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.本文件总结了联合研究中心（Joint Research Centre）为支撑联合国粮食及农业组织（Food and Agriculture Organization of the United Nations, FAO）开展“核算与碎片化”主题领域的全球森林分析所完成的设计流程、定义规范与算法实现。本次分析的框架与数据产品，旨在支撑《世界森林状况（State of the World's Forests, SOFO）2020年报告》中的“森林碎片化”指标。空间森林覆盖数据源自2015年哥白尼全球土地覆盖（Copernicus Global Land Cover 2015）数据集（2019年7月获取），覆盖全球21个全球生态区（Global Ecological Zones, GEZ）。原始数据已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及21个全球生态区各自的空间显性地图与统计汇总结果。
