Abstract: In this paper, numerical simulation with GIS spatial analysis method and observation with field investigation method are used to find the distribution of mountain area wind energy resources of Jiangxi Province and estimate its reserves quantitatively. In addition, the measured data of two anemometer towers of mountain wind field are used to analyze the wind resources characteristics of mountain area in detail. The results show that the wind resources in mountain area of Jiangxi Province present linear distribution along the mountain ridge or in point distribution on isolated mountain peak, with a technical exploitation amount of wind resources being about 111×104 kW, the technical exploitation area about 136 km2, and the installed capacity about 148×104 kW. Wind speed and wind power density in mountain area are higher, and increase slightly with the increase of the height, and the wind shear indexes are very small, being 0.017 and 0.098 respectively. The daily variations of wind speed and wind power density in mountain area appear obvious U-shaped distribution, that is, the wind speed and wind power density are the smallest around noon, and from early in the morning to morning, the values are large, the largest and the smallest values differ 1-2 m/s. In the mountain wind field, there are two dominant wind directions which are approximately to the opposite, the two dominant wind directions respectively focus on the NW-N section and SSW-SSE section, being helpful to the allocation of wind turbine.
