摘要

臺灣是一個大陸性的島嶼，和周圍幾個小島位處於菲律賓－日本島弧的中心交界上。除了西部沙岸或泥岸之外，大約有三百種造礁珊瑚分布在臺灣及周圍的小島。以距離法及儉約法分析八個珊瑚礁生態調查資料庫中，包括軸孔珊瑚屬及菊珊瑚科一百零四種造礁珊瑚的分布形式。鄰聚分析皆顯示軸孔珊瑚和菊珊瑚在南臺灣和綠島的分布種類相似，而東北角則和澎湖相似。儉約分析軸孔珊瑚地理分群和由鄰聚分析所得結果一致，但是，儉約分析菊珊瑚則顯現東北角與臺灣和綠島形成一個群集。以儉約法分析合併軸孔珊瑚和菊珊瑚的分布資料，支持臺灣周圍的造礁珊瑚分布可分成兩大組群，而這兩大組群與海水表面溫度及海流流向呈現一致性。

Taiwan, a continental island with several offshore islets, is located on the center or junction of the Philippine-Japan island arc. Approximately 300 species of scleractinian corals occur around Taiwan and its neighboring islets except on the west coast with its sandy or muddy habitats. I analyzed the distribution patterns of 104 species of 2 major groups of scleractinian corals, the genus Acropora and family Faviidae, from 8 regional databases using distance and parsimony methods. Distance analyses (neighbor-joining) indicate that southern Taiwan and Green Island possess similar scleractinian distributions for both Acropora and Faviidae corals, whereas northeastern Taiwan groups with other locations of Penghu. Parsimony analysis (exhaustive search) of Acropora shows a similar pattern of distance analysis, whereas parsimonious tree of Faviidae united northeastern Taiwan with Green Island and South Taiwan leaving Penghu as a single group. Combining both Acropora and Faviidae, parsimony analysis suggests 2 distinct provinces of scleractinian distributions which show a congruence with sea surface temperatures and currents around Taiwan.
