Based on the time series of daily average air temperature and sunshine duration of Guizhou Province from 1951 to 2010, the average air temperature and annual sunshine duration was calculated by using the methods of Mann-Kendall abrupt change test, wavelet analysis and moving average method to analyze the climatic trend rate and saptial-temporal characteristics of temperature and sunshine duration of Guizhou Province. The result showed that, the average air temperature of Guizhou has witnessed a

The sunshine duration of Guizhou climbed in the 1960s and started to decline since 1970s. However, the sunshine duration showed an increasing trend in the past 10 years. Different with the spatial distribution of air temperature, the sunshine duration of southwest area is more than the north-west area.
