摘　　要：人口密度是识别人口空间分布特征的重要视角,基于网络覆盖数据进行人口分布研究是一个新的方向突破,有利于更加精细化刻画城市人口分布.基于西安市宽带覆盖数据,运用地理分析方法对西安市主城区人口空间特征进行分析,并通过研究得出以下结论:(1)人口空间格局中,西安市各等级人口密度表现出显著连片式空间分布格局,人口分布具有较强的向心性.(2)西安市人口分布具有显著的空间分异特征,不同区县、街道人口空间密度分布差异较大,人口高密度区主要集中在古城墙外围附近.(3)经济、政策因素对西安市异常人口高密度点密切相关,影响了内部人口分布.综上所述,通过对西安主城区人口空间分布特征及其影响因素的研究,对于优化西安城市空间布局具有重要理论和实践意义.Population density is an important perspective to identify the characteristics of population spatial distribution.Research on population distribution based on network coverage data is a new breakthrough,which is conducive to more refined description of urban population distribution.Therefore,in this paper,based on the broadband coverage data of Xi’an,the geographic analysis method is used to analyze the spatial characteristics of the population in the main urban area of Xi’an,and the following conclusions are drawn through research.(1)In the population spatial pattern,the population density at all levels in Xi’an shows a significant contiguous spatial distribution pattern,and the population distribution has a strong centripetal character.(2)The population distribution in Xi’an has a significant spatial differentiation feature.The spatial density distribution of the population in different districts,counties and streets varies greatly.The high-density population areas are mainly concentrated around the ancient city wall.(3)Economic and policy factors are closely related to the abnormal population highdensity points in Xi’an,which affects the internal population distribution.To sum up,the study of population spatial distribution characteristics and its influencing factors in the main urban area of Xi’an has important theoretical and practical significance for optimizing the urban spatial layout of Xi’an.
