Wind energy resource is an important renewable and clean energy, and wind energy resource evaluation is an important link and prerequisite for wind farm construction. Based on the data of two wind measuring towers in Wunao Mountain wind farm in Tonghai, Yunnan Province, the intermonthly and diurnal variations of wind speed, wind power density, frequency distribution of wind speed and wind energy, wind direction and wind rose chart, wind shear index, turbulence intensity and wind condition parameters of Wunao Mountain wind farm at different levels were analyzed. The results show that the wind speed and power density of Wunao Mountain wind farm are larger from January to April, and smaller from July to November, with obvious two-seasonal winds variation characteristics. The frequency distribution of effective wind speed at 70 m height in Wunao Mountain wind farm is concentrated between 3.5 m/s and 13.4 m/s, and the effective wind speed time is concentrated between 7750 and 7990 h. The wind energy density direction is concentrated between W and SSW, which is conducive to reducing the fan yaw operation. The turbulence intensity of Wunao Mountain wind farm is medium. The wind power density of the two wind measurement towers at 70 m height is 265 W/m2 and 160 W/m2 respectively, belonging to the rich and sub-rich areas of wind energy resources. Wunao Mountain wind power farm has certain engineering development value in the altitude range above 2250 m. The frequency of thunderstorms in Wunao Mountain wind farm is high, so attention should be paid to preventing the impact of lightning disasters. Through the wind energy resource evaluation of Wunao Mountain wind farm, the particularity and diversity of the site selection and wind energy resource evaluation of mountain wind power farm in Yunnan province under complex terrain conditions are confirmed, and it has a good demonstration role for the evaluation of mountain wind energy resources. %K 风电场， %K 测风塔， %K 风功率， %K 风能资源， %K 风况参数， %K 高原山地
