摘要

本研究係調查台灣北部地區豔紅鹿子百合(Lilium speciosum Thunb. var. gloriosoides Baker)之物候學、生育地及植物社會，並進行種子發芽試驗，以觀察其種子發芽率。調查地區位於台灣北部台北縣及基隆市間，海拔高度約為150-600m處，除調查環境因子外，並記錄各樣區之植物種類及計算出覆蓋度。在該等地區設立17個樣區並共記錄有78種植物，利用雙向列表比較法、矩陣群團分析及降趨對應分析後，可分成兩個植群型，一為台灣蘆竹－火炭母草型，另一為五節芒－長梗紫麻型。根據調查分析結果顯示，豔紅鹿子百合生長的植物社會中以台灣蘆竹與五節芒為最優勢，生育地微環境因子中，以方位、全天光空域為正相關，野外繁殖方法以種子、鱗莖、株芽為主，由於艷紅鹿子百合具藥用、食用、觀賞之價值，長期過度採集的結果數量已極度減少，期盼在基本資料建立後，能提供保育決策之參考。

The objective of this research is to study the phenology, habitat and communities of Lilium speciosum Thunb. var. gloriosoides Baker in northern Taiwan. Seed germination test was also conducted for determination of its germination ratio.
The investigated areas were located in Taipei county and Keelung city, with altitude ranging from 150 to 600m above sea level. A total of 17 plots were surveyed. Environmental factors, such as topography, altitude, slope, rock moisture, stoniness, aspect, WLS, pH value and available phosphorous were also investigated; coverage of the plants at plots were also calculated. A total of 78 vascular plants were recorded.
By TWINSPAN, DCA and MCA analysis methods, two types of plant communities were recognized; there were:
1. Arundo formosana-Polygonum chinese type
2. Miscanthus floridulus-Villebrunca pedunculata type.
According to the result, the latter is the dominant one.
As to the micro-environmental factors of the habitat, the position and WLS were most important. Since the Lilium speciosum Thunb. var. gloriosoides Baker could be used for medicine, food and landscaping purposes, their amounts drastically reduced by chronically over-harvesting. Therefore, the Council of Agriculture, Executive Yuan listed this plant as a endangered species, the results of this research was expected to served as the reference for future conservation measures.
