Abstract: Based on reorganized climate data from 1971 to 2000, the situation of the wind energy resources in Mao County was preliminary analyzed in this paper.The result shows that:(1) As the result of a specific geographical terrain conditions, the wind energy resource of Mao County is one of the most abundance areas in Sichuan and Hengduan Mountain area.Although the annual average wind energy density is only 27.44 W/m² (calculated by the observations of Meteorological Bureau of Mao County), the local wind speed is large throughout the year with a stable wind direction and winds usually starts at fixed time.Therefore the local wind energy should have a great value of exploitation and utilization. (2) The characteristics of wind in Mao County are as follows:There are windy days in all seasons.Wind is strong in winter and spring (from December to May in the next year, the average wind speed is around 4.1m/s), moderate in autumn (in October and November, the average wind speed is as much as 3.6m/s), and quite gentle in summer (from June to September, the average wind speed is as much as 4.1m/s).In March, the wind is the strongest, the speed could be 4.6m/s, and in September is the softest, only have a speed of 3.2 m/s.According to the average wind speed during 2 minutes observed 3 times a day by Meteorological Bureau of Mao County, although it is mostly calm wind in the morning, the average wind speed during many years is still as much as 3.8 m/s, the strongest in the province. (3) The calculation based on the observations of meteorological station in Mao County shows that the county's wind energy resources seem relatively poor, but due to complex terrain of the county, the observation data by the Meteorological Bureau of Mao County cannot be fully representative of the particular wind energy distribution of the whole County.It is necessary to build wind observation stations in the areas with bigger wind speed so as to accumulate information of actual situation of wind energy, and to provide more scientific and convincing data for the exploitation of wind energy resources in Mao County to benefit the local people.
