摘要

華林（中國文化大學實驗林場）紅檜人工林於民國75年栽植，本研究目的為調查這些紅檜生長狀況及地被植群結構及分布情況，以供爾後撫育之參考依據。在6個10m×10m正方形樣區，紅檜計有135株，具分叉桿植株所佔比例達76%；枯立的桿數約佔全桿數10%；生立桿木平均高度為4.38m；總材積為2.70m^3。地被植群方面，在所設立24個5m×5m小樣區中，記錄到地被植物共92種，地被植群可細分為8個植物型，各地被植群型區間之種類相似度均低於0.6。

The main purpose of this study is to investigate. Vegetation structure on ground and growth distribution of Chamaecyparis formosensis plantation which was planted in 1986 in Hwa-Lin area(experimental forest of Department of Forestry Chinese Culture University) and current growth status was also examined for there ferences of silvicultural technique in the future, In six plots of 10m×10m,total of135 trunks were found. In all stands,76% with branching trunks and 10% dead standing trunks were estimated. Average height of live trunks was 4.38m and the total wood volume was 2.70m^3.In vegetation analysis of ground, experimental results revealed 92ground species were found in all 24 plots(5×5m^2)and the composition of groundvegetation was uniform with no exclusiveness. The analysis of ground vegetation could be classified into eight types and the similarity value between vegetation type was below 0.6.
