摘　　要：运用新一代中尺度模式WRF对酒泉部分地区进行了风场的数值模拟。结果表明,WRF模式对复杂地形条件下的风场具有较好的模拟能力,也能较好地模拟出地形对风速的影响。在此基础上,结合GIS技术在空间信息处理方面的优势,综合考虑各种地理要素的影响,对酒泉地区风能资源进行精细化研究,分析风能资源开发的优势度,发现(1)研究区域具有非常丰富的风能资源,较丰富区以上地区的面积将近达到研究区域的一半;(2)丰富风能资源区与该地区的地形有很好的对应关系,主要处于有地形狭口效应的区域;(3)最有利于风能资源开发的区域在玉门镇以南至昌马,这一片区域的地形平坦,风能资源丰富,又是戈壁,非常适合建设大型风力发电场。这些显示了酒泉地区风能资源开发的优势度分布,能为风电场的选址提供参考。Using the new generation mesoscale numerical weather prediction system WRF model,the wind field in the partial region of Jiuquan is simulated.The results show that the WRF model performs well in the simulated wind field with the complex terrain,such as the impact of terrain on wind speed.Based on the simulation and comprehensive consideration of the geographical influence,as well as Geographical Information System（GIS） technique,the wind energy resource in Jiuquan region is well researched and its advantage degree is analyzed.It is found that：（1）There is very abundant wind energy resource in this study area,in which the area with higher development advantage degree count for nearly a half.（2）The abundant wind resource region is well a correspondence to the topography,mainly located in the area with a narrow-mouth effect.（3）The most favorable region for the wind resource exploitation is located between Yumen and Changma,this area is very suitable for the large wind field building because of its flat terrain,abundant wind resource and Gobi landuse.These outcomes give an advantage degree distribution for the wind resource in Jiuquan region and provide a reference for the selected wind field.
