Obvious differences were observed in the increasing rate of annual mean maximum air temperature,annual mean air temperature,and annual mean minimum temperature as well as the heat island effect in Ji\'nan,whereas negligible differences were found in Xi\'an.

By using Mexican-Hat wavelet transformation,the features of annual mean temperature in the past 50 years(from 1951 to 2000) in Zhanjiang region are discussed.

Using EOF analysis,the climate accident analysis,the maximum entropy spectrum analysis,the tendency rate and other methods,the paper carries on the temporal and spatial characteristic analysis of the annual mean temperatures in 1961-2005 in Henan.

This paper has achieved some conclusions: the daily mean temperature ,the daily maximum temperature and the daily minimum temperature all increased in recent 40 years in this area.

This paper has achieved some conclusions:the daily mean temperature, the daily maximum temperature and the daily minimum temperature all increased in recent 50 years in Qinghai-Tibet plateau area.

Based on the average annual temperature,annual precipitation and no frost period data from Shihezi Meteorological Bureau during the period of 1967-2006,the climate trend was analyzed using linear fitting method,3-year smoothing average and M-K methods.

In this paper, the data of the average annual temperature, annual precipitation and no frost period,which gotten from Shihezi Meteorological Bureau during the period of 1967~ 2006, have been analyzed by linear fitting method, smooth average method of three years and M-K method to get their trend and correlation.
