基于改进型遥感生态指数的南昌市生态环境评价
Evaluation of ecological environment in Nanchang City based on improved remote sensing ecological index
摘要
Abstract
Based on Landsat data from 2016 to 2022,this paper used two traditional remote sensing ecological index(RSEI)models and the improved RSEI model to calculate the RSEI.It analyzed the spatio-temporal variation of ecological environment quality in Nanchang City at the county and district levels.The geophysical detector was used to explore the driving factors that affected the ecological environment quality and their interactions.The results show that:① Temporally,the RSEI of Nanchang City from 2016 to 2022 shows a trend of first increasing and then slightly decreasing,indicating that the ecological environment becomes better and then slightly worse.② Spatially,the ecological environment quality from 2016 to 2022 is dominated by the general grade and above,and the RSEI value generally shows the spatial differentiation characteristic of low in the middle areas and high at the edges.③ The geophysical detector analysis shows that urban ecological construction and human activities have an important impact on the ecological environment quality in Nanchang City.Therefore,Nanchang City should pay more attention to balancing economic construction and ecological environmental protection in future policy planning,so as to achieve coordinated development of ecology and economy.关键词
