2015年中国人口空间分布公里网格数据集
收藏资源简介:
中国人口空间分布公里网格数据集是在全国分县人口统计数据的基础上,综合考虑了与人口密切相关的土地利用类型、夜间灯光亮度、居民点密度等多因素,利用多因子权重分配法将以行政区为基本统计单元的人口数据展布到空间格网上,从而实现人口的空间化。最终根据上述方法得到1km网格的人口空间分布数据,该数据集反映了人口数据在全国范围内的详细空间分布状况。
The 1-kilometer Population Spatial Distribution Grid Dataset of China is developed based on national county-level population statistical data. It integrates multiple factors closely correlated with population, including land use types, nighttime light brightness, and settlement density. The multi-factor weight allocation method is applied to disaggregate the population data, which takes administrative divisions as the basic statistical units, onto spatial grids, thereby achieving the spatialization of population data. Ultimately, the 1-kilometer grid population spatial distribution data is generated via the aforementioned method, and this dataset reflects the detailed spatial distribution of population at the national scale.
