Due to plantations with high productivity, numerous researches have reported growing stock, biomass accumulation and carbon storage of various species in Taiwan. We collected these published data of plantations as the basis for further analyze. Since the purpose of the present study was to assess the ability of carbon sequestration (CE) of plantations, all of different data were transferred into CE for plantations. Three major plantation types were categorized, namely coniferous, broadleaf and bamboo plantations. The data set also contained other stand characteristics, such as mean diameter at breast height, mean tree height, stand density, average annual temperature, annual rainfall and altitude above sea level. We analyzed the relationships between the CE and other stand characteristics based on the correlation analysis; however, the stand characteristics which had significant correlation with the CE were not consistent among the plantations of different types. Moreover, we compared the CE among which plantations using an analysis of variance and the least significant difference method, and found that bamboo plantations had higher CE value (5.47±3.84 Mg ha-1 yr-1) than that of coniferous plantations (2.69±1.04 Mg ha-1 yr-1) and broadleaf plantations (2.20±1.07 Mg ha-1 yr-1).
由於人工林具有高生產力的特性，過去已有許多研究探討臺灣不同種類人工林的蓄積量、 生物量及碳貯存量，本研究蒐集這些資料為基礎進行分析，由於本研究的目的在於探討人工林之 碳吸存能力，因此須先將所蒐集之上列資料轉換為碳吸存量。本研究將資料區分為人工針葉樹林、 闊葉樹林及竹林等三大類型，基本資料包括林分的其他性態值，如平均胸徑、平均樹高、林分密度 、年均溫、年雨量及海拔高等。由相關分析探討三種類型人工林之碳吸存量和其他林分性態值之相 關性所得結果發現，和碳吸存量具顯著相關的林分性態值在三種不同類型人工林的表現並不具一致 性。此外，以變方分析和最小顯著性差異法比較三種類型人工林之碳吸存量，所得結果呈現竹林 (5.47±3.84 Mg ha-1 yr-1) 明顯高於針葉林 (2.69±1.04 Mg ha-1 yr-1) 和闊葉林 (2.20±1.07 Mg ha-1 yr-1)。
