2026-08-17 Measurement of urbanization and ecological resilience of the Jiangsu-Anhui-Shandong-Henan interprovincial border region doi:10.57760/sciencedb.cje.00005 en The socio-economic data such as urban population density and per capita GDP are from the China Urban Statistical Yearbook(2000-2023) and the statistical bulletin of each city. The ecological environment data such as the green coverage rate of the built-up area and the per capita park green space area are from the Statistical Yearbook of Urban Construction(2000-2023). Energy consumption data such as per capita emissions of three industrial wastes are from the China Energy Statistical Yearbook(2000-2023). The nighttime light mean value of the construction land is obtained from the remote sensing image processing of the National Earth System Science Data Center( http://www.geodata.cn). Among them, the DMSP/OLS images from 2000 to 2013 are not subject to on orbit radiometric calibration, so a binary quadratic equation is established to correct each other, and the continuity correction of sensor images and time series are carried out respectively; NPP/VIIRS images from 2012 to 2023 include transient fire light, fishing boat light and other unstable light sources, so they are removed by threshold method; For the spatial differences between the two types of remote sensing images, the logarithmic transformation method is used to convert the VIIRS observation value into NTL data similar to DMSP, and its resolution is corrected to be the same. Finally, based on the overlapped image data, the power function model is constructed with the pixel values of the invariant target area as samples, and the pixel values of the cross sensor time series are converted consistently. Then the nighttime lighting data set of the study area from 2000 to 2023 is obtained. The total carbon emissions of each city are extracted by the EDGAR(2025_GHG) database(https://edgar.jrc.ec.europa.eu). The number of patent applications and authorizations comes from the patent retrieval platform of the State Intellectual Property Office, and the green invention data is screened according to the Classification System of Green Technology Patents issued by the State Intellectual Property Office in 2023. ecological resilience; urbanization; measurement analysis Chen Mingjie Ou Xiangjun Yang Zhen RESTRICTED dataset Science Data Bank
