摘　　要：以云南省城市为研究对象,根据《云南省统计年鉴》和《中国城市统计年鉴》等相关数据,采用主成分和GIS分析方法进行了城市中心性的地理空间分析。研究结果表明,城市中心性空间扩展体现了以昆明市为中心向外围延伸的多方向性,综合因子影响下的城市空间分布构成了云南省当前城市的基本空间格局;呈现"一核多极"的城市空间格局和"核心—环核心—外围"城市圈层结构;从城市群组角度看,呈现"核心—外围"的城市群空间格局,对进一步认识云南省城市中心性和优化空间布局具有较强的指导意义。This paper took the city of Yunnan Province as the research object, analyzed on geospatial of urban centrality, useing the 5tattSttcat Yearbook of Yunnan and the City Statistical Yearbook of China related to urban data and the principal component analysis method and GIS method .The results showed that the space expansion of urban centrality from Kunming to the periphery was the multi - directional, the urban spatial distribution constituted the basic spatial patterns of cities in Yunnan under the influence of integrated factor. The urban in Yunnan Province presented A core and multiple growth poles＂ urban spatial pattern. Yunnan＇ s urban presented ＂core - central coreperiphery＂ urban layer structure. The urban agglomeration in Yunnan Province presented＂core- periphery＇spatial pattern. Which had a strong guiding significance for a better understanding urban centrality and optimized spatial layout of Yunnan Province.
