Indicative distribution map for Ecosystem Functional Group MT1.1 Rocky Shorelines

This archive contains indicative distribution maps and profiles for MT1.1 Rocky Shorelines, 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).

本存档包含MT1.1 岩质海岸线的示意性分布图与概况文档，该类群为世界自然保护联盟（International Union for Conservation of Nature, IUCN）全球生态系统分类体系（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）的相关研究。

本概况文档对核心生态特征与生态过程进行了简要总结；分布图仅用于示意全球分布格局，而非精细尺度的分布格局。本分布图展示了全球范围内该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）所在区域。其中，次要分布区指该生态系统功能群以斑块状散布于其他生态系统功能群构成的景观基质中，或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限制，本分布图仅可用于查询某区域内可能存在的生态系统功能群，而非特定点位的分布情况。本分布图的详细制作方法与参考文献均包含在该概况文档（xml格式）中。
