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. The status product consists of maps and summary statistics for each year and assessment level. 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的设计流程、定义与算法实现方案。本研究为欧洲森林行动（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。针对1990、2000、2006、2012、2018五个年份的空间森林覆盖情况，本研究采用2019年7月下载的哥白尼CORINE陆地覆盖数据集（Copernicus CORINE Land Cover，简称CLC，版本20）开展评估。研究将基于三个报告层级生成空间显式地图与统计汇总结果：全CLC覆盖范围、欧盟28国（EU28）以及国家层面。状态产品包含各年份与各评估层级对应的地图及汇总统计数据。变化产品重点展示了非林地与森林破碎化类别随时间发生变化的区域，该产品的时间跨度为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。
