This document describes the design process, definitions, and algorithmic implementation for the pan-European Assessment of Forest Fragmentation. This study is a preceding presentation of the indicator 4.7 in the State of Europe’s Forests 2020 report, published by FOREST EUROPE. The spatial forest coverage is assessed from the Copernicus CORINE Land Cover dataset (CLC, version 20, downloaded in July 2019) for the years 1990, 2000, 2006, 2012, 2018. Spatially explicit maps and statistical summaries are derived at three reporting levels: CLC (entire CLC coverage), EU28 and at country level.<br>The status product consists of maps and summary statistics for each year and assessment level.<br>The change product highlights areas where non-forest and forest fragmentation classes changed over time. The change product is provided for the time frame 2000 to 2018, which is the longest time span with comparable data coverage.

本文件阐述了泛欧洲森林破碎化评估（pan-European Assessment of Forest Fragmentation）的设计流程、定义与算法实现方案。本研究为欧洲森林进程（FOREST EUROPE）发布的《2020年欧洲森林状况》报告中指标4.7的前置研究成果。
空间森林覆盖度评估基于哥白尼CORINE土地覆盖数据集（Copernicus CORINE Land Cover dataset，简称CLC，20版本，2019年7月下载），涵盖1990、2000、2006、2012、2018五个年份的相关数据。研究生成了三类评估层级下的空间显性地图与统计摘要，分别为全CLC覆盖范围、欧盟28国（EU28）以及国家行政层面。
现状产品包含各年份及各评估层级下的地图与汇总统计数据。
变化产品重点展示了非森林与森林破碎化类别随时间发生变化的区域。该变化产品的时间跨度为2000年至2018年，这是当前具备可比数据覆盖度的最长时间区间。
