Observational analysis shows vegetation dynamics influenced by climate variability, indicating key roles of temperature and precipitation in productivity.
Key Points
Vegetation productivity is sensitive to climate variability, particularly in Mongolia's northern forests and eastern steppes.
Mean annual air temperature increased by 0.94 °C, with most warming observed in March at over 1.5 °C per 10 years.
Correlation analysis revealed temperature primarily drives spring growth (r = 0.68), while precipitation influences summer growth (r = 0.30).
The results support the idea that both temperature and precipitation significantly impact NDVI and GPP in seasonal contexts.
