【摘要】：基于1982年、1990年、2000年和2010年4次人口普查数据,利用洛伦兹曲线、基尼系数和人口密度等人口分布研究指标,分析了长三角都市区人口分布态势和地域格局;利用人口增减变化和人口商度等指标探讨了近30年来长三角都市区的人口增减变化和空间集疏情况。研究表明:(1)长三角都市区在保持较为均衡的人口分布态势下人口总量继续增加,上海市及主要大城市核心主导作用日益突出;(2)人口显著增加地区日益增多,人口减少地区逐步减少;(3)以人口强流入为主的人口空间集聚过程日趋激烈;(4)区域发展梯度和经济发展差异已成为人口空间集疏变化的主要诱因和拉力,城市化则是人口流动的主要推动力。
[Abstract]:Based on the data of four censuses in 1982, 1990, 2000 and 2010, and using the Lorentz curve, Gini coefficient and population density, the population distribution situation and regional pattern in urban area of Yangtze River Delta are analyzed. The changes of population and the spatial distribution of urban areas in the Yangtze River Delta in recent 30 years are discussed by using the index of population increase or decrease and population quotient. The study shows that the total population of the Yangtze River Delta metropolitan area continues to increase under the situation of maintaining a more balanced population distribution, and that the core leading role of Shanghai and its major cities is increasingly prominent. The regional development gradient and the difference of economic development have become the main inducement and pull force of the population spatial concentration, which is characterized by the strong inflow of population and the increasingly fierce process of population spatial agglomeration, and the regional development gradient and the difference of economic development have become the main inducement and pull force of the population spatial concentration. Urbanization is the main driving force of population mobility.
