Eco-environmental quality assessment based on pressure-state-response framework by remote sensing and GIS

Ecological environment quality assessment (EEQ) is an important parameter for sustainable development and sometimes it's more valuable during industrialization and urbanization progress of the region. This study compares remote sensing ecological index (RSEI) and ecological index (EI) and assesses EEQ with the most popular pressure-state-response (PSR) method based on a set of remote sensing and statistical indexes through a weight system in Samara region Russia. EI and RSEI framed from 15 toand 4 indicators respectively and in the PSR framework natural-human pressure and health state assessed based on 12 and 3 indicators respectively and in the last response index developed from pressure and state indicators. Results indicate that RSEI and EI showed very strong comparability in the ecological sense but EI reflect more effectively EEQ changes than RSEI. Finally this study explores all important effective indicators developed from remote sensing for eco-environment quality assessment, which provide a strong decision making base for sustainable development as well as provide a new and latest technological support for long term comprehensive mapping, monitoring and assessment of environment.
