摘要

探讨云南不同地理单元的物种、特有种、受威胁物种的组成及其系统发育多样性的变化,为云南生物多样性保护及资源可持续利用提供科学基础。在完善云南单子叶植物物种数据库的基础上,使用物种丰富度、加权特有性、受威胁程度、系统发育多样性、系统发育特有性、进化特异性全球濒危度指数等指标,揭示云南单子叶植物的空间分布格局,并整合自然保护地的分布,确定云南生物多样性保护的关键区域。结果表明:云南单子叶植物的物种丰富度与系统发育多样性、加权特有性与系统发育特有性、受威胁指数与进化特异性全球濒危度指数均显著(P<0.001)正相关;西北部、南部和东南部具有最高的物种组成和系统发育组成多样性和特有性;除西北部和东南部,其他区域的标准化系统发育多样性均较高;云南西北部、南部和东南部是单子叶植物的重点保护区域,采取有效措施加以保护,将有助于维持该地区生物多样性的进化历史和进化潜能。

Abstract

To explore the composition and phylogenetic diversity of species, endemics, and threatened species in different geographic units of Yunnan, and to provide scientific basis for biodiversity conservation and sustainable resource utilization in Yunnan. Based on the comprehensive Yunnan monocotyledon species database, the spatial distribution pattern of monocotyledon plants in Yunnan was revealed by using species richness, weighted endemic, threatened index, phylogenetic diversity, phylogenetic endemic, and evolutionary distinctiveness and globally endangered index, respectively, and the distribution of nature reserves was integrated, and the key areas for biodiversity conservation in Yunnan was identified. The results showed that species richness of Yunnan monocotyledons was significantly(P<0.001) and positively correlated with phylogenetic diversity, weighted endemism with phylogenetic endemism, threatened index with evolutionary distinctiveness and globally endangered; northwestern, southern, and southeastern Yunnan possessed the highest diversity and endemism in terms of species composition and phylogenetic composition; and the standardized phylogenetic diversity was higher in all regions except for northwestern and southeastern Yunnan; Northwestern, southern and southeastern Yunnan were the key conservation areas for monocotyledonous plants, and effective measures to protect them would help maintain the evolutionary history and evolutionary potential of biodiversity in the region.
