广州城市空间形态特征与时空演化分析
Analysis on the Spatial-temporal Characteristics of Guangzhou City’s Spatial Morphologic Evolution
【摘要】 城市空间形态的形成和变化是城市内、外各种社会力量相互作用的物质空间反映。本文基于历史资料和遥感影像,探讨了近百年来广州城市空间形态特征和演变过程。广州城市空间形态演变依次经历了轮形团块期、触角期、分散组团式、轴向发展期、带形发展期、新的触角期等几个阶段。利用遥感方法对1979~2004年间广州市建成区变化的监测表明,该期间广州先后经历了20世纪80年代的相对稳定期、90年代前期的快速发展期、90年代中后期的平稳发展期和近年来的高速发展期,目前是扩展速度较快的时期。
【Abstract】 Based on the historic literatures and remotely sensed images, this paper studies the spatial-temporal characteristics of Guangzhou city’s spatial morphologic evolution in recent one hundred years, and summarizes the historic characteristics and the laws of urban development since the formation of Guangzhou, especially the period since the implementation of reform and open policies. On the whole, Guangzhou experienced two major stages, i.e., traditional urban development period before 1923 and modern urbanization development period from 1923 to 2004, covering several sub-periods of stabilization period and fast development period. The total increased built-up area of the city from 1979 to 2004 is 385.56 km2, an expansion of 3.46 times, and the average expansion rate is about 15.43 km2 per year. Many factors have contributed to the urban spatial morphologic evolution. But four major driving forces, i.e., economic development, institution and policy change, city planning and transportation system are the most important factors. Physiographic environment is the base of the city expansion;economic development is the inherent impetus for the evolution of the spatial morphology, and city planning plays a vital guiding role to the construction and development.
