Indicative distribution map for Ecosystem Functional Group TF1.5 Episodic arid floodplains

This archive contains indicative distribution maps and profiles for <strong>TF1.5 Episodic arid floodplains</strong>, a ecosystem functional group (EFG, level 3) of the IUCN Global Ecosystem Typology (v2.0). Please refer to Keith <em>et al.</em> (2020) for details. The descriptive profiles provide brief summaries of key ecological traits and processes, maps are indicative of global distribution patterns, and are not intended to represent fine-scale patterns. The maps show areas of the world containing major (value of 1, coloured red) or minor occurrences (value of 2, coloured yellow) of each ecosystem functional group. Minor occurrences are areas where an ecosystem functional group is scattered in patches within matrices of other ecosystem functional groups or where they occur in substantial areas, but only within a segment of a larger region. Given bounds of resolution and accuracy of source data, the maps should be used to query which EFG are likely to occur within areas, rather than which occur at particular point locations. Detailed methods and references for the maps are included in the profile (xml format).本归档包含TF1.5 间歇性干旱泛滥平原（TF1.5 Episodic arid floodplains）的示意性分布图与描述性概况文档，该类群属于国际自然保护联盟（International Union for Conservation of Nature, IUCN）全球生态系统分类法（v2.0）中的三级生态系统功能群（Ecosystem Functional Group，简称EFG）。详细信息请参阅Keith等人（2020）的研究成果。该描述性概况文档对核心生态特征与关键生态过程进行了简要概述；本分布图仅用于展示全球宏观分布格局，而非精细尺度的局部分布情况。分布图标注了全球范围内各生态系统功能群的主要分布区（数值为1，以红色标注）与次要分布区（数值为2，以黄色标注）。其中，次要分布区指生态系统功能群以斑块状零散分布于其他生态系统功能群的基质中，或是仅在大区域的局部片段内形成大面积分布的区域。鉴于源数据的分辨率与精度存在局限，本分布图仅应用于查询某区域内可能存在的生态系统功能群，而非用于确定特定点位的实际分布情况。本分布图的详细制作方法与参考文献已收录于该概况文档，文档格式为XML。
