摘要 利用五普、六普和2015年全国1%抽样调查数据,计算了北上广深四座特大城市的区位熵、差异指数和多样性指数。研究发现,2000-2015年,我国特大城市流动人口形成近郊集中居住的环状区域,不同户口地类型流动人口分布特征和变化趋势不同。城市流动人口从近郊集中转向远郊扩散,镇流动人口从远郊集中转向郊区分散,农村流动人口从郊区集中转向城市各区域扩散。特大城市流动人口空间分异程度总体呈先加深后减少趋势,城市流动人口融合程度较好,镇的流动人口融合程度一般,农村流动人口融合程度较差;农村流动人口与本地人口的隔离程度最为严重。各特大城市人口多元化程度在15年间普遍上升且趋向一致,特大城市人口多样化指数可能存在0. 7左右的均衡点。 Based on 2000,2010 and 2015 Census data in Beijing,Shanghai,Guangzhou and Shenzhen,this essay measures residential segregation in megacities using the methods of Location Quotient,Dissimilarity Index and Diversity Variables.The results show that:From the year 2000 to 2015,the Location Quotient of the migrant population shows a clear ring structure in which migrants concentrated in suburb area;In detail,urban migranting population has moved from the inner suburbs to outer suburbs,migrants from town moved from outer suburbs to near suburbs,and rural migrants scattered from the outer suburbs to the whole cities;The residential segregation in the four megacities increased first and then fell,and the degrees of integration differ among different groups of migrants;Urban migrants have higher degree of integration and migrants from town is average,while rural migrants have faced more challenges in urban social integration;During the past 15 years,the Diversity Index of megacities had generally increased and tended to be the same,indicating that population diversities in the four megacities may reach an equilibrium point at about 0.7.
