基于基础地理数据统计的长三角城市主城区空间格局扩展研究

Research on Spatial Pattern of Main Urban Expansion in Yangtze River Delta Based on Statistics of Basic Geographic Data

在快速城镇化时期,城市主城区的空间格局变化最为显著,以其复杂性和扩展性为突出特征。研究其扩展变化对认识城镇化、优化城市空间结构等具有重要意义。本文在基础地理数据统计的基础上,对长三角城市主城区2002~2012年的空间扩展进行了分析,探索影响其演变的若干因素。

In a period of rapid urbanization, the main urban area changes most in the spatial pattern and the urban expansion process, being characteristic in expansibility and complexity. Studying on expansions of main urban areas is of great significance for understand- ing urbanization and optimization urban space structure. Based on statistics of basic geographic data, this paper analyzes the space ex- pansions of main urban areas in Yangtze River Delta since 2002 to 2012. And it approaches to explorer the factors which affects the e- volution of main urban areas in Yangtze River Delta.
