InVEST碳儲存模型與土地利用關聯之研究──以福智教育園區為例

The association of the InVEST carbon storage model and land use/cover changes-a case study of Bliss and Wisdom Educational Park

福智教育園區創建於2002年，提供眾人從幼年到老年的終身學習園地。福智教育園區位於台灣雲林縣古坑鄉，有國小、國中、高中、大學（籌備中），佔地40 ha，有住宅區、教育區與道路運輸、停車場等建設、植生綠地以及周圍120 ha的有機農田，園區內有1,437名師生、職員和志工。在福智教育園區的經營強調里山倡議精神，發揚永續發展的理念。校地範圍的前身是台灣糖業公司用地，以種植甘蔗生產蔗糖為用途。土地利用由原本貧瘠的甘蔗田成為具有環境教育意義之有機農田，蘊含豐富多樣的動植物生態。本研究探討福智教育園區歷年的地景變遷，並以InVEST模型計算2007至2018年的碳儲存量與碳儲存經濟價值，本研究結果指出：2007-2018年碳儲存能力（單位：kg/ha），整體趨勢隨時間上升，增幅最大為2009至2011年，為19.38%，整體增幅為84.85%，綠地與樹林提供了碳儲存重要的貢獻角色，在2018年時碳儲存量已達567.3 kg/ha。本研究建議未來土地規劃當以綠化土地為優先目標，期能有效達到減緩氣候變遷之目的。

The Bliss and Wisdom Educational Park (BWEP), established in 2002, provides a lifelong educational campus for general public. The 40-ha park, which surrounded by 120 hectares of organic farmland, is located in Gukeng Township, Yunlin County, Taiwan. The Park has educational institutions of elementary, middle, and high school, as well as a college that is under preparation. The Park also has a residential area and infostructures such as transportation and parking lots. The Park has a total of 1,437 students, teachers, staffs, and volunteers. The management of park emphasize the sustainable development concept of the Satoyama Initiative. The Park was previously a sugar cane farm that of the Taiwan Sugar Corporation. After the conversion from a barren sugar cane farmland to organic farmland, the biodiversity of the land was enriched substantially. This research studied the change of landscape of the Park from 2007 to 2018 and calculate the value of the carbon storage based on InVEST model. The results showed a general trend of increase in carbon storage, with 84.85% increase overall. The largest increase was from 2009 to 2011 of 19.38%. The carbon storage has achieved 567.3 kg/ha in 2018. The results suggested that forest and green land played an important role in carbon storage, and that green land should be prioritized for land planning to mitigate climate change in the future.
