Geometrids are a species-rich group of moths that serve as reliable indicators for environmental changes. Little is known about the Mongolian moth fauna, and there is no comprehensive review of species richness, diversity, and distribution patterns of geometrid moths in the country. Our study aims to review the existing knowledge on geometrid moths in Mongolia. We compiled geometrid moth records from published scientific papers, our own research, and from the Global Biodiversity Information Facility (GBIF) to produce a checklist of geometrid moths of Mongolia. Additionally, we analyzed spatial patterns, species richness, and diversity of geometrid moths within 14 ecoregions of Mongolia and evaluated environmental variables for their distribution. In total, we compiled 1973-point records of 388 geometrid species. The most species-rich ecoregion in Mongolia was Daurian Forest Steppe with 142 species. Annual precipitation and maximum temperature of the warmest month were the most important environmental variables that correlated with NMDS axes in an analysis of geometrid assemblages of different ecoregions in Mongolia.

蒙古尺Geo蛾的多样性和分布模式

尺metri是一种物种丰富的飞蛾，可作为环境变化的可靠指标。对蒙古蛾类动物了解甚少，对该国蛾类物种的丰富性，多样性和分布模式也没有进行全面的综述。我们的研究旨在回顾蒙古关于几何蛾的现有知识。我们根据已发表的科学论文，我们自己的研究以及全球生物多样性信息基金（GBIF）编制了几何蛾的记录，以编制蒙古几何蛾的清单。此外，我们分析了蒙古14个生态区内的蛾类的空间格局，物种丰富度和多样性，并评估了环境变量的分布。我们总共编制了1973个点记录，记录了388个几何物种。蒙古物种最多的生态区是达里安森林草原，有142种。在分析蒙古不同生态区域的几何组合时，最暖月份的年降水量和最高温度是与NMDS轴相关的最重要的环境变量。
