顾及城乡差异的大区域人口密度估算——以山东省为例

现有大区域人口密度估算结果大多是在千米级尺度上,仅能宏观地反映城乡人口分布的范围,无法准确地刻画城乡人口空间分布的细节特征。本文将首套30m全球地表覆盖数据（GlobeLand30）引入城乡人口密度估算中,基于实现城乡划分的GlobeLand30人造地表数据,在城镇区域运用夜间灯光强度与人口的相关性将城镇人口细划到30m尺度上来估算城镇人口密度;在乡村区域引入样方估算的方法修正乡村居民地面积以估算乡村人口密度。以山东省为试验区的研究表明,本文方法无论在城乡居民地刻画还是人口空间分布的表达上均优于参考数据,所使用的GlobeLand30的全球性也保证了该方法推广的可行性。...

Summary:	现有大区域人口密度估算结果大多是在千米级尺度上,仅能宏观地反映城乡人口分布的范围,无法准确地刻画城乡人口空间分布的细节特征。本文将首套30m全球地表覆盖数据（GlobeLand30）引入城乡人口密度估算中,基于实现城乡划分的GlobeLand30人造地表数据,在城镇区域运用夜间灯光强度与人口的相关性将城镇人口细划到30m尺度上来估算城镇人口密度;在乡村区域引入样方估算的方法修正乡村居民地面积以估算乡村人口密度。以山东省为试验区的研究表明,本文方法无论在城乡居民地刻画还是人口空间分布的表达上均优于参考数据,所使用的GlobeLand30的全球性也保证了该方法推广的可行性。
Bibliography:	11-2089/P Existing methods for large regional population density estimation,which are mostly concentrated in the kilometer scale and only reflect the macro distribution characteristics of the urban and rural population,are difficult to describe details of urban and rural population spatial distribution accurately.In order to resolve the problem above,an estimation method of large regional urban and rural population density,which is based on the first 30 mglobal land cover dataset（GlobeLand30）is proposed.Based on the urban and rural area data partitioned from artificial surfaces data in GlobeLand30 datasets,the population density were estimated in urban and rural area respectively.Urban population density was estimated through the correlation between night lighting intensity and population.Through area revise of rural patches by the method of quadrats estimation,the rural population density was estimated.This paper takes Shandong province as a test area.The result shows that the method of urban-rural population
