| Abstract: |
| 【Objective】This study aims to analyze the impact of vegetation stability on water storage and meteorological factors in the Mongolian plateau.【Method】The analysis was based on data measured from 2002 to 2015. The GIMMS NDVI, monthly total water storage anomaly (TWSA), temperature, rainfall, and the autoregressive model was used to quantify the short-term impact of vegetation stability on TWSA and meteorological factors. 【Result】The vegetation index NDVI in the plateau exhibited a strong correlation with temperature and precipitation. The areas that have strong correlation between NDVI and TWSA are primarily located in the central areas in the plateau. Most vegetation types show strong stability resilience, particularly in the northeast, north, and center of the plateau. Woodland, meadow steppe, and typical grassland exhibited strong stability resilience. Most areas showed insignificant stability resistance to TWSA, and only 33.1% of vegetation exhibited strong stability resistance to TWSA. The areas with significant vegetation stability resistance were in the center, the east, and typical grassland and desert steppe areas in the Northwest. 【Conclusion】 The autoregressive model effectively represents the response of vegetation stability to water storage and meteorological factors in the plateau. The combined influence of precipitation and temperature plays a significant role in vegetation growth; areas with high water storage have a greater impact on vegetation in the plateau. |
