ASSESSMENT OF CHANGES IN THE QUALITY OF THE ENVIRONMENT IN THE LVIV REGION ON THE BASIS OF ENVIRONMENTAL INDICES OF REMOTE SENSING

Abstract

The ecological environment system is closely related to human daily life. With the acceleration of industrialization and urbanization, various human activities have brought great impacts on the local ecological environment. Timely and accurate evaluation of spatial and temporal changes in the quality of the ecological environment helps policy makers to understand the current status of the ecological environment in the region, and is of great significance for the rational development of ecological environmental protection and policies, which has become a research priority in the field of ecology. In this study, Lviv Oblast, an important region in western Ukraine, is taken as the study area, and the remote sensing ecological index remotely sensing ecological index (RSEI) of Lviv Oblast for 2015 and 2021 was constructed based on remote sensing technology, and the ecological quality of Lviv Oblast during six years was rapidly monitored and evaluated, and the results of the study show that the The average values of RSEI in 2015 and 2021 are 0.66 and 0.68, respectively, indicating a gradual improvement of ecological quality. This reflects the small impact of the deterioration of the ecological environment caused by human activities in the region in recent years.This study provides a methodological reference for evaluating the quality of the ecological environment in the Lviv region, which is of some value for the rational planning of local ecological and environmental protection strategies and policies for sustainable economic development.
