中文摘要 | 本研究以南仁山生態保護區為例,應用航測與地理資訊系統技術,結合傳統生態學之定量表示方法,探討地景異質性之演變過程。採用1976與1997年之航空照片為材料,判釋出9種土地利用型,並繪製成1/5,000之向量式圖層。為利於地景類型之分析,則以像片基本圖為基礎,將研究區劃分為15個樣區,並繪製地景優勢度之網格式分布圖,再利用相對優勢度與相對頻度,分別探討各樣區地景類型之變異,結果顯示南仁山森林生態系之演替已趨於穩定之現象。除此之外,本研究結果亦可提供生物多樣性相關研究之參考資訊,進而促進國家自然保育與永續發展之規劃。 |
英文摘要 | This paper presents a case study of changes in landscape heterogeneity of Taiwan conducted at the Nanjen Mountain Ecological Reserve. The techniques of photogrammetry, geographic information system (GIS), and traditional ecology analyses were used. According to the aerial photographs (1/5,000) of 1976 and 1997, the study area was divided into 15 plots, and landscape patterns were identified with nine land-use categories. For each plot a distribution of landscape patterns was established with a grid map, and relative dominance and relative frequency of land use categories were calculated. The result of this study suggested that the forest ecosystem succession is stable at the Nanjen Mountain Ecological Reserve. It also provided information useful for biodiversity related studies, natural conservation, and sustainable development of Taiwan. |
