摘要

本文以19個樣區，225種植物及7個環境因子進行多變數分析，結果顯示棲蘭山170林道之植群變異主要受到地形位置、海拔高度、全天光空域及直射光空域等因子所影響，經降趨對應分析及列表比較法結果，可將本區植群區分為：1.高山芒－台灣扁柏型，為天然撫育下種之植群型；2.台灣杜鵑－台灣扁柏型，屬於上坡之植群型；3.台灣二葉松－台灣鐵杉型，為近稜線之植群型；4.木荷－台灣扁柏型，為中坡之植群型；5.紅檜－假長葉楠型，為溪谷之植群型。文中除說明植群分類及取樣分析方法外，並與附近之台灣扁柏林做比較。

The vegetation of Chamaecyparis forest was conducted by 19 stands with 225 plant species and 7 environmental factors sampled from Chilan shan 170 roads. It was found that the major significant factors affecting the vegetation distribution were the altitude, terrain position, whole light sky space and direct light sky space. From the analytical result using Detrended Correspondence Analysis (DCA) and tabular arrangement, the vegetation can be classified into 5 types. They were 1.Miscanthus transmorrisonensis - Chamaecyparis obtusa var. formosana type distributed at natural regeneration zone. 2.Rhododendron formosanum - Chamaecyparis obtusa var. formosana type distributed at upper slope which was near the former type. 3.Pinus taiwanensis - Tsuga chinensis var. formosana type distributed at ridge slope. 4.Schtma superba var. superb - Chamaecyparts obtusa var. formosana type distributed at middle slope. 5.Chamaecyparis formosensis - Machilus japonica type distributed at valley bottom .Discussions were made with the past research of Chamaecyparis forest in the nearby area.
