台湾土地利用变迁及其永续发展之研究

Sustainable Development and Land Use Changes in Taiwan

台湾的土地利用与地表覆盖变迁 (L and Use/ Cover Changes,L U CC)一直为地理学与相关学科研究者所关心。其中 ,大部分的研究侧重于土地利用与地表覆盖变迁的环境分析 ,另一些则专注于特殊土地利用与地表覆盖型态的空间分布的调查与研究。十年前 ,台湾的学者与政府机构开始参与国际性 L U CC研究。目前已参与的研究活动例如 ::the Southeast Asian Regional Comm ittee(SARCS) for Global Change System for Analysis,Research andTraining(START) ,L U CC- IGBP(the International Geosphere- Biosphere Programm e) ,L UCC- IHDP(the Hum anDim ensions of Global Environmental Change Program me) ,IGU - L U CC(International Geographical U nion)以及其它国际性 L U CC相关研究议题。建立不同时期土地利用与地表覆盖的时序数值数据库 (tem poral database) ,是从事L U CC研究重要的一项工作 ,本文重点论及台湾的土地利用与地表覆盖的数值数据库 ,及其以往 40年来土地利用的变迁。

Land use/cover changes(LUCC)have long been important issues in Taiwan. Many studies have been done by geographers and related researchers. Most work investigated environmental impacts of land use/cover changes. Some focused on the issue of exploration or explanation of spatial distribution of specific land use/cover pattern. Since last decade, university experts and government agencies in Taiwan have conducted many international LUCC studies. They have actively involved in research activities in the Southeast Asian Regional Committee(SARCS)for START(Global Change System for Analysis, Research and Training), LUCC IGBP(the International Geosphere Biosphere Programme), LUCC IHDP(the Human Dimensions of Global Environmental Change Programme), IGU LUCC(International Geographical Union)and other international LUCC related research activities. To establish temporal digital databases of land use/cover in different periods is the most important work for the study of LUCC. This research is an attempt to present briefly LUCC studies for several sources in Taiwan. The digital databases of land use/cover in Taiwan are introduced. In additions, a browsing of LUCC over past 40 years is also described.
