摘　　要：以扬子江城市群为研究对象,从城市群建成区扩张和城镇空间联系两个角度进行指标分析,综合测度了2005年、2010年、2015年的城市群城镇发展水平,并利用探索空间数据分析法对城市群城镇空间格局进行了研究。结果表明:①监测周期内,城市群各市的扩张均处于全省前列,“十一五”和“十二五”期间扬子江城市群建成区扩张迅速、效应明显,3期城市群建成区空间重心都集中在扬子江以南的常州市境内,表明扬子江以南的城镇发展规模优于江北;②从城镇空间联系来看,宁镇杨、苏锡常、苏通等城市组群的联系相对明显,构成了整个扬子江城市群的基本联络骨架,城市群内部各城市与周边城市之间、小城市与大城市之间的联系紧密,构成了联系网络。In this paper, taking Yangtze River urban agglomeration as the study area, we carried out the index analysis from urban agglomeration expansion and urban spatial connection, comprehensively measured the city development levels of urban agglomeration in 2005, 2010 and 2015, and used the exploratory spatial data analysis method to study the spatial pattern of urban agglomeration. The results show that(1) during the monitoring period, the expansion of cities in urban agglomeration are at the forefront of whole province. The built-up areas of the Yangtze River urban agglomeration expand rapidly with obvious effect during the 11 th and 12 th Five-year Plan period. The spatial gravity centers of the urban agglomeration concentrate in the territory of Changzhou, which shows that the scale of urban development in south of Yangtze River are better than that of the north.(2) In the point view of the urban spatial connection, the correlations of Nanjing-Zhenjiang-Yangzhou, Suzhou-WuxiChangzhou, Suzhou-Nantong and other urban agglomerations are relatively obvious, which constitute the basic liaison skeleton of the Yangtze River urban agglomeration. The relationship between the cities within the Yangtze River urban agglomeration and the surrounding cities, and the relationship between the small cities and the major cities, constitute the Yangtze River urban agglomeration contact network.
