摘要：Tea (Camellia sinensis (L.) Kuntze) plantation represents one of the most important artiffcial vegetation types in the subtropical–warm temperate climate transition zone of China. Soil drought stress is an important factor limiting the growth of tea plantation, but its long-term evolution characteristics and relationship with climate change have yet to be quantitatively analyzed. In this study, we employed the Biome-BGCMuSo model to simulate ecohydrological dynamics over the past 60 years (1961–2020) for tea plantations in the climate transition zone. The long-term evolution of soil drought stress was analyzed based on the annual and seasonal average soil drought stress index (AveSDSI). The relationships between the interannual trends and ffuctuations of AveSDSI with climate factors were further examined through factorial simulations and partial correlation analysis, respectively. The results indicated the Biome-BGCMuSo model effectively simulated the soil moisture dynamics in tea plantations in the study area. From 1961–2020, annual and seasonal AveSDSI both exhibited increasing trends, with a signiffcant linear relationship between spring AveSDSI and time. The 11-year moving standard deviation of both annual and spring AveSDSI showed signiffcant increasing trends, indicating intensiffed interannual ffuctuations in soil drought stress. Factorial simulations and partial correlation analysis revealed vapor pressure deffcit (VPD) and precipitation were the primary factors inffuencing the interannual variability of AveSDSI, respectively dominating the interannual trend and ffuctuation of annual AveSDSI. Notable seasonal differences were also evident. These ffndings provide an important foundation for optimizing management and disaster mitigation for tea plantations in the climate transition zone.
