中文摘要：

运用分形理论中的边界维数对重庆市近30年的城市空间结构形态变化进行定量分析,揭示重庆市不同时期的城市地域扩展方式.结果显示,重庆市主城区各区在各个时期城市形态具有差异,整体上重庆市城市建成区在30年间的发展使得图形破碎度降低,其中1980～1997年为城市地域的快速发展期1,997～2001年为高速波动发展期,2001～2010年为高速发展并有趋于稳定趋势发展期.

英文摘要：

It reveals the means of urban geographic expansion of Chongqing in different periods when using boundary - dimensional in fractal theory to conduct quantitative analysis about pattern changes of Chongqing urban spatial structure for recent 30 years and it turns out that there are discrepancies among Chongqing city districts in various periods and the development of Chongqing urban built - up areas over the 30 years has lowered graphic fragmentation degree as a whole. 1980 to 1997 was the time for rapid development of urban regions while 1997 to 2001 for high - speed fluctuation development and 2001 to 2010 high - speed for development which tends to stabilize.
