| 摘 要： | 利用青海省海东市互助县40a(1974-2013年)气温数据,采用线性倾向估计、相关分析、MannKendall检验法等方法,对互助县40a气温的年、季和月变化趋势进行了分析。结果表明:40a来互助县年平均气温呈显著的上升趋势,40a间年平均气温共增加了1.9℃,冬季升温最为显著。最高气温的增温率小于最低气温的增温率。年平均气温、最高气温、最低气温分别在1999年、1990年、1996年附近发生了暖突变。

| Abstract: | Using the Huzhu County Haidong City Qinghai Province 40a temperature data （ 1974 - 2013 ） , using the linear trend estimation, correlation analysis, Mann Kendall test methods, year, quarter and month change trend of temperature in 40a Huzhu County are analyzed. The results showed that： 40 years of Huzhu County annum mean temperature was significantly increased,40a annual average temperature increased from 1.9 ℃ ,winter heating is the most significant. The highest temperature increasing rate is less than the minimum temperature increasing rate. Annual average temperature, highest temperature, lowest temperature in 1999,1990,1996 took place warm mutations. |
