隘寮溪流域植群分類與製圖

Vegetation Classification and Mapping of Ailao River Basin

隘寮溪流域位於台灣南部高屏溪河系。本研究在海拔969-3038m設置133個樣區調查植物組成並分類隘寮溪流域植群，以繪製現生植群圖。本區計有維管束植物124科309屬620種；其中包含有稀有植物有16種。矩陣群團分析進行植群型之分類，可將本區之森林植群區分為山地針闊葉混淆林、山地常綠闊葉林以及下部山地常綠闊葉林等3個群系；台灣鐵杉群團、赤柯群團、台灣八角群團、石斑木群團、銳脈木薑子群團、屏東木薑子群團等6個群團；厚葉柃木－台灣鐵杉群叢、昆欄樹－赤柯群叢、白花八角－台灣鐵杉群叢、尾葉灰木－紅檜群叢、高氏木犀－長尾柯群叢、石斑木－台灣杜鵑群叢、銳脈木薑子－長尾柯群叢、瓊楠－台灣赤楊群叢、燈稱花－墨點櫻桃群叢等9個群叢。植群圖以群系階層為製圖單位，並利用分類結果共分出上部山地針葉林、山地針闊葉混淆林、山地常綠闊葉林、下部山地常綠闊葉林、人工林以及其他（建地裸露地水域墾地竹林）等六項製圖單位。 The purpose of this study is the vegetation mapping of Ailiao River Basin northern Pingtung County. A total of 133 plots from altitude 969m to 3038m were investigated. There were 620 vascular plant species recorded in the floristic that contained 16 rare species. By using matrix cluster analysis of plot data, the forest vegetation could be divided into montane mixed coniferous broad-leaved forest formation, montane mixed coniferous broad-leaved forest formation, submontane evergreen broad-leaved forest formation; Tsuga chinensis alliance, Illicium arborescens alliance, Rhaphiolepis indica alliance, Litsea acutivena alliance, Litsea akoensis alliance; Eurya glaberrima- Tsuga chinensis association, Trochodendron aralioides- Cyclobalanopsis morii association, Illicium anisatum- Tsuga chinensis association, Symplocos caudate- Chamaecyparis formosensis association, Osmanthus kaoi- Castanopsis cuspidata var. carlesii association, Rhaphiolepis indica- Rhododendron formosanum association, Litsea acutivena- Castanopsis cuspidata var. carlesii association, Beilschmiedia erythrophloia- Alnus formosana association, Ilex asprella- Prunus phaeosticta association. Vegetation Mapping showed six formation units, including upper montane coniferous forest, montane mixed coniferous broad-leaved forest, montane mixed coniferous broadleaved forest, submontane evergreen broad-leaved forest, artifical forest, and others.
