Abstract

In recent years, extreme climate events have occurred frequently, and extreme compound events often pose greater threats to ecosystems than single disasters. This study analyzed the impact of compound dry heat events in Inner Mongolia from 1982 to 2020 on vegetation, as well as the impact of drought events on vegetation phenology. This study constructed the Standardized Precipitation Evapotranspiration Index (SPEI) and Composite Dry Heat Index (CDHI), and explored the effects of dry heat events and drought events on vegetation and vegetation phenology in Inner Mongolia, as well as the contributions of teleconnection factors. The results indicate that: (1) Dry heat events have a significant negative impact on grasslands, especially more fragile desert grasslands and typical grasslands, and have a certain positive effect on forests. Grasslands respond more quickly to compound dry heat events. The impact of Pacific Decadal Oscillation (PDO) on the relationship between dry heat events and vegetation is most significant. The results of this study provide a foundation for improving disaster warning systems, developing targeted mitigation strategies, and protecting fragile ecosystems.
