As the representative of China's high-quality development, maintaining its ecological security is of great significance to China's ecological construction. Based on the remote sensing ecological index (RSEI), this paper analyzes the temporal and spatial changes of ecological quality and its influencing factors in Guangdong Province from 2000 to 2023. According to ENVI and Arcgis software, the spatial and temporal changes of ecological quality in Guangdong Province and the spatial correlation of RSEI in Guangdong Province are calculated and drawn. At the same time, R2 of OLS and MGWR models is fitted to verify the linear fitting relationship between influencing factors and RSEI in Guangdong Province. The research results show that: ( 1 ) the development of RSEI in Guangdong Province generally shows a downward trend from 2000 to 2023; ( 2 ) The change trend of RSEI in Guangdong Province is different in different periods; ( 3 ) The RSEI in Guangdong Province shows strong spatial auto-correlation; ( 4 ) The relationship between potential influencing factors and RSEI is not only positive, but also negative. Based on the above conclusions, the article puts forward corresponding policy suggestions. ecological quality RSEI Temporal and spatial evolution Spatial correlation MGWR model Full Text Additional Declarations No competing interests reported.
