Studies on altitudinal zonation of forest vegetation in central Taiwan

本研究計畫為一為期三年之課題，旨 在了解台灣中部森林的垂直分布帶之特 性。本年度為計畫之第一年，調查對象選 定台灣玉山地區針葉樹天然林為主，針對 其種組成、群落構造和種多樣性進行解 析。期望透過3 年的野外調查資料之分析， 掌握森林之優勢種在海拔高度變化時的消 長傾向。藉此等結果，與同屬東亞季風氣 候區的其他高山的森林垂直分布帶作比 較，以凸顯台灣森林的垂直分布特徵，同 時探討它在更廣域地區的定位問題。This is a project of 3 years to study the altitudinal zonation of forest vegetation in central Taiwan.In these mountains the altitudinal changes of species composition ， forest structure and species diversity will be investigated.The purpose of this investigation is to confirm existence of the forest zone by the distribution groups in the vertical distribution range of ligneous plants. The altitudinal zones of central Taiwan mountain will compare with those in other mountains of east Asia ，the remarkable uniqueness of it and its importance is discussed
