中文摘要 | 政府自1995年起開始設置「空氣品質淨化區」藉由植栽綠化以達到改善空氣品質、增加碳吸存、提昇生活環境品質等多重環境效益,本研究調查五都共28個空氣品質淨化區之林木生長與碳儲存效益。調查結果顯示:栽植的林木種類約有99種,總調查株數為3963株,總平均樹高為6.31 m,總平均胸高直徑為17.77 cm,總平均冠幅為4.53 m,總平均胸高斷面積為0.040 m^2,總平均樹冠覆蓋面積為21.64 m^2,總平均林木單株材積為0.163 m^3,所有樣區之總林木材積為645.336 m^3,總平均林木單株碳儲存量為0.063 tons,所有樣區之總林木碳儲存量為251.036 tons。在五都所調查的99種喬木中,其中榕樹、小葉欖仁、台灣欒樹、樟樹在五都空氣品質淨化區栽植較為普遍。由於本研究僅有一次的調查資料,因此無法取得不同年度的生長資料,所分析的碳量結果僅為現有的碳儲存量,而非年變化量。因此在可量測、可報告與可查證前提下,需針對空氣品質淨化區之未來碳吸存效益進行持續性監測,可提供國家針對空氣品質淨化區之林木碳匯效益數量。 |
英文摘要 | In 1995, the national government in Taiwan began setting up air quality purification zones (AQPZs) by planting trees in order to improve the air quality, increase carbon sequestration, enhance the quality of the living environment, and achieve numerous other environmental benefits. This study investigated tree growth and carbon storage benefits in 28 AQPZs in Taiwan's 5 major municipalities (Taipei, New Taipei City, Taichung, Tainan, and Kaohsiung). Results of the survey showed that 3963 trees of 99 species had been planted in sample plots. Overall, the average tree height was 6.31 m, the average diameter at breast height was 17.77 cm, the average crown width was 4.53 m, the average basal area was 0.040 m^2, the average crown cover area was 21.64 m^2, the average individual tree volume was 0.163 m^3, the total timber volume of all sample plots was 645.336 m^3, the average individual tree carbon storage was 0.063 tons of C, and the total forest carbon storage capacity of all sample plots was 251.036 tons of C. Among the 99 tree species identified in the survey, Ficus microcarpa, Terminalia mantaly, Koelreuteria elegans, and Cinnamomum camphora were the most common in the AQPZs of the 5 municipalities. Since this study included survey date from only one time point, information on growth among different years could not be obtained, and the analysis of carbon content results applied only to currently existing carbon storage rather than to interannual variation. Therefore, under the premises of ”measureable, reportable, and verifiable,” continued monitoring of AQPZs is needed to provide quantification of future national carbon sink benefits. |
