EVOLUTIONAL TRENDS OF POPULATION SPATIAL DISTRIBUTION STRUCTURE IN GUANGZHOU BASED ON EDSA- GIS TECHNIQUE
利用ESDA-GIS空间自相关技术，分析了广州市改革开放以来总人口、户籍人口和流动人口的空间分布结构及其演化趋势，发现多核心结构逐渐成熟，并探讨了居住地与户籍地分离现象及郊区化进程。
Based on technique of spatial auto-correlation in ESDA-GIS,spatial distribution structure and its evolutional trends of total population,local population and floating population in Guangzhou since reform are analyzed.It is approved that spatial concentrations of density of total population and local population with more and more obvious characteristics that statistic units with high values tends to concentrated and the same as low values.Multi-core spatial distribution structures of total population and local population are becoming more mature with several subcores distributing in outer boundary of central city.The separation of residential place and hukou place(ren hu fen li) is becoming obvious in central city.During the precess of population suburbanization with large scale of real estate developments as pioneers,large scale of construction of infrastructures of education and healthy etc.In suburban,especially the outer boundary of central city to decrease the extent of separation of residential place and hukou place and traffic demand between central city and suburban,should be strengthened.Multi-core spatial distributional structure of floating population has also been formed with the obvious spatial distribution pattern of relatively high density and homogenization of spatial concentration in central city and higher density of locally spatial concentration of outer boundary of central city.
