臺灣中部臺灣二葉松林火燒後植群演替之研究

Abstract

本研究針對中部地區惠蓀林場、東卯山及環山臺灣二葉松林火燒後不同演替階段進行調查，來探討火燒後植物恢復及植群組成情形。在分別設置5、8及10個樣區(樣區大小為10 m×25 m)，調查樣區內植物種類，結果環山樣區紀錄有25科38屬45種維管束植物；東卯山樣區紀錄有63科107屬142種維管束植物；惠蓀杜鵑嶺紀錄有44科67屬83種維管束植物，全部樣區總計共有76科147屬202種維管束植物(含種以下分類群)。東卯山依林分構造推估，目前在演替過程屬於「競爭」階段，依物種組成推估植物社會最終將演替成闊葉樹林；惠蓀杜鵑嶺依林分構造推估，目前在演替過程屬於「安定」階段，依物種組成推估植物社會最終將演替成闊葉樹林；而環山依林分構造推估，目前在演替過程屬於「競爭」階段，依物種組成推估植物社會最終將演替成臺灣二葉松-栓皮櫟林型。

This study focused on the investigation of various succession stages of Pinus taiwnensis forests at Hue-Sun Forest Station, Tungmao Mountain, and the Huanshan area. To understand the recovery and components of vegetation after forest fire. There are 5, 8, and 10 sampled plots at Hue-Sun Forest Station, Tungmao Mountain, and the Huanshan area, respectively (10m×25 m , each plot). Results showed that there are 25 families, 38 genus, 45 species of vascular plants at Huanshan area; 63 families, 107 genus, 142 species of vascular plants at Tungmao Mountain；44 families, 67genus, 83 species of vascular plants at Hue-Sun Forest Station. In total, there are 76 families, 147genus, 202 species of vascular plants in this study (including infraspecies taxa)。 According the stand structure and components of forest, it is indicated that the Pinus taiwnensis forests at Tungmao Mountain, the succession belongs to the “competition” stage, it will eventually success to hard wood forest. The vegetation of Hue-Sun Forest Station should be regarded to “stable” stage, it will eventually success to hard wood forest. The vegetation of Huanshan area should be regarded to “competiotion” stage, it will eventually success to Pinus taiwnensis –Quercus variabilis forest.
