基于土地利用类型数据的统计人口空间化模型研究:以福建省为例

Research on statistical population spatialization model based on land use type data: An case study of Fujian Province

  • 摘要: 文章基于福建省土地利用类型数据进行县级统计人口的空间化,比较分区人口空间化模型与不分区人口空间化模型及不同格网大小的人口空间化精度,探讨基于土地利用类型数据的统计人口空间化模型合理性及合适空间化尺度. 结果表明:采用不分区建模的方法进行人口数据空间化,最适宜的格网尺度为6 km,其格网人口抽样精度为62.12%;采用分区建模的方法进行人口数据空间化,最适宜的格网尺度为3 km,其格网人口抽样精度为84.41%. 鉴于此,对于福建省当前的人口空间分布,采用分区建模后3 km格网尺度的人口空间分布,能够较精确地反映各县市真实的人口分布情况.

     

    Abstract: Based on the land use type data of Fujian Province, the spatialization of county-level statistical population is conducted in this article. Then the rationality of the spatial model and the appropriate spatialization scale are evaluated based on land use type data, by comparing the spatialization models of partition population and general population, and comparing the spatialization precision of population with different grid sizes. The results show that when the population data is spatialized by the method of gengral modeling, the most suitable grid size is 6 km, and the sampling accuracy of the grid population is 62.12%; when the population is modeled by partition modeling, the most suitable grid size is 3 km, and the sampling accuracy of the grid population is 84.41%. Therefore, the spatial distribution of population with 3 km grid scale after partition modeling can accurately reflect the population distribution at county level in Fujian Province.
