摘　　要：为深入探析快速城镇化背景下我国城市内部人口空间格局发展的科学规律,助力新时期长沙市人口政策和发展规划的合理制定,文章基于第六次、第七次人口普查数据,采用反距离权重法、人口重心及标准差椭圆等方法,研究2010—2020年长沙市人口增长与空间分布的演化特征及趋势。研究发现:(1)长沙市人口规模增长迅速,主城区人口集聚水平显著提升,老龄化速度低于全国平均水平,平均受教育程度显著提高。(2)依据人口增长情况可将长沙市各街镇分为高速增长、稳定增长、低速增长和负增长四种类型,岳麓区、望城区以高速、稳定增长型街镇为主,雨花区、天心区、开福区、长沙县各类型街镇分布较为均衡,宁乡市、浏阳市、芙蓉区则以低速增长和负增长街镇为主。(3)长沙市人口重心向西南方向移动,南部、西部成为城市人口增长的主要方向。(4)长沙市人口密度空间分布格局总体呈“单中心+双组团”结构特征,同时老城人口密度呈下降趋势,中心区扁平化扩张明显。To deeply explore the scientific laws governing the development of the spatial pattern of urban population in China under the background of rapid urbanization,and to assist in the reasonable formulation of population policies and development plans for Changsha in the new era,this study,based on the data from the sixth and seventh national population censuses,employs research methods such as the inverse distance weighting method,population gravity center,and standard deviation ellipse to investigate the evolutionary characteristics and trends of population growth and spatial distribution in Changsha from 2010 to 2020.The study finds that:1)The population size of Changsha is growing rapidly,with a significant increase in population agglomeration in the main urban area,an aging rate lower than the national average,and a significant increase in average education level.2)Based on population growth,Changsha's each street and town can be divided into four types:high-speed growth,stable growth,low-speed growth,and negative growth.Yuelu District and Wangcheng District are dominated by high-speed and stable growth street towns,while Yuhua District,Tianxin District,Kaifu District,and Changsha County have a more balanced distribution of various types of street towns.Ningxiang City,Liuyang City,and Furong District are dominated by low-speed growth and negative growth street towns.3)The population gravity center of Changsha has moved towards the southwest,with the south and west becoming the main directions for urban population growth.4)The spatial distribution pattern of population density in Changsha generally exhibits a"single center+dual clusters"structural feature,with a downward trend in population density in the old city and a noticeable flat expansion in the central area.
