基于作息空间思想的人口统计数据空间化方法

探讨了基于作息空间思想的人口统计数据空间化方法。定义居住和工作的活动空间范围为作息空间,并结合土地利用类型数据和泰森多边形构建了作息空间,以作息空间人口密度作为人口空间分布的表达方式。对辽宁省2005年人口统计数据进行了实例分析,精度优于传统的面积权重内插法,结果的地图渲染能够表现受自然因素和社会经济因素影响的人口分布特征。该方法不涉及复杂的权重计算过程,也可以避免主观因素的干扰,简单易行,有较强的实用性。

Spatialization Method of Demographic Data Based on Work and Residence Space Conception

The spatialization method of demographic data based on work and residence space conception is discussed in this paper.Work and residence space is defined by the extent of work and residence places,and it is created by land use data and Thiessen polygons,then population space distribution can be expressed by the population density in work and residence space.The empirical analysis is done using demographic data of Liaoning Province in 2005,result accuracy is better then area weighting interpolation method,and the result map can present the demographic characteristics affected by natural factors and socio-economic factors.This method does not include complex weights calculation procedure,it is not interfered by subjective factors,and it is simple and practicable.
