摘要
探讨人口与经济重心空间演变规律,以及二者空间演变的影响因素,为西安市制定合理的城市建设和发展政策提供理论依据。以西安市作为研究区域,采用GIS空间分析方法模拟2000—2011年间人口重心和经济重心的空间演变轨迹,分析二者迁移变化的规律、时序及相互间作用关系。得出人口和经济重心的移动具有同向性,并与城市发展方向基本一致;同时,人口重心变动相对于经济重心具有滞后性。并据此推断西安市未来人口和经济重心将继续向北部地区移动;未来的城市建设和发展规划必须重视北部地区的开发建设,加强北部地区城市设施建设配套。
The purpose of this paper is to discuss population and economy center space evolution law and effects of these two migrations, and then to provide a theoretical basis for making reasonable urban construction and develop- ment policy of Xi'an. Using Xi'an as the research area, the GIS spatial analysis method is used to simulate popula- tion or economy gravity center in space variable trajectory from 2000 to 2011 and analyze the rules of migration, timing and mutual interaction relations between these two trajectories. Population gravity center and economy gravity center move in the same direction and keep the same development direction with urban development. Meanwhile, population gravity center lags behind the economy gravity center. Urban population and economy gravity center in Xi'an will continue to move north ; the urban construction and development planning of the future must attach much importance to the development and construction in the north and strengthen the construction of northern city facili- ties.
