To understand the relationship between fossil pollen and ancient vegetation, we have to study their modern analog, the pollen in surface soil and the modern vegetation. 　　Fifty surface pollen samples from Yangmingshan National Park are analyzed using the cluster analysis method in this study. They are grouped into different vegetation types according to their components of the pollen sum. The differences between pollen taxa and vegetation taxa are also discussed. The fifty samples can be grouped into two categories, grassland and forest. The grassland is dominant by Poaceae. The forest includes Cryptomeria plantation and some natural vegetation. Other samples not belong to grassland or forest are collected from the transition zone. The present results agree with the reported vegetation classifications which were obtained by vegetation investigation. This indicates that although the vegetation types in the park have a mosaic pattern, the surface pollen can still reflect the vegetation types. The pollen data and some geographic factors are also analyzed by the method of detrended correspondence analysis (DCA). The results reveal that among altitude, aspect and slope, the altitude is the most important factor affecting pollen distribution.摘要 (ii) Abstract (iii) 壹、緒論 (1) 　一、相關研究概況 (2) 　二、本研究緣起 (3) 貳、材料與方法 (6) 　一、前置作業 (6) 　二、採樣方法 (6) 　三、樣本處理與分析 (6) 　　(一) 樣本處理 (6) 　　(二) 孢粉鑑定與計數 (7) 　　(三) 採樣點地理資訊 (8) 　　(四) 資料統計分析法 (8) 參、結果 (10) 　一、花粉圖譜與集群分析結果 (10) 　二、多變量分析結果 (14) 　三、距離與花粉量之關係──以琉球松為例 (16) 　四、表土花粉組成與植被組成之比較 (17) 肆、討論 (21) 　一、花粉圖譜、重要花粉類群與集群分析結果 (21) 　二、三種集群分析法之優劣 (28) 　三、地理環境因子對花粉組成的影響 (30) 　四、採樣尺度對資料的影響 (31) 伍、結論 (33) 參考文獻 (58) 附錄A、各表土樣本花粉類群比例資料 (65) 附錄B、選取17個表土花粉樣本與對應的18個植被調查樣區(陳等，2010)之類群對照 (73) 附錄C、表土花粉光學顯微照片 (92)11922778 bytesapplication/pdf論文公開時間：2014/08/25論文使用權限：同意無償授權表土花粉植被類型集群分析法降趨對應分析陽明山國家公園[SDGs]SDG15thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/261822/1/ntu-103-R99b44001-1.pdf
