By means of the methods of moving average, trend analysis, wavelet transform, MannKendall and Yamamoto tests, the climate change characteristics in the recent 50 years are analyzed based on the precipitation and temperature data of the Zhalong wetland from 1955 to 2004. The main results indicate: (1) Annual mean temperature and seasonal mean temperature appear to be ascending; annual mean temperature had a sudden change in 1988, and since then a warmer period appeared; the period from the 1990s to date is the warmest in recent 50 years. (2) Annual precipitation and seasonal precipitation all show a decreasing trend except in spring, especially remarkable in fall; there was no obvious sudden change during the concerned time period. (3) After 1985, the frequency and intensity of summer and warm winter events conspicuously increased and atmospheric moisture decreased; there is a warming trend in the Zhalong wetland.
