详细信息   
摘要


     The variation characteristics of air temperature,precipitation,sunshine duration and its effect on five species of woody plants such as Populus bolleanalanche, Salix babylonica,Prunus armeniaca,Malus pumila,Fdeagnys qxycarpasehlech commonly in Kashi were investigated using by climate trend coefficient and climate tendency ratio based on meteorological observational data and phenological observation data of ground in the national reference stations from 1982 to 2010 of Kashi39°28N,75°59E.The results show that in the past 29 years the climatic was warming and the basic meteorological elements such as air temperature,precipitation and sunshine duration were increased significantly, the increasing rate of annual average temperature and total rainfall were 0.37-1.10/10a and 12. 14mm/10a respectively.For as season,temperature and sunshine duration were increased significantly in spring and precipitation was obviously in autumn.The climatic warming was related to the phenology of five species of woody plants that increasing of spring temperature and sunshine duration were advances of plant phenology,and precipitation in the autumn to promote the woody plants growth and lead to delay of the plant phenology.
