Analysis of the Spatial and Temporal Evolution Patterns of Grassland Health and Its Driving Factors in Xilingol

The combination of natural environment changes and human activities affects the growth grasslands. In order to quantitatively assess causes spatial temporal variation grasslands in Xilingol, this study assessed evolution patterns grassland health based on MOD13A1 long time series Normalized Difference Vegetation Index (NDVI) data from 2000–2019 using trend analysis. geodetector model was used explore dominant drivers NDVI, combined with 34 factors covering environmental disturbances over same period. results show that Xilingol showed an overall recovery 2000 2019, average annual NDVI rate 0.0028/a, a monthly increasing 0.0005/month, 68.06% at level. Moisture-dominated climate change factors, such as Growing Season Precipitation (Prep2), Annual Mean Water Vapor Pressure (WVP), Relative Humidity (RH), were underlying cause during period, highest explanatory factor being growing season precipitation (q value 0.59 multi-year average). influence primary production among greater, tertiary trend. interactions anthropogenic significantly enhances their credibility for type interaction dominated by two-factor enhancement.
