| 摘 要： | 分析了达坂城气象站1961--2008年风的气候特征及48a来风速最小年2008年的风能参数。结果表明：达坂城一日之中17—18时风速最大，07-08时最小；一年之中4—5月风速最大，9—10月最小；风速变化分4个阶段，其中1986--2008年风速呈减小趋势，特别是2000年以来风速明显偏小，2008年出现了近48a来的最低值；一年之中以4-9月风速减小最为显著。2008年的风能参数达到了“风能较丰富”的指标，近期为风能资源偏少时期，特别是夏半年风能偏弱。

| Abstract: | The climatic characteristics of wind during 1961-2008 and the parameters of wind power of 2008 with the minimum wind speed were analyzed on the basis of observations from Dabancheng weather station. The results were as follows： the daily maximum wind speed of the Dabancheng region appeared at 17：00-18：00, the minimum at 7：00-8：00, the annual maximum wind speed appeared in Apr.-May, and the minimum in Sep.-Dec. The changes of the wind speed in recent 48a possessed four phases, in which the wind speed was decreasing during 1986--2008, particularly evident since 2000, and the lowest value appeared in 2008. the most significant decrease was from Apr. to Sept. of a year. Parameters of the wind energy in 2008 reached only an indicator of ＂wind energy rather rich＂. Recently, the wind energy resource of Dabancheng is in the period of negative anomaly, especially in summer half year. |
