为了新能源开发利用，掌握区域性风能资源变化特征，采用朝阳气象站1953—2014年气候资料，运用气候分析诊断技术，研究大凌河朝阳县城区段近62年风速变化趋势。结果表明，年、季节平均风速明显减小。其中，年平均风速线性减小0.7 m/s，春、夏、秋、冬4季分别减小1.2、0.2、0.6、0.8 m/s。有效风速（3～25 m/s）小时数每年减少约20 h。风速减小对风能开发不利，但2006—2014年风速有所回升，接近历史平均水平。研究结果可为新能源开发、风电场设计提供参考。

In order to development and utilization of new energy sources, master regional wind energy resources change characteristics, this paper takes Chaoyang weather station 1953—2014 years climate data, the trend of the wind speed in the past 62 years of Dalinghe River section in Chaoyang County by us-ing climate analysis and diagnosis tech-nology was studied.The results show that the annual and seasonal average wind speed decreased significantly.Among them, the annual average wind speed de-creased linearly with 0.7 m/s, four sea-sons decreased 1.2 、0.2、0.6、0.8 m/s,re-spectively. The number of hours of ef-fective wind speed (3~25 m/s) reduced about 20 hours per year. The decrease of wind speed is unfavorable to the devel-opment of wind energy, but the wind speed picked up from 2006 to 2014, close to the historical average. The re-search results can provide reference for the development of new energy and de-signing of wind farm.
