Evolvement and Comparative Analysis of Population Gravity Center and Economic Gravity Center in Qinhuangdao City Based on GIS

Abstract:

Taking the conception and model of the regional gravity center and adopting the population and economic data of every county or district in Qinhuangdao city from 2000 to 2012, this paper calculated the population gavity center and the GDP gravity center yearly, and maked the space evolution map of the population gravity center and the GDP gravity center based on ArcGIS 10.0 software. The results show that the population gravity center and the GDP gravity center both are located in the southeast of the geometric center from 2000 to 2012. The population gravity center slowly moves to northeast, while the GDP gravity center moves to northwest. This indicates that the distribution of population and economy is disequilibrium, and the imbalance is biger in the east-west direction than south-north direction. The offset distances of the GDP gravity center relative to the population gravity center decrease both in longitude and latitude during the 2000-2012 time period, which indicates that the economic development of Qinhuangdao city is gradually moving towards balanced development.
