中文摘要：

基于第四、五、六次全国人口普查数据,运用人口密度模型等工具对1990―2010年广佛都市区的人口空间分布进行了研究。结果发现：广佛都市区人口空间分布可以用单中心人口密度模型进行解释;同城化地区与总体规律相比,同城化进程对边界地区有显著的提升作用,但这种提升具有主体的差异性。广州市没有主动向佛山发展的动力,而次一级的行政区域主体（佛山市）对融入广州市中心的发展则呈现较高的意愿。

英文摘要：

This research models the population densities in Guangzhou and Foshan metropolitan area with data from the fourth, fifth and sixth national population censuses. 1） Monocentric population density functions can well describe population density distribution of Guangzhou and Foshan metropolitan area. 2） By applying the population functions, this research describes the population density change in city integration areas. As Guangzhou and Foshan metropolitan area becomes more regionally integrated, the population density in city integration areas is increased. Furthermore, city integration areas within Foshan City are more willing to be integrated into the core area.
