2020年四川省常住人口分布数据集

数据文件名称：2020年四川省常住人口分布数据集，该数据严格按照相关数据处理标准进行生产，以栅格TIF格式保存，数据精度为1km*1km，投影坐标系为Krasovsky_1940_Albers。为相关研究人员提供精细化的四川省常住人口空间分布情况。本数据：首先基于1km*1km的联通用户手机信令数据源，以联通手机用户是否于夜间休息时间段15天以上在同一联通通讯基站服务范围内存续为依据，判定是否为该基站服务范围内的常住人口，得到大区域准确与精细的常住人口空间分布规律，其次基于常住人口空间分布规律使用地级市统计年鉴数据对常住人口进行量级校正，最后获得1km*1km栅格的常住人口空间分布数据。

Data File Name: 2020 Sichuan Province Permanent Population Distribution Dataset. This dataset is developed strictly in accordance with relevant data processing standards, stored in raster TIF format, with a spatial resolution of 1km×1km, and uses the Krasovsky_1940_Albers projected coordinate system. It provides researchers with refined spatial distribution data of the permanent population in Sichuan Province. The data production process is as follows: First, based on the 1km×1km mobile signaling data of China Unicom users, we determine whether a user is a permanent resident within the service scope of a communication base station by verifying if the user has stayed within the coverage for more than 15 days during the nighttime rest period, thus obtaining the accurate and fine-grained spatial distribution pattern of permanent population across large regions. Second, we perform magnitude calibration on the permanent population counts using prefecture-level city statistical yearbook data based on the aforementioned spatial distribution pattern. Finally, the 1km×1km raster spatial distribution dataset of permanent population is obtained.
