| 英文摘要 | The temperature sensitivity of plant phenology reflects how and to what extent plants respond to climate change and is significantly related to their ability to adapt to climate change. Previous studies on the temperature sensitivity of first leaf date (FLD) primarily focus on temperate regions, with relatively few studies conducted in subtropical areas. This study analyzed observational data on the FLD of 63 typical woody plant species from 1980 to 2019 in Guiyang, located in the subtropical zone of China. We quantified the trend of FLD and its sensitivity to temperature changes and then assessed the impact of sample size on the stability of sensitivity estimates. The results showed that (1) significant warming occurred in Guiyang during the study period, with the largest warming occurring in spring. (2) The FLD of the vast majority of plants (95.2%) showed an earlier trend during the study period (19.0% significantly at p < 0.05). The earlier trend of most species ranged from -3 to -1 days decades(-1). The median of trends for all 63 species investigated was 1.97 days decades(-1). (3) The interannual variation in FLD was significantly negatively correlated with the preseason average temperature (p < 0.05). Most of the temperature sensitivity of FLD was between -5 and -3 days degrees C-1, with a mean of -4.53 days degrees C-1. (4) The sample size significantly influenced the stability of the temperature sensitivity estimates. Using randomly selected 20-year data could limit the standard deviation of the sensitivity estimate to 0.3 days degrees C-1. These results suggest that the leaf unfolding date of subtropical species could track climate warming closely like temperature species. The temperature sensitivity of FLD should be estimated based on long-term observation data. |
