Based on the daily precipitation data of Emei Mountain,Emei City,Leshan City and Jiajiang County meteorological stations from 1959 to 2016 and their hourly precipitation data during June-September from 1964 to 2016,the multiple time scale variation characteristics of the amount of precipitation,rain days and precipitation frequency in Emei Mountain and its surrounding area were studied by statistical analysis and diagnosis methods. The result shows that the decadal precipitation and rain days decrease in Emei Mountain and its surrounding area in the past few decades,and the decrease degree of high-altitude Emei Mountain is stronger than that of low-altitude surrounding area. The annual precipitation and annual rain days decrease significantly in Emei Mountain and its surrounding area after the 1990s,and the annual rain days in Emei Mountain decreases faster. In flood season, the variations of amount of precipitation and rain days in Emei Mountain and its surrounding area are stronger than their interdecadal and interannual variations,and it is more prominent than the other periods. Except in spring,the precipitation in high-altitude Emei Mountain in other three seasons reduces significantly,and it obviously reduces in summer and autumn in low-altitude surrounding area. The decrease of rain days in all seasons is more obvious in Emei Mountain than in its surrounding area. The reduction of monthly precipitation and rain days in Emei Mountain is more obvious that that in its surrounding area. The diurnal variation of precipitation in highaltitude Emei Mountain has single-peaked and single-valley distribution,but the second peak appears in the morning in low-altitude Emei City. The precipitation of Emei Mountain and its surrounding area is much larger in the night than that in the daytime. The peak time of precipitation in Emei Mountain and Emei City occurs earlier than before. The time of maximum hourly precipitation frequency has significantly advancing feature in Emei Mountain. But Emei City has the variation of being delayed. Under the global warming,the precipitation in Emei Mountain and its surrounding area significantly decreases,especially in Emei Mountain. The consistency and difference of regional climate response in Emei Mountain and its surrounding area may be related to regional temperature responses and water vapor conditions.
