Visual data on the geographic distribution of carbon storage help policy makers to formulate countermeasures for global warming. However, Taiwan, as an island showing diversity in climate and topography, had lacked valid visual data on the distribution of forest carbon storage between the last two forest surveys (1993-2015). This study established a model to estimate and illustrate the distribution of forest carbon storage. This model uses land use, stand morphology, and carbon conversion coefficient databases accordingly for 51 types of major forests in Taiwan. An estimation in 2006 was conducted and shows an overall carbon storage of 165.65 Mt C, with forest carbon storage per unit area of 71.56 t C ha, where natural forests and plantations respectively contributed 114.15 Mt C (68.9%) and 51.50 Mt C (31.1%). By assuming no change in land use type, the carbon sequestration from 2006 to 2007 by the 51 forest types was estimated to be 5.21 Mt C yr using historical tree growth and mortality rates. The result reflects the reality of the land use status and the events of coverage shifting with time by combining the two forest surveys in Taiwan.
碳储存地理分布的可视化数据有助于政策制定者制定应对全球变暖的对策。然而，台湾作为一个气候和地形多样的岛屿，在上两次森林调查（1993 - 2015年）期间，缺乏关于森林碳储存分布的有效可视化数据。本研究建立了一个模型来估计和说明森林碳储存的分布。该模型相应地使用了台湾51种主要森林类型的土地利用、林分形态和碳转换系数数据库。2006年的估计结果显示，总碳储存量为165.65 Mt C，单位面积森林碳储存量为71.56 t C/ha，其中天然林和人工林分别贡献了114.15 Mt C（68.9%）和51.50 Mt C（31.1%）。通过假设土地利用类型不变，利用历史树木生长和死亡率估计，2006年至2007年这51种森林类型的碳固存量为5.21 Mt C/yr。通过结合台湾的两次森林调查，该结果反映了土地利用现状以及随时间的覆盖变化情况。
