Abstract: Based on the plant phenological data of 26 stations from 1963 to 1996, observed by the phenological observation network of the Chinese Academy of Sciences, changes of plant phenological period and its response to climate change were studied. The models for relationship between phenological periods in every decade and geographical location were constructed. The response of the geographical distribution of phenological period to climate change was analyzed. The results showed that the phenological periods of ligneous plant occurred earlier as the temperature in spring rises; In the Northeastern China, the North of China, and the regions of lower reaches of the Changjiang River, the plant phenological periods were earlier since 1980's. In the eastern part of the Southwest China and the regions of middle reaches of the Changjiang River, the plant phenological periods delayed as the temperature declined; Changes of phenological periods became smaller with the increasing of latitude.
