本計畫為國內首次針對地層中的大型植物化石進行有系統的研究。金門在地理上較接近中國大陸地區，中國大陸已發現的晚第三紀植物群的產地多位於北方，有關南方的晚第三紀植物群研究相對較少，金門植物化石保存良好，地層保持完整，為研究東亞大陸先第四紀的古植被及古環境變遷的珍貴材料。化石出露點位於金寧鄉後湖附近環島公路旁，地質屬於先第四紀金門層。計畫內容分兩部分，擬就兩年時間分別執行。第一部分為標本採集、整理、分析、建檔與地層分析; 第二部分為化石植物分類鑑定，以及運用植物類群與氣候環境的關係探討金門地區古氣候環境。This study collected plant impression fossil from Houhu, Kinmen. To analysis the morphology, there are two types of samara seeds and 20 types of leaves in the fossil specimens. The taxa of the fossil leaves are including Pteridophyta, Aceraceae, Lauraceae, Fagaceae etc. The precise taxa are to be identified in the further study. The leaves fossil bed belongs to lateritic terrace deposits which is about 5000 years before present according to radiocarbon dating data. That is , this terrace deposits is possible Holocene terrestrial deposit came from ancient Choulong River.
