摘　　要：以地理国情监测的城镇建成区数据为基础,设计了基于多个时期城镇建成区的多层次城镇发展空间变化趋势分析方法,并以江苏省为例,从省域、城市群和城市3个层级开展了城镇发展趋势研究,对城镇空间重心演变进行统计和分析,总结不同层级城镇发展的变化趋势和相互关系,从空间上探索城镇发展总体规律,为城镇发展趋势相关研究提供一定的科学借鉴。From the perspective of spatio-temporal analysis,based on the urban built-up areas data of geographical conditions monitoring,we designed a multilevel analysis method of urban development trend based on the multi-period urban built-up areas.Taking Jiangsu Province for example,we studied the urban development trend from three levels,including the province level,the urban agglomeration level and the city level,made statistics and analysis on the evolution of urban gravity center,and summarized the change trend and mutual relationships of urban development at different levels.And then,we explored the general rule of urban development from space,which could provide some scientific references for the related research of urban development trend.
