全球环境保护区年度数据（1990年,2000年,2010年,2012年）

该数据包括所有的国际保护区（海洋和陆地），包括联合国教科文组织世界遗产和其他国际公约，由联合国环境规划署（UnitedNationsEnvironmentProgramme,UNEP）建立完善的不同年份1:500万比例尺的全球环境保护区面积数据集，为自然地理、生物环境等相关学科领域的研究人员提供全球环境保护区的面积及分布状况。

This dataset encompasses all international protected areas (both marine and terrestrial), including UNESCO World Heritage Sites and those designated under other international conventions. It is a well-established, comprehensive global dataset that records the area and distribution of protected areas at a 1:5,000,000 scale across multiple years, developed by the United Nations Environment Programme (UNEP). This resource provides researchers in relevant disciplines such as physical geography and biological environment with data on the area and distribution of global protected areas.
