摘　　要：海西城市群拥有得天独厚的地理位置,南北对接长三角和珠三角城市群,西临长江中游等内陆城市群,东与台湾隔海相望。其又在"一带一路"的海上丝绸之路中占有重要战略地位,因此,我国东部沿海的环渤海、长三角、海西、珠三洲及北部湾城市群将构成我国沿海城市带将有可能上升成为世界上最大的城市带。该文从人口规模上分析海西城市群2009—2017年的规模演变,了解海西城市群城市规模等级现状。并通过不同尺度的核密度分析研究和探讨海西城市群城镇聚集区域的空间分布格局,为海西城市群的发展提供参考。Haixi urban agglomeration has its unique geographical location,north-south to the Yangtze River Delta and Pearl River Delta urban agglomeration,West to the middle reaches of the Yangtze River and other inland urban agglomerations,east to Taiwan across the sea.It also occupies an important strategic position in the maritime Silk Road along the "one belt and one road".Therefore,the coastal Bohai Urban Agglomerations,Yangtze River Delta Urban Agglomerations,Haixi Urban Agglomerations,Zhuzhou Urban Agglomerations and North Gulf Urban Agglomerations will form the largest coastal city belt in the world.This paper analyses the scale evolution of Haixi urban agglomeration from 2009 to 2017 in terms of population scale,and understands the status of scale and grade of Haixi urban agglomeration.The spatial distribution pattern of urban agglomeration area of Haixi urban agglomeration is discussed through the analysis of nuclear density at different scales,which can provide reference for the development of Haixi urban agglomeration.
