Abstract
Using the temperature observation data of Qingzhou City during 1961-2010,the change characteristics of annual,season, monthly average temperature and average maximum, minimum temperature in the past 50 years were analyzed by linear regression and M-K mutation test.The results showed that the average temperature of Qingzhou City was increasing from 1961 to 2010, and the climate change tendency was 0.35 ℃/10 a, and the average annual temperature rise of about 1.8 ℃ in recent 50 years.The average temperature of the four seasons was increasing trend, in which the winter temperature warming trend was most obvious, the temperature increase rate was winter, spring, autumn and summer.The mutation year of the annual average temperature was 1989.In the past 50 years, the average maximum temperature in Qingzhou City had been the highest value in the 1960s, the 1970s was the lowest value,and the temperature had gradually recovered since the 1970s, reaching the highest value in the 1990s.The average minimum temperature in the 1960s was the coldest period, since the 1970s, the temperature had risen rapidly, reaching the highest level in the 1990s.关键词
