Abstract: Changes in biodiversity and their driving mechanisms are of great significance to the development of biodiversity conservation measures.Remote sensing technology has outstanding advantages in large-scale and long time-series research.In order to grasp the spatial pattern and time-series changes of animal diversity in the Yellow River basin,this study utilizes the time-series Landsat and MODIS satellite image data from 2000 to 2022,and combines the GEE,InVEST model,and GIS-related technologies to construct an index for assessing the animal diversity in the Yellow River basin based on 7 indicators in 2 aspects:species diversity and ecosystem diversity.The animal diversity assessment index of the Yellow River basin is constructed based on seven indicators of species diversity and ecosystem diversity,and the accuracy assessment is carried out based on the measured data,and the analysis of the driving factors is also carried out.The results show that:the BI constructed in this study had high precision,and the correlation with the measured species data is 0.80; the BI in the Yellow River basin shows an overall increasing trend during the 22 year perios; the area of the BI increases accounted for 70.63%of the total area,and the area of the BI decreases accounted for 29.37%; based on the analysis of the contribution of the driving factors,evapotranspiration is the primary environmental control factor.
