摘　　要：对1990-2004年云南省城镇发展差异进行分析,发现自20世纪90年代以来云南省城市综合实力总体呈差异扩大的趋势,表现出小城市发展缓慢且分化不明显,少数高位城市极化,在空间呈现明显的核心—边缘倾向等特征。其后,进一步展示云南省城市经济影响区空间演化的阶段性规律:①20世纪90年代以前云南省城市经济影响区被特殊的地理环境分割成破碎且难以整合的小型离散化的格局;②自20世纪90年代以来,随着地区工业化和城市化加速进行,交通通讯网络的发育和辐射,中小城市得以发育,伴随于城市经济影响区空间扩张与收缩,云南省城市经济影响区逐渐从单层离散分布演变为三层嵌套结构,并不断朝更高级的结构形态演进,即云南省城市经济影响区空间呈现显著的、由小规模离散分布阶段、过渡转型阶段到嵌套复合阶段的时空演化序列。最后,针对这种时空演化序列,笔者解析出云南省城市经济影响区在不同时空条件组合下的三种空间扩展类型:单向拓展类型、多向拓展类型和邻接扩展类型。This paper analyzes the urban inequality of Yunnan Province during 1990 to 2004. The authors find that the differentiations among the comprehensive strength of cities of Ytmnan tend to increase since the 1990s. When most of the cities in Yurman sprawl slowly and change unobviously, only a few highest-rank cities are in the process of polarization, presenting clear central-peripheral effects. Thus, the urban economy organization that has influenced the evolution of the urban-regional structure has demonstrated these following features： （1） The urban economic effect region （UEER） in Yunnan was splitted into the discretization patterns that they were fragmentized in geography before the 1990s; （2） since the 1990s, with the fast pace of the regional industrialization and urbanization as well as the growth and the radiation of the communication network of transportation, the medium- and small-sized cities have been agitated. Furthermore, with the unbalanced spatial expansion and the shrinkage of UEER, that is, UEER has gradually transformed from a simple discrete distribution structure into a three-layered-nesting structure. The UEER of Yunnan begins to reveal the obvious spatio-temporal order： from the miniature discrete patterns and the transitional patterns to the three-layered-nesting structure patterns. Finally, based on this spatio-temporal evolutive sequence, the authors analyze the three types of the spatial spread of the UEER in different spatio-temporal combinations： dominant-direction spread type, the multi-direction spread twe and the abutting spread tvoe.
