Abstract：Remote sensing technology is an important means to monitor the dynamic changes of the ecological environment and evaluate the quality of the ecological environment.Based on the moderate resolution imaging spectrometer(MODIS)dataset and cloud computing technology,the paper used the optimized and improved remote sensing ecological index(RSEI)to evaluate the ecological quality of Gansu Province from 2005 to 2022 in a long series,and obtained the provincial normalized RSEI in 2005,2010,2015,2020,and 2022,and carried out qualitative analysis.The results showed that the ecological quality of Gansu Province showed an overall upward trend,and the ecological quality of the southeastern and southwestern mountainous areas was significantly higher than that of other regions.
