Abstract: Based on the data of peach phenology and the yield in 1981-2004 and meteorological data in 1961-2005,the responses of climate change on peach growth were statistically analyzed.The results indicated that the main meteorological factors influencing peach growth were the minimum temperature from the first to the second ten days of April,the precipitation in July and August and the sunshine percentage in August.By the analysis of the characteristics of climate factors for the last 45 years,it was concluded that the warmer and drier climate resulted in the advance of the phonological period of the peach.With the increase of the freeze damage in the early spring,the planting risk of the peach increased.The decreased trend of the precipitation in July and August was favorable to the maturity of the peach,while the decreased trend of the sunshine percentage was not favorable to the peach fruit yield and quality.
