利用达坂城气象站1981—2010年逐年气温、降水和大风资料，分析了近30年来气温、降水及大风的年、季变化特征，结果表明：年均气温总体呈上升趋势，线性倾向率为0．33℃／10a，年内气温的季节变化存在差异，秋季增温明显，春夏季次之；降水量线性倾向率为9．44mm／10a，气候变湿显著，降水年际变率较大且季节分配不均；Mann—Kendall突变检验表明，气温在1991年发生一次突变，变暖趋势显著，降水在1986年发生由少向多的突变过程；大风日数、平均风速呈现波动下降过程，大风日数线性趋向率为-30．5d／10a，平均风速递减率为-0．76（m／s）／10a，春季大风发生频率最高，为33％，静风频率为10．32％；主导风向以偏西风（WNW）和东南风（SE）为主。

Using the observed temperature, precipitation and strong wind dams from the Da- bancheng Meteorology Station during the period from 1981 to 2010, this paper analyzed the annual and seasonal changes of the metrological factors during the last 30 years. The results show that： During the last 30 years, the temperature had a trend of increasing and the rate was 0. 33 ℃/10a. The change of temperature in a year showed seasonal disparities that it had aobvious trend of increasing in autumn, following by spring and summer. And the increasing rate of precipitation was 9.44mm/10a. The precipitation had obvious variations in inter-annual and the seasonal change of precipitation was distinctive. The Mann-Kendall test shows that： the annual mean temperature exhibited an obvious increase trend in the recent 30 years, and an abrupt temperature change happened in 1991 ;an abrupt change from less to more of annual precipitation occurred in 1986; The strong wind days and average wind speed show a wave decreased during 30 years, the decreasing rate of them were-30.5d/10a,-0.76 （m/s）/10a, The highest frequency of the strong wind happened in spring, the rate was 33%, and Static Wkxd was 10,32%;Dominant wind direction is WNW and SE.
