Evaluation and Analysis of the Impact of Coastal Urban Impervious Surfaces on Ecological Environments

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Urbanization as a human activity alters the surface structure, modifying the urban ecological environment. In this study, the greenness, wetness, building index, and heatness of Dalian, a coastal city in northeast China, were extracted from the summer MODIS remote sensing data of 2010 and 2022, and the remote sensing ecological index (RSEI) was created
