Dynamics of the eco-environmental quality in response to land use changes in rapidly urbanizing areas: A case study of Wuhan, China from 2000 to 2018

The dramatic land use changes that occur in rapidly urbanized areas are important inducement to the eco-environmental quality. Investigating urban and their quality responses can provide theoretical support a decision-making basis for sustainable high-quality development urbanizing areas. Taking Wuhan, China, as study area, this paper extracts information using Landsat satellite remote sensing images vector machine classification. Based on this, sensing-based ecological index evaluation model including humidity, greenness, dryness heat is constructed explore from 2000 2018. results show (1) structure, extent spatial layout of Wuhan 2018 have undergone tremendous under rapid urbanization, change construction greatest among all types; (2) overall eco-environment continues improve scale improved greater than deteriorated direction magnitude impact each indicator different; (3) improvement or deterioration closely related different types within area. shows significant heterogeneity, especially between main suburban This argues reasonably adjusting structure serve maintain even regional eco-environment. Finally, puts forward suggestions coordinated
