以2020–2021國土利用現況調查成果資料繪製臺灣濕地分布圖

Mapping of Taiwan's wetland distribution using the 2020–2021 land use investigation data

臺灣為推動濕地生態之保育，濕地保育法業於2015年2月2日開始施行，惟有關臺灣濕地之類型、面積及分布等基礎資訊仍不完整。本研究以內政部2020–2021年更新維護之國土利用現況調查成果資料為材料，配合相關遙測影像資料與介接影像平台，將國土利用調查資料93類與拉姆薩公約之濕地分類類型42類按其定義進行配對，並以地理資訊系統軟體萃取濕地類型，完成製圖與分析，以瞭解臺灣濕地之空間分布。研究篩選出拉姆薩濕地類型計有24類，包括海洋／海岸濕地9類、內陸濕地5類及人為濕地9類，面積合計46.2萬ha，此資訊可提供濕地相關研究基礎資料，以及濕地管理單位在決策、規劃及經營管理之參考與應用。

In order to promote the conservation of wetlands in Taiwan, the Wetland Conservation Act came into effect on February 2, 2015. However, basic information, such as the types, areas, and distribution of wetlands in Taiwan, were still incomplete. In this study, the data from the Land Use Investigation maintained by the National Land Surveying and Mapping Center, Ministry of the Interior for the years 2020 to 2021 were used, along with relevant remote sensing imagery and integrated image platforms. The Land Use Investigation data, consisting of 93 categories, were matched with the 42 wetland classification types defined by the Ramsar Convention, and those wetland types were extracted by using Geographic Information System (GIS) software for mapping and analysis to understand the spatial distribution of wetlands in Taiwan. The study identified 24 Ramsar wetland categories, including 9 marine/coastal wetland categories, 5 inland wetland categories, and 9 artificial wetland categories, with a total area of 462,000 hectares. This information could serve as a foundational dataset for wetland-related research and provide wetland management authorities with references and applications in decision-making, planning, and operational management.
