Abstract: Based on the phenological observations of six woody plant species in three stations in the period of 1983?2016, characteristics of phenology and temperature and their relationship were studied in different period. The results showed that: (1) both annual and seasonal temperature increased significantly during the study period. The warming trend was more obvious in the lower altitude areas such as Yudu, especially in Spring. Monthly temperature also increased in most areas except Xixian. Monthly temperature had increased more obvious in March, resulting increased yearly temperature. (2) Variations of phenological phase up to 1?2 months were observed in different areas and for different plants. The phenological stage happened earlier (later) in spring and ended later (earlier) in fall, leading to longer (shorter) growth stage, in Yudu and Anze (Xixian) with lower (higher) altitude. (3) The start of leaf-out had been occurring earlier in spring corresponding to higher yearly and spring average temperature, and the higher temperature a month before for all woody plant. End of leaf fall had been postponed in response to the higher yearly and fall temperature, and the temperature a month ago in Yudu and Anze but not in Xixian, where the plants were located in the highest land in three stations. The study showed the obverse variation of temperature change in three different stations. The responses of woody plants to climate change were different.
