East Yunnan-Kweichow Plateau is rich in biodiversity in China. Complex geographical and climatic conditions and rich bird resources made this area an ideal system for studying the spatial distribution mechanism and influencing factors of birds, which were still unknown. Bird community data from 37 sites in this region were collected, including 505 bird species and 164 species of resident passerine bird, were extracted for analysis. The taxonomic diversity, phylogenetic diversity, functional diversity (FD), and community structure index were calculated. Ordinary least square (OLS), spatial autoregressive models (SAR), and structural equation model (SEM) were used to explore the relationship between bird diversity index and environmental factors which were used to describe the habitat conditions of birds. Results indicated that species richness (SR), phylogenetic diversity (PD), and FD have similar distribution patterns and are mainly affected by vascular plant species richness, habitat area, and vertical altitude difference. The phylogenetic and functional structure of bird community changed in both longitude and latitude direction, and the phylogenetic structure of community was dispersed in the west and clustered in the east, significantly related to habitat area, and vertical altitude difference, the functional structure was dispersed in all sites, significantly related to average annual precipitation. The community in the west and south of the East Yunnan-Kweichow Plateau is mainly driven by interspecific competitive, while the process in the east and north is mainly driven by environmental filtration. Distribution pattern of bird diversity was caused by the comprehensive action of various habitat factors which were mainly related to food availability and habitat heterogeneity. For maintaining the living space of birds, the protection of urban parks, wetland parks, campuses, and other urban green spaces is as important as national and provincial nature reserves. Revealing the construction mechanism and main influencing factors of bird communities in different areas is conducive to targeted protection work.
滇东黔西高原是中国生物多样性丰富的地区。复杂的地理和气候条件以及丰富的鸟类资源，使该地区成为研究鸟类空间分布机制及其影响因素的理想系统，而这些机制和因素尚不清楚。收集了该地区37个地点的鸟类群落数据，其中包括505种鸟类和164种留鸟雀形目鸟类，并进行提取分析。计算了分类多样性、系统发育多样性、功能多样性（FD）和群落结构指数。采用普通最小二乘法（OLS）、空间自回归模型（SAR）和结构方程模型（SEM），探讨鸟类多样性指数与用于描述鸟类栖息地条件的环境因子之间的关系。结果表明，物种丰富度（SR）、系统发育多样性（PD）和FD具有相似的分布格局，主要受维管束植物物种丰富度、栖息地面积和垂直海拔差异的影响。鸟类群落的系统发育和功能结构在经度和纬度方向上均发生变化，群落的系统发育结构在西部呈离散分布，在东部呈聚集分布，与栖息地面积和垂直海拔差异显著相关；功能结构在所有地点均呈离散分布，与年平均降水量显著相关。滇东黔西高原西部和南部的群落主要受种间竞争驱动，而东部和北部的过程主要受环境过滤驱动。鸟类多样性的分布格局是由各种栖息地因素的综合作用造成的，这些因素主要与食物可利用性和栖息地异质性有关。为了维持鸟类的生存空间，保护城市公园、湿地公园、校园等城市绿地与国家和省级自然保护区同样重要。揭示不同地区鸟类群落的构建机制和主要影响因素，有利于开展针对性的保护工作。
