人口在空间上的分布变化直接影响城市形态及其土地利用结构、基础设施建设、公共服务配置及交通、居住等多个方面。特大城市处于国家城镇体系的顶层,是重要城镇群的核心和领导城市,对外来人口具有较大的吸引力。文章在分析特大城市人口空间分布一般规律的基础上,结合人口普查数据分析天津市的人口时空分布演变特征,判断其人口分布趋势,并从区域协调发展、生态环境保护、产业布局优化、公共设施建设和外来人口市民化方面提出应对人口增长与优化人口分布的策略。
The spatial distribution of population directly affects the urban morphology and its land use structure, infrastructure construction, public service allocation and transportation, housing and other aspects. The mega-cities are at the top of the national urban system. They are the core and leading cities of important urban agglomerations, and are more attractive to the migrants. Based on the analysis of the general law of population distribution in megalopolises, this paper analyzes the evolution of population distribution in Tianjin according to the census data, and determines the population distribution trends. From the perspective of coordinated development of regions, protection of ecological environment, optimization of industrial layout, public facilities Construction and urbanization of migrant population put forward strategies to deal with population growth and population distribution optimization.
