Indicative distribution map for Ecosystem Functional Group T5.3 Sclerophyll hot deserts and semi-deserts

This archive contains indicative distribution maps and profiles for T5.3 Sclerophyll hot deserts and semi-deserts, a ecosystem functional group (EFG, level 3) of the IUCN Global Ecosystem Typology (v2.0). Please refer to Keith et al. (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).

本数据集归档文件包含T5.3硬叶热荒漠与半荒漠的示意性分布图与描述性概览，该类群为国际自然保护联盟（IUCN）全球生态系统分类体系（v2.0）中的三级生态系统功能群（EFG）。详细信息请参阅Keith等人（2020）的研究成果。

本描述性概览简要总结了核心生态特征与生态过程；分布图仅用于展示全球分布格局，并非用于呈现精细尺度的分布特征。该类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（值为1，以红色标注）与次要分布区（值为2，以黄色标注）。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，或仅在大区域的局部范围内形成连片分布的区域。鉴于源数据的分辨率与精度限制，本分布图仅应用于查询某一区域内可能存在的生态系统功能群，而非特定点位的物种分布情况。分布图的详细编制方法与参考文献均收录于该概览文件（xml格式）中。
