| Abstract: | Using the surface meteorological observation data of Guaizi Lake from1971 to 2010 years meteorological station, the basic characteristics of climatic change was analyzed in recent 40 years in Guaizi Lake. The results showed that： the general trend of tem- perature changes was increased in recent 40 years in Guaizi Lake, the temperature rise of spring, summer and autumn was particular- ly evident; annual precipitation was not very stable; relative htzmidity changes was less; the annual evaporation capacity change was little from 1971 to 2000 years, but very obvious decline after 2000 years; the gale days was a significant downward trend; sand-dust storms was on a decline trend. |
