This document summarizes the design process, definitions, and algorithmic implementation conducted by the Joint Research Centre to support the development and implementation of FAO’s global forest analysis for the thematic topics Accounting and Fragmentation. The analysis scheme and data products were designed to support the indicator Forest Fragmentation in the State of the World's Forests (SOFO) report 2020.The spatial forest coverage is derived from the Copernicus Global Land Cover 2015 dataset (accessed in July 2019) and for 21 Global Ecological Zones (GEZ). The source data was re-projected to equal area to allow for comparable area estimates across the Globe. Spatially explicit maps and statistical summaries are derived at global level and for each of the 21 GEZ.<br>本文件总结了欧盟联合研究中心（Joint Research Centre）为支撑联合国粮食及农业组织（Food and Agriculture Organization, FAO）开展面向“核算”与“破碎化”两大主题的全球森林分析工作，所开展的设计流程、定义规范与算法实现。本次分析方案与数据产品，旨在为《世界森林状况（State of the World's Forests, SOFO）》2020年报告中的森林破碎化指标提供支撑。 空间森林覆盖数据源自哥白尼全球土地覆盖2015数据集（Copernicus Global Land Cover 2015，于2019年7月获取），覆盖21个全球生态区（Global Ecological Zones, GEZ）。源数据已被重投影至等面积坐标系，以实现全球范围内可比的面积估算。研究生成了全球尺度以及21个全球生态区各自的空间显性地图与统计汇总结果。
