Millennium Ecosystem Assessment: MA Rapid Land Cover Change

The Millennium Ecosystem Assessment: MA Rapid Land Cover Change provides data and information on global and regional land cover change in raster format for agriculture (cropland increase and disease), deforestation (forest mask and hotspots), desertification (hotspot areas of degraded land and degradation types), and fires (most frequent and exceptional fires). Urbanization data are in vector format for cities with the highest rate of change (1995-2015), largest cities (2000), and the overlay of these two data layers for the year 2000. This assessment identified the need to synthesize what is known about areas of rapid land cover change around the world in order to evaluate how the provision of ecosystem goods and services has changed.

千禧年生态系统评估：快速土地覆被变化快速评估（MA Rapid Land Cover Change）提供了全球及区域土地覆被变化的栅格格式数据，涵盖农业（农田扩张与疾病）、森林砍伐（森林掩膜与热点）、荒漠化（退化土地热点区域及退化类型）和火灾（最频繁及异常火灾）。城市化数据以矢量格式呈现，针对变化率最高的城市（1995-2015年）、最大城市（2000年）及其在2000年的叠加数据层。该评估确定了整合全球快速土地覆被变化区域已知信息的必要性，以评估生态系统商品与服务提供的变迁。
