中文摘要：

以山东半岛城市群为例,集合最小需求法、Moore回归分析法、Nelson城市职能统计分析法、灰色系统理论等方法,分析了高速公路对城市群内不同城市职能结构演化的影响.结果发现,高速公路发展对沿线城市职能结构变化有重要影响,能够促使部门职能强度在各种流的强化和转换过程中发生强弱变化,加快城市主要职能的演化,城市性质也随之而不断变化.

英文摘要：

Shandong peninsula urban agglomeration is taken as an example,the influence of the expressway on the evolution of functional structure in different cities of the urban agglomeration is analyzed,the minimum requirements method,Moore regression analysis,Nelson urban function statistical analysis and the gray system theory are used.The results show that the construction of expressways plays a significant role in the functional structure adjustment of the cities;expressways can strengthen or weaken function intensity in a variety of flows and conversion processes,promoting the evolution and transformation of city＇s main functions which will change designated function of city constantly.
