摘　　要：近年来,中国城市发展中的等级规模结构面临着剧烈重组,突出表现为以中心城市为组织核心的都市圈和城市群日益成为城镇化的主体形态,即城镇体系变动呈现出大城市偏向的空间集聚态势。县域作为新型城镇化空间格局的基础构成,面广量大,在新发展格局中缺乏充分的研究关注。选取1853个县域作为研究对象,结合现有规划和研究中19个城市群、36个都市圈的范围划定,以及圈群中心城市对不同位置县域的影响,确定大都市辐射县域、圈群潜力地区县域、圈群空隙地区县域等3种类型,即透过圈群组织视角分析中国县域城镇化格局。利用县域七普数据和相关公开数据,基于熵值法确定的权重,从人口、经济、社会、土地等4个维度对中国县域综合城镇化水平进行测度,提炼总结现阶段县域城镇化的空间格局特征,并为后续的县域规划实践提出相应政策参考。In recent years,China's urban hierarchy has undergone drastic restructuring,with metropolitan regions and city agglomerations centered on central cities becoming the primary spatial form of urbanization,favoring key cities in the urban system.However,counties.which cover China's vast territory and are crucial for supporting new urbanization,have received scant scholarly attention.This research addresses this gap by examining 1,853 selected counties.Drawing insights from the defined scope of 19 city agglomerations and 36 metropolitan regions,and taking into account the influence of key cities in various locations,the paper classifies selected counties into three types:those in the metropolitan radiation area,those under the potential influence of metropolitan regions and city agglomerations,and those in the gap areas.The study analyzes China's county-level urbanization pattern through the lens of metropolitan regions and city agglomerations.Utilizing data from the seventh national census and other relevant public statistical sources for county level jurisdictions,as well as weights determined by the entropy method,the paper measures county-level urbanization levels using indicators of population,economy,society,and land.Furthermore,the paper summarizes the spatial pattern characteristics of current county-level urbanization and proposes corresponding planning policies for each of the three types of counties.
