| Abstract: | The long-term change characteristics of air temperature, precipitation, evaporation, dry/wet index in Duolun County, Inner Mongolia are analyzed by time serials based on the meteorological data observed from 1961 to 2005. The results show as follows. The annual mean air temperature has a rising of tendency,that of precipitation has a fluctuation of tendency and it is concentrated in summer. The annual evaporation is generally in an decrease trend and it is stable on the whole. There is a trend of getting wet,it is demonstrated by the changes of wet/dry index. The climate in Duolun County becomes wormer and wetter in recent 50 years. |
