title: [Dynamics of autumn phenophase of woody plants in Beijing region in 1962-2007].
abstract: The responses of the autumn phenophase of 20 woody plants to climate warming in Beijing in 1962-2007 were analyzed by using the plant phenological data and the meteorological data obtained from Chinese Phenology Observation Network of Chinese Academy of Sciences. The results showed that in Beijing region, the end date of autumn defined by phenology was extended remarkably at an average rate of 3.2 d x 10 a(-1), while the onset of autumn defined by phenology remained essentially unchanged, resulting in a 14 d prolongation in autumn in 1962-2007. The timing of first leaf coloring change for the woody plants showed an average delaying rate of 4.9 d x 10 a(-1), and the main affecting factor was the mean minimum temperature. Climate warming was probably the main reason for the delaying trend in autumn phenophase of woody plants in Beijing during the study period.
