Abstract: Based on phenological data of the woody, herbaceous plants and observed temperature data in agricultural experiment station of Yuncheng, Linfen, Jincheng and Changzhi, Shanxi province, the variation of temperature and phenology was analyzed by using the methods of anomaly analyzing and linear tendency, and the effect of the climate warming on phenological plants was discussed. The results showed that all of the phenology in spring advanced, and plant growing season prolonged. Phenophase in autumn delayed, but the beginning of leaves falling for most herbaceous plants advanced a little, and the end of leaves falling for most the herbaceous plants advanced. The leaf expansion date advanced 1-18 days with l℃ increasing.
