Abstract: On the basis of 1971-1980 wind speed data from 332 weather stations (158 of them are automatic recorders), calculations are made on the number of hours of the effective wind speed (3.5-20.4ms-1), the annual and monthly amount of wind energy, and the change regularities of the wind speed and the wind energy. Distribution maps are drawn for the annual effective wind energy and effective wind speed frequncy. according to these maps the regionalization of wind energy and its variation with height are proposed.Using the practical data about the wind energy, the relation between the wind energy and the energy output through a wind machine is explored, and there upon the value of the utilization of the wind energy resource is found out for irrigation and electricity generation in given areas.According to the conditions of the wind energy resource, environment, topography and underground water level, proposals are made on the proper choice of design wind speed to set up a network of wind machines to provide energy for local use. The prospects are found encouraging.Since the results presented have been verified with satisfaction, the paper may serve as a better reference for authories concerned to plan their work.
