Using data from many surface weather observing stations and regional weather stations, the resources of wind energy are analyzed. The results indicate that different place of weather data has a tremendous influence on the evaluation of wind energy potentials for economic development in the eastern Jining. The conventional surface weather observations tend to underestimate wind energy resources in mountainous areas. However, the data from regional weather stations in mountainous areas especially near the summit (i.e. the site of automatic weather stations) track the mountainous resources of wind energy fairly well. According to data from the latter weather stations, it illustrates that Jining mountainous areas can be used to gather lots of wind energy and in the spring it is abundant in wind energy. And still harnessing the power of wind to make electricity for irrigation can alleviate spring drought in those areas.
