本研究主要目的在了解不同年齡麻竹（Dendrocalamus latiflorus）主稈之生物量及碳蓄積效益，探討生立竹之生長特性並分析麻竹齡級之結構。樣區選定於南投縣魚池鄉，以每木調查方式進行。其結果顯示出麻竹齡以2至3年為多，隨竹高增加其含水率、材積、生物量及含碳量逐為下降；而材積、生物量及含碳量則隨竹齡增加逐年上升，含水率則因失水而逐年下降，材積與竹齡之關係式可得V= 12.403A^(0.2433)，生物量與竹齡之關係可得B= 5.857A^(0.4266)，竹齡與材積及生物量兼具顯著相關性，最後推估出麻竹林平均每公頃有9085株、材積每公頃137.5m3、生物量每公頃77.9噸及含碳量每公頃37.7噸。
The main purpose of this study is to investigate the estimates of biomass stock and carbon sequestration in Dendrocalannus latiflorus culms at different ages. Growth situatinn of standing bamboo and analysis of age group distribution were also included in this study. After selecting sample plots of Yue-Tzu Village, Nantou, each bamboo culm is examined and classified. The experimental results revealed that the number of Dendrocalamus latiflorus culms aged 2-3 is the most abundant. The moisture content, volume of bamboo, biomass stock and carbon sequestration of bamboo culms decreased with increasing height of bamboo culm., However, volume of bamboo, biomass stock and carbon storage increased with increasing age of bamboo. The moisture content decreased with increasing age. The relationship between bamboo volume(V) and age (A )can be drawn as V=12.403A^(0.2433), and B=5.857A^(0.4266) for the equation between bamboo biomass (B) and age (A). According to these two equations and investigation, the number of Dendrocalamus latiflorusis is estimated at 9085/ha, volume of bamboo in unit area is 137.5m^3/ha, biomass amount is estimated at 77.9 ton/ha, and the carbon sequestration is 37.7 ton per hectare.
