摘要

鴛鴦湖為酸性湖泊，位於台灣北部之自然保留區內。此湖泊周圍山地生長了台灣重要的植物－紅檜和台灣扁柏，湖積物因此成為研究紅檜和台灣扁柏植株之消長的良好材料。本研究採集該區隸屬於三十科五十種植物的新鮮花粉，經處理後，以光學顯微鏡和掃瞄式電子顯微鏡觀察這些花粉的形態。依花粉萌芽口的不同，分為十一群：具氣囊、薄孔、三至六孔、多孔、螺旋孔、窗型、三溝、四至七溝、三溝孔、異溝孔、和四分粒具三溝孔的花粉。這些結果可做為研究鴛鴦湖湖積物內之花粉，並進而探討湖泊周圍植被變遷之先驅資料。

Yuenyang Lake is an acidic lake situated within a nature preserve in northern Taiwan. This lake is unique for the study of the succession of Chamaecyparis, one of the most important woods in Taiwan, which grows well in the area surrounding this lake. The pollen of fifty taxa belonging to thirty families collected from this nature preserve were investigated under light and scanning electron microscopes and described in the present study. A total of 11 pollen classes grouped on the basis of the aperture on the pollen wall were obtained: saccate, leptomatal, 3-6 porate, pantoporate, spiraperturate, fenestrate, 3-colpate, 4-7 colpate, 3-colporate, heterocolpate, and tetrad with monads 3-colporate pollen. The present data provide a basis for further study on changes in the environment of the terrestrial vegetation surrounding the Yuenyang Lake.
