成渝地区双城经济圈县域尺度城镇化监测与评估10年间隔数据集（2010年-2020年）

2010年—2020年成渝地区双城经济圈县域尺度城镇化监测与评估10年间隔数据集，该数据能够直观的体现2010年底及2020年底成渝地区双城经济圈县域尺度城镇化基本情况。本数据从人口、经济、社会、土地、生态五个方面综合评估城镇化，其中人口数据是基于1km*1km人口密度数据校正市级常住人口数据统计得到县级常住人口数据；经济数据则主要通过500m*500m夜间灯光数据校正市级GDP统计得到县级GDP值；社会数据是基于POI数据统计得出；土地数据是通过提取30m*30m的土地利用数据中的县域建设用地以及县域总面积之比得出；生态数据是通过提取30m*30m的土地利用数据中的县域森林、灌木、草地、水体、湿地面积以及县域总面积之比以及县域NDVI相加归一化得出。10-year interval dataset of urbanization monitoring and assessment at the county scale in the Chengdu-Chongqing Twin-City Economic Circle from 2010 to 2020. This dataset can intuitively reflect the basic urbanization situation at the county scale in the Chengdu-Chongqing Twin-City Economic Circle by the end of 2010 and 2020. This dataset comprehensively evaluates urbanization from five dimensions: population, economy, society, land, and ecology. Specifically, the population data is derived by correcting municipal permanent population statistics using 1km×1km population density data to obtain county-level permanent population figures; the economic data is mainly obtained by correcting municipal GDP statistics using 500m×500m nighttime light data to derive county-level GDP values; the social data is calculated based on POI data; the land data is calculated by extracting the ratio of county-level construction land to the total county area from 30m×30m land use data; the ecological data is obtained by normalizing the sum of two components: the ratio of county-level forest, shrub, grassland, water body and wetland area to the total county area extracted from 30m×30m land use data, and the county-level NDVI.
