The Features of climate change in Mt.Yulong, southeasten Tibetan Plateau were analyzed using linear regression, MannKendall abrupt test and Morlet wavelet analyses. In addition, the relationship between glacier retreating (Baishui Glacier No.1) and climate warming wasalso analyzed in this study. The main results are showedas follow: ① The annual mean temperature, precipitation have an increasing trend, withinclination rates being 0.15℃/10a and 9.0 mm/10a;annual temperaturedramatically ascend in 1998 with the change values 0.7 ℃; Morlet waveletsin annual temperature andtemperature in dry season mainly have a 10 to 15year periods,while annual precipitation amount and the precipitation in rainyseason presented a quasi 10 year periods. ②Prior to 1998, the important meteorological factor influencing the change of Baishui Glacier No.1 are temperature and precipitation, while in the following years, temperature plays a more important role in affecting its retreat and advance; The main characteristic ofverticalclimate change in Mt. Yulong (1982/2009) is that the cold season shortens and temperature rises with elevation, and the maximal value of increased temperature in glacier zone is 2.2~2.5 ℃, resulting in greatly accelerated glacier ablation.
