摘　　要：城市群是中国未来经济发展中最具活力和潜力的核心增长极,是我国城镇化的重要空间栽体,已成为国家区域政策的热点。按照都市区-联合都市区-准都市连绵区-都市连绵区的发育演化逻辑,以都市区为城市群的基本构成单元,以联合都市区、准都市连绵区、都市连绵区作为城市群的主要类型,利用全国2858个县级行政单元2010年的城区人口、城市化率、人均GDP、非农GDP比重、非农就业比重、经济密度和人口密度等指标,借助GIS软件对中国城市群发育格局进行整体识别。结果显示:2010年中国657个城市中共有325个都市区单元,包括大中心市239个,小中心市86个,外围达标县196个;发育形成由156个都市区、25个联合都市区、3个准都市连绵区(武汉、山东半岛和成德绵)和3个都市连绵区(长三角、珠三角、京津冀)构成的城市群总体空间格局。This paper follows the logic of urban agglomeration, that is, metropolitan area--joint metropolitan area--quasi metropolitan interlocking region-metropolitan interlocking region. Metropolitan area is the basic unit of urban agglomeration while joint metropolitan area, quasi metropolitan interlocking region and metropoli tan interlocking region are the main types of urban agglomeration. With the aid of GIS, this paper identifies the growth pattern of urban agglomeration based on data of urban population, urbanization rate, per capita GDP, the proportion ofnon-agricultural GDP, the proportion of non-agricultural employment, economic density and population density of 2858 county level administrative units in 2010. As the result shows, there were 325 metropolitan area units among 657 cities in china, including 239 big central cities, 86 small central cities and 196 peripheral counties. The overall pattern of urban agglomeration was formulated by 156 metropolitan areas, 25 joint metropolitan areas, 3 quasi metropolitan interlocking regions （Wuhan, Shandong Peninsula, Chengdu-Deyang-Mianyang region） and 3 metropolitan interlocking regions （Yangtze River Delta, Pearl River Delta and Bei- jing-Tianjin-Hebei region）. The paper also compares the six key urban agglomerations with the planning projections in terms of area, population and GDP. It is found that to use county-level administrative division as basic analytical unit and metropolitan area as basic component unit is effective for identifying and classifying the growth area of urban agglomeration in China because of data accuracy and comparability.
