The parameters of wind energy resources at 10 meters above the ground are calculated based on the data from 27 meteorological stations in the north piedmont economic zone of the Tianshan Mountains during 1970—2009. The quantity of the resources is estimated and the area suit for wind farm is chosen by using GIS software with the standard for division of resources and the method of Kriging interpolation. The feature and possibility to exploit the resources at 70 meters above the ground in the area suit for wind farm are analyzed. The area suit for wind farm at 10 meters above the ground is about 12 283 km2 and the exploitable capacity in theory and practice are 11.08×104 MW and 1.9×103 MW respectively. The resources mainly locate in the northeast， northwest， southeast central， and northwest central of the boundary. The resources are most abundant in the period as spring turns to summer， and mainly concentrate in the northwest direction.
