure in it and has occupied 67.91% of the study area, will limit the development of the village. The sensitive areas are mainly distributed at the sites of agriculture and/or forestry by using the land use changes to examine the variations of conservation functionality. Land use categories can be divided into trend-increasing and trend-decreasing types, and the utilization types can further be classified into natural utilization (forest, grassland, bare land) and human utilization (farmland, road, infrastructure). To synthesize both trend and detail analysis; farmland, forest, bare land, grassland, and hydraulic facility are the main changes of utilization. The changes of “farmland to forest” and “bare land or grassland to hydraulic facility” are the two types of utilization occurring in Zen-ho village. The changes can be regarded as a good development form the viewpoint of soil and water conservation. |
