臺北市林地植群生態之研究

Vegetation ecology of the forests in Taipei City

本研究於臺北市中心四周林地設置110個250 m2植群樣區進行植群調查，共調查維管束植物122科344屬523種（含栽培種），其中裸子植物4科5屬6種，雙子葉植物78科225屬337種，單子葉植物18科64屬88種，其中紅皮書名錄植物計14種。將樣區分成人工次生林與次生林後，經矩陣群團分析法（matrix cluster analysis, MCA）將植物社會組成分為20個林型，分別為1.人工次生林：A.相思樹─大明橘型（Acacia confusa─Myrsine seguinii type）、B.相思樹─鵝掌柴型（Acacia confusa─Schefflera octophylla type）、C.相思樹─九節木型（Acacia confusa─Psychotria rubra type）、D.相思樹─山紅柿型（Acacia confusa─Diospyros morrisiana type）、E.相思樹─香楠型（Acacia confusa─Machilus zuihoensis var. zuihoensis type）、F.相思樹─血桐型（Acacia confusa─Macaranga tanarius type）、G.森氏紅淡比型（Cleyera japonica var. morii type）、H.杜英─鵝掌柴型（Elaeocarpus sylvestris─Schefflera octophylla type）、I.杜英─山黃麻型（Elaeocarpus sylvestris─Trema orientalis type）與J.火廣竹型（Bambusa dolichomerithalla type）以及2.次生林：K.菲律賓榕型（Ficus ampelas type）、L.長梗紫麻型（Oreocnide pedunculata type）、M.鵝掌柴型（Schefflera octophylla type）、N.豬母乳型（Ficus fistulosa type）、O.九節木型（Psychotria rubra type）、P.香楠型（Machilus zuihoensis var. zuihoensis type）、Q.血桐型（Macaranga tanarius type）、R.紅楠型（Machilus thunbergii type）、S.山紅柿型（Diospyros morrisiana type）與T.大明橘型（Myrsine seguinii type）。

This survey investigated the vegetations of 110 plots of 250 m2 forests scattered in Taipei City. A total of 523 vascular plant species (including cultivars) in 344 genera and 122 families were recorded. 6 species were gymnosperms of 5 genera in 4 families. 337species were dicotyledons of 225 genera in 78 families. 88 species were monocotyledons of 64 genera in 18 families. 14 rare species in the Red List of Vascular Plants of Taiwan were recorded. These vegetations were classified into 20 types (10 types of secondary forest plantation and 10 types of secondary forest) by matrix cluster analysis (MCA). They were A. Acacia confusa─Myrsine seguinii type, B. Acacia confusa─Schefflera octophylla type, C. Acacia confusa─Psychotria rubra type, D. Acacia confusa─Diospyros morrisiana type, E. Acacia confusa─Machilus zuihoensis var. zuihoensis type, F. Acacia confusa─Macaranga tanarius type, G. Cleyera japonica var. morii type, H. Elaeocarpus sylvestris─Schefflera octophylla type, I. Elaeocarpus sylvestris─Trema orientalis type, J. Bambusa dolichomerithalla type, K. Ficus ampelas type, L. Oreocnide pedunculata type, M. Schefflera octophylla type, N. Ficus fistulosa type, O. Psychotria rubra type, P. Machilus zuihoensis var. zuihoensis type, Q. Macaranga tanarius type, R. Machilus thunbergii type, S. Diospyros morrisiana type, and T. Myrsine seguinii type.
