Abstract:

Based on the Terre-MODIS NDVI and GIMMS NDVI data, we used the deep learning super-resolution algorithm to generate the 250 m resolution NDVI datasets of 1990, 2000, 2010, and 2020 in China. By superimposing the physical space of urban built-up areas in different periods, the NDVI data within the physical boundary of cities were extracted, and the average NDVI within the administrative scope and physical scope of 361 Chinese cities in 1990, 2000, 2010, and 2020 were calculated respectively. The dataset showed that the NDVI in the whole country and the urban area of China decreased first and then increased, but there was significant spatial heterogeneity. This dataset could support urban eco-environmental governance, urban green space planning and construction, ecological environment policy formulation, and government performance evaluation, and can also be used as basic data for the study of ecosystem evolution driven by urbanization and climate change. The dataset is archived in .tif and .xlsx formats with a spatial resolution of 250 m, and consists of five data files with 6.51 GB (compressed into five files with 1.83 GB). The analysis paper was published at Ecological Indicators, Vol. 147, 2023.Browse
