中文摘要 | 竹類植物由於生長快速,所以具有很高的生物量累積和碳貯存能力,這類研究已在世界各地廣為 發表。刺竹是臺灣最為重要的優良竹種之一,具有多元的用途,本研究以此竹種為主要的研究材料。 研究所採用之樣竹取樣自臺灣南部地區,樣竹地上部各部位(葉、枝和稈)之生物量和碳貯存量已於之 前的研究分析完成(Lin et al. 2011)。本研究進一步以不同的allometric模式,包括general (I)、general (II)、WBE和Ruark模式,分析胸高直徑(diameter at breast height, DBH)和地上部各部位的關係,結果 顯示general (II)模式的推估效果最佳,採用此模式推估林分層級地上部生物量及碳貯存量分別為58.5 Mg ha-1和26.8 Mg ha-1 C,研究結果也顯示刺竹為具有高碳貯存潛力的竹種。 |
英文摘要 | Bamboo dominates in biomass accumulation and carbon storage due to its rapid growth, which has been widely reported worldwide. Thorny bamboo (Bambusa stenostachya) is one of the most dominant bamboo species in Taiwan due to its multiuse functions. The aims of this research were to access the aboveground biomass (AGB) and carbon storage capability of individual culms and at the stand level of thorny bamboo using 4 different allometric models: the general (I), general (II), WBE, and Ruark. The thorny bamboo of this study was sampled in southern Taiwan; its basic biomass accumulation and carbon storage of each aboveground component (leaves, branches, and culms) were determined in a previous study (Lin et al. 2011). We further analyzed the allometric relationships between the diameter at breast height (DBH) and each aboveground component based on various allometric models. The results showed that the general (II) model was the best predictor of AGB compared to the other models. We used this model to predict the AGB and carbon storage at the stand level obtaining amounts of around 58.5 Mg ha-1 and 26.8 Mg ha-1 C, respectively. The results illustrate that thorny bamboo possesses high potential for carbon storage. |
