植群圖可以顯示出某一地區之植群類型及其空間分佈與面積，不僅是基礎的生態資料，也有助於瞭解植群分佈與環境之相關性。本研究依據「國家植群多樣性調查及製圖計畫」之植群分類標準，以航照及衛星影像繪製陽明山國家公園之植群分佈圖，並以GIS分析保護區現況，以及植群分佈與環境因子之關係。結果顯示陽明山國家公園植群以常綠闊葉林爲主，特色植群則包括箭竹及草生地，但亦有耕地、建地等人爲干擾。生態保護區內人爲干擾很小，對於植群具有核心保護成效。國家公園內植群及土地利用分佈受到環境因子影響，人爲開發多集中在低海拔、平坦、河川周圍和背風地區，而箭竹、草生地等則多分佈於高海拔、陡坡、迎風地區。
Vegetation maps not only show the vegetation formations of an area, but also provide information about vegetation distribution and sizes. Therefore, vegetation maps are considered as a basic ecological data, and are useful for analyzing relationships between vegetation and environment. This study used aerial photographs and satellite imageries to map the vegetation distribution of the Yangminshan National Park according to the vegetation classification protocols specified by the National Vegetation Diversity Inventory and Mapping Project. GIS was used to evaluate the effectiveness of protected areas, and to analyze the relationship between land covers and environmental factors. Results showed that evergreen broadleaf forests dominate the Yangminshan National Park. Other characteristic vegetation formations include arrow bamboo bushes and grasslands. Nevertheless, human disturbances such as farmlands and developed areas also exist. Protected areas, which have very minor human disturbances, have effectively preserved parts of the characteristic vegetation formations as protection cores. Vegetation formations and land used were affected by environmental factors. Developed areas generally located at flat leeward areas at lower elevation adjacent to rivers. Arrow bamboo bushes and grasslands, on the other hand, often located at windward areas with high elevations and steep slopes.
