摘　　要：利用共和盆地多座气象站、测风塔实测数据,运用统计学方法计算、分析了该地区年内风速、风向及风切变变化规律,并结合大气环流、海陆热力差、狭管效应及坡度影响,分析了该地区风能形成机理,结果表明:受季节气候变化、大气环流和海陆热力差影响,盆地风速春季大、秋季小;盆地冬季盛行偏西风、夏季盛行偏南风;受狭管效应和地形影响,盆地中上部相对谷深大,风速大,下部谷深比小,风速小,而且从西北至东南有递减趋,出喇叭口后风速逐渐减弱;该风速成因研究可为后续共和风电基地开发提供支撑。Based on the measured data of several meteorological stations and anemometers in the Gonghe Basin,the annual variation of wind direction,wind speed and wind shear in the region is calculated and analyzed using statistical methods,and the formation mechanism of wind energy in the region is analyzed in combination with the influence of atmospheric circulation,land sea thermal difference,funneling and slope effect.The results show that due to the influence of seasonal climate change,atmospheric circulation and land sea thermal difference,the wind speed in the basin is large in spring and small in autumn.Westerly winds prevail in winter and southerly winds prevail in summer.Affected by the funneling effect and topography,the middle and upper parts of the basin have a large relative valley depth,large wind speed;the lower part of the basin has a small valley depth ratio and a small wind speed,and the wind decreases from northwest to southeast,and the wind speed gradually weakens after coming out of the horn mouth.The wind speed formation study can provide support for the subsequent development of the Gonghe Wind Power Base.
