摘　　要：本文基于西安市各区县2000—2013年的人口数据,将空间统计分析同GIS相结合,探讨2000—2013年西安市人口空间分布的演变过程。研究表明:(1)西安市总人口数在不断增加,其中流动人口增长是主要因素;(2)西安市各区县人口增长速度不尽相同,呈现出中心"弱化"、郊区"增强"和边缘县"不振"的变化态势;(3)西安市人口分布具有显著的空间集聚性,且集聚作用仍在不断增强。因此,建议:(1)优化人口与经济结构,增强城市CBD人口与经济集聚能力;(2)远郊三区和边缘四县重点发展特色优势产业,加快推进新型城镇化步伐。This article is based on demographic data in different districts of Xi ’ an City from 2000 to 2013 .In the paper , spatial statistical analysis and GIS are combined to analyze the spatial evolution of population distribution in Xi ’an City in the past 14 years.Results are as follows:(1) The total popula-tion continues to grow in Xi ’ an city and the main factor is increasing floating population .( 2 ) Growth speed is different among 13 districts of Xi ’ an City , and some characteristics of population distribution have presented:“decreasing” in the urban centre , “boosting” in the outskirt and “sluggish” in the fringe counties.(3) Population distribution in Xi ’ an City significantly shows space accumulation , and this force is continuously deepening .Therefore, we recommends:(1) The spatial structure of the popu-lation and economy should be optimized to improve the city CBD ’ s population and economic concentra-tion ability;(2) The three suburban districts and the four edge counties should develop specialty indus-tries with local advantages and thereby promote the pace of new urbanization .
