Growing energy demand, energy security issues are more and more payed attention to. Wind power, one of the most efficient en ergy, can help us address these issues in modern society. Wind energy is secure, clean, rich in resource and inexhaustible. As is a permanent presence of a large number of local resource, wind power can provide us with long-term stable energy supply. Assessment of wind resource and wind farm planning is the early part and priorities of the construction of wind farm. Evaluation and planning plays an important role in the full use of wi nd resource and the enhancement of the combined effectiveness of wind farm. In this paper, we study the Dadingshan wind farm as the research object,
