Evaluation of Ecological Environment Quality and Analysis of Influencing Factors in Anshan City Based on Remote Sensing Ecological Index
Understanding the temporal and spatial changes of ecological environment quality will provide data reference for the future ecological environment management and mining area restoration in Anshan City.In this study,Landsat data was used to construct the remote sensing ecological index model(RSEI)of Anshan City in 2017,2020 and 2023,and Moran index,geographical detector and other methods were used to explore the driving factors of ecological environment change.The results show that NDVI and WET have a positive impact on the ecological quality,while NDB-SI and LST have a negative impact.The ecological environment quality of the City is spatially correlated,and RSEI has a significant aggregation state.From 2017 to 2023,the ecological environment quality remained basically stable.The area of the same type of ecological environment quality accounted for 90.40％,and the area with excellent ecological grade ac-counted for more than 55％of the total area.The ecological quality of Xiuyan County was the best,and the ecological quality in the main urban area was the best in Qianshan District.The influence of each factor on the quality of the eco-logical environment is quite different.The heat is the main driving factor,and the explanatory power is stronger after the factor interaction.The land use types are mainly cultivated land and forest land.The area of cultivated land trans-ferred to forest land,grassland and construction land is gradually increasing,which increases the area of regional vegeta-tion coverage and promotes the improvement of regional ecological environment quality.The research shows that Anshan City needs to increase vegetation coverage and accelerate mine restoration efficiency in the future to improve the ecolog-ical environment quality.
