吉安市人口集聚格局研究

Study on the Population Agglomeration Pattern of Ji′an City

人口集聚格局是人口空间分布最直观的体现,是人口研究热门主题之一。其研究结果有利于深入解析研究区的整体人口分布特征和规律,准确把握人口空间分布的基本脉络,为引导人口的合理流动、制定区域人口政策等提供依据。采用人口集聚度方法及结合GIS技术,探讨吉安市人口空间分布的基本规律和特征。研究结果表明:21世纪以来,吉安市人口空间分布呈现不均衡的趋势,人口分布大的格局基本未发生太大变化,基本格局还是"市域中部吉泰盆地密集西南及东南山区稀疏",在此基础上形成吉泰走廊区、京九铁路及赣江干流沿线平原区、市域西部罗霄山脉及东部雩山山脉区等三大人口梯度区。

The population agglomeration pattern is the most intuitive embodiment of the spatial distribution of population,and it is one of the hot topics in population research.The results of the study are conducive to in-depth analysis of the overall population distribution characteristics and laws of the study area,accurately grasp the basic context of population spatial distribution,and provide a basis for guiding the rational flow of population and formulating regional population policies.The population agglomeration method and GIS technology were used to explore the basic rules and characteristics of the spatial distribution of population in Ji’an City.The research results show that Since the 21 st century,the spatial distribution of population in Ji’an City has shown an uneven trend,and the pattern of large population distribution has not changed much.The basic pattern is still"dense southwest and sparse mountainous areas in the Jitai Basin in the central city".Corridor area,plain area along the Beijing-Kowloon Railway and the main stream of the Ganjiang River,the Luoxiao Mountains in the west of the city and the Laoshan Mountains in the east have three major population gradient areas.
