【摘要】：从三个尺度上即圈层尺度、地级市尺度以及区县尺度利用第五和六次人口普查数据分析了近10年长三角人口空间分布特征变动。10年间,长三角人口规模进一步扩大,人口密度进一步稠密,反映了作为我国经济发展增长极的不断增强的人口集聚能力。从圈层变动来看,人口向核心层集聚特征明显,圈层分异特征明显。从中级尺度来看,10年间除了上海的高速增长外,最主要的特征是苏州的高速增长,其年均增长甚至超过上海,此外,苏中三市人口减少形成了长三角北翼的人口塌陷区。从微观尺度而言,上海及其周边增长快速,人口增长主要分布在核心城市构成的廊道上,各个城市核心区集聚效应明显,表明各城市仍处于向心城市化阶段。未来,根据长三角的发展特征以及国家的宏观政策,长三角的次核心城市将进一步发展,长三角人口分布的多中心趋势将会显现。
[Abstract]:Based on the data of 5th and 6 censuses, the spatial distribution characteristics of population in the Yangtze River Delta have been analyzed from three scales, namely, the circle scale, the prefectural scale and the county scale, and the population scale of the Yangtze River Delta has been further expanded during the past 10 years. The population density is further dense, reflecting the increasing capacity of population agglomeration as the economic growth pole of our country. From the point of view of the changes in the circle layer, the characteristics of population agglomeration to the core layer are obvious. The characteristics of stratigraphic differentiation are obvious. In addition to the rapid growth in Shanghai in the past 10 years, the most important feature is the rapid growth of Suzhou, whose average annual growth is even higher than that of Shanghai. In addition, The population reduction in the three cities of central Jiangsu formed the population collapse area in the north wing of the Yangtze River Delta. On a microscopic scale, Shanghai and its surrounding areas grew rapidly, the population growth was mainly distributed on the corridors of the core cities, and the agglomeration effect of the core areas of each city was obvious. In the future, according to the development characteristics of the Yangtze River Delta and the macro policy of the country, the sub-core cities of the Yangtze River Delta will develop further, and the multi-center trend of population distribution in the Yangtze River Delta will appear.
