Abstract:According to the data of temperature，precipitation，the beginning of frost，the end of frost，frost－free period，≥0℃and　≥10℃accumulated temperature from Shuozhou Meteorological Bureau in Shanxi Province during the period of 1957－2009，the climate change in Shuozhou city was analyzed．The results showed that the precipitation in Shuozhou decreased，but the temperature increased．Along with annual mean temperature’s increase and precipitation’s remarkable reduction during 1998－2009，the date for the　beginning of frost was obviously postponed;and the date for the end of frost presented stable and early trend．The frost－free time presented prolonged tendency．The accumulated temperature of≥0℃and≥10℃presented increase trend．These changes will affect　layout and structure of the local agricultural production．Key words:climatic change;precipitation;temperature;the date of beginning and end of frost;frost－free eriod;accumulated temperature;Shuozhou

Based on meteorological observations such as pan evaporation, temperature, sunshine hours,wind speed, humidity during 1956-2005 in Shuozhou ofShanxiProvince, the annua,l monthly and seasonalvariation ofevaporation in Shuozhouwas analyzed in detai,l and the influence factors of evaporation were also discussed. Results show that the evaporation presented an obvious downward trend in recent50 years in Shouzhou, especially in spring and summer, and decreasing trendwasmost remarkable inMay; Therewas obviously positive correlation between evaporation and sunshine hours, mean wind speed, mean temperature daily range, but negative correlation between evaporation and relative humidity, vapor pressure, which indicated that sunshine hours, mean wind speed, mean temperature daily range, relative humidity and vaporpressureweremain factors resulted in evaporation decrease in Shouzhou of Shanxi Province.
