摘要

本研究在台灣西南部荖濃溪下游西側設置20個500平方公尺的樣區，調查樣區內維管束植物的組成、結構及序列植被型。共記錄到97種木本植物（胸高直徑≥1公分），其中包含81個自生樹種及16個造林樹種；在地被層中，則記錄到68種木本植物及141種草本植物，其中包含47種藤本植物。使用群團分析法、降趨對應分析法及列表比較法將樣區分成5個序列植被類型，分別為（1）大青－紅楠型（2）九芎－山柚型（3）火筒樹－水錦樹型（4）台灣栲－克蘭樹型（5）構樹－蟲屎型。

The floristic composition, structure and sere vegetation types of secondary forests and plantations were investigated in downstream of the Lao-Nung creek, Southwestern Taiwan. Twenty 500 m² plots were established. Ninety seven woody species (DBH≥1cm, H≥1.3m) were recorded, including 81 native and 16 plantation species. In the ground layer, 68 woody species and 141 herbaceous species including 47 climber species were recorede. By using cluster analysis, detrended correspondence analysis and tabular comparison methods, the plots were classifiled into five regeneration types: (1) Clerodendrum cyrtophyllum-Machilus thunbergii type, (2) Lagerstroemia subcostata-Champereia manillana type, (3) Leea guineensis- Wendlandia uvariifoilia type, (4) Castanopsis for-mosana-Kleinhovia hospital type, (5) Broussonetia papyrifera-Melanolepis multiglandulosa type.
