2000―2010年广州人口空间分布变动与多中心城市空间结构演化测度

基于广州市第五次和第六次人口普查中的常住人口数据，运用空间分析法、单中心密度模型和多中心密度模型分析法对广州市人口空间分布和多中心城市空间结构进行研究。结果表明，研究时段内广州人口空间动态变化表现为“内圈层（近郊区）快速增长、外圈层慢速增长、核心圈层（核心区）和外圈低速增长”，核心圈层的人口继续增长并向四周扩散，表明广州人口变动的郊区化现象明显，已呈现多中心特征，由2000年的“1个中心（人民公园）2个次中心（白云区的新景街和海珠区的凤阳街）”演变至2010年的“1个中心（人民公园）4个次中心（白云区的同德街、海珠区的凤阳街、天河区的棠下街和沙河街）”，次中心的人口集聚功能逐渐增强，对城市人口分布影响逐渐增大。

Guangzhou Population Spatial Distribution and Polycentricity Spatial Structure Evolution

This paper uses the tabulations from 2000 and 2010 Population Censuses of Guangzhou to investigate the city’s demographic distribution and spatial structure. Spatial analysis, monocentric and polycentric population density models are implemented as analytical tools. The results are as follows: (1) The population spatial dynamic distribution of Guangzhou is that “population of the inner suburb grows fast, while that of the outer suburb slower, and that of the core circle the slowest”. (2) The population of Guangzhou’s inner city keeps growing and it also spreads to the suburban areas. Guangzhou’s polycentric structure has been consolidated by the increment of its subcentres. In 2000 there were two subcentres (Xinjing Street in Baiyun District and Fengyang Street in Haizhu District) and in 2010 there were six (Tongde Street in Baiyun District, Fengyang Street in Haizhu District, Tangxia Street and Shahe Street in Tianhe District). The subcentres are able to attract more people and also affect population distribution more significantly.
