中文摘要 | 生物呼出二氧化碳,而植物吸收進行光合作用生長,此過程在自然界中會達到平衡。近代隨著不斷消耗天然資源及改變原有土地利用方式,造成而二氧化碳排放量增加,進而造成全球暖化現象嚴重;因此如何減少向大氣排放二氧化碳已成為世界各國共同關注的一個重大政治經濟問題。台灣紅土台地因鄰近都會區,為都會區增加碳存量之重點區位。本研究以大肚台地保安林為研究樣區,利用1995及2008年兩期土地利用圖資,應用景觀生態指數分析及參照「綠建築解說與評估手冊」估算碳存量,以了解碳存量與植群變遷的關係。結果顯示北區保安林受火燒影響,林地面積逐漸退縮;南區保安林則因有造林計畫,受火燒事件影響較小,因此林地碳存量相對較高。造林計畫雖能藉人力操作,避免草地擴張降低林地碳存量;但火燒強度干擾之保安林地,其造林計畫之後續管理策略仍宜以最少干擾為原則,方能達到造林效果並維持原有生態之目標。 |
英文摘要 | Terrestrial plants play an important role in the global carbon cycle by absorbing carbon dioxide (CO2) during photosynthesis. Recently, the overconsumption of natural resources and rapid land use changes resulting in CO2 emission and global warming situation become more serious. Thus, the CO2 emission reduction has become a global political and economic issue. The protection forests in Dadu terrace, which surrounded by urbanized area, were selected to be a case study. Landscape indices were calculated based on 1995 and 2008 land use maps and carbon storage was estimated according to “Green Building Interpretation and Assessment Manual”. The results showed that the forest area of northern protection forest decreased due to wildfire comparing to southern protection forest. The carbon storage in southern protection forest is higher than that of northern protection forest. The reforestation project could maintain the balance of ecosystem, effectively protect the forestland from invasion of grasses and significantly increase carbon storage. However, concepts of minimizing disturbance should be emphasized to achieve the ecological restoration and natural succession. |
