基于Matlab曲线拟合的山东省各地市人口密度预测及Cartogram地图表现

通过Matlab软件的曲线拟合功能,以1993-2012年《山东省统计年鉴》中的人口统计数据为基础数据,对山东省17地市分别选择最佳拟合模型进行人口规模预测,依据行政区划面积计算人口密度,对结果以Cartogram的技术方法进行地图表现,得出直观的结果.该研究采用了新颖的专题地图表示方法,丰富了人口预测方法,对了解未来社会的供求关系和人口发展趋势、拟定正确合理的人口规划方案具有重大的理论和实践意义.

Prediction of Population Density for Cities in Shandong Province and Map Displays of Cartogram Based on Curve Fitting of Matlab

Through the curve fitting function of Matlab software, this paper chose the best fitting model to predict the population scale for 17 cities in Shandong Province respectively based on the population statistical data of statistical yearbook of Shandong Province in 1993 - 2012 years. Then cal- culated the population density according to the administrative area. In the end, expressed the result with the method of cartogram to get visual image. This study used a novel representation of thematic map, which enriched the study of population prediction methods. At the same time, it had the great theoretical and practical significance to understand the relationship between supply and demand and the population development trend of the future so- ciety, and to scheme a reasonable population planning.
