The invention provides a method for obtaining distribution of wind resources capable of power generation. The method mainly comprises the following steps: step S10, obtaining historical wind speed data of previous six hours of each wind measuring tower; step S20, at each full hour time point, according to wind speed data correlation of the previous six hours, performing clustering on the wind measuring towers; step S30, assuming that there are n wind measuring towers at a wind power base, calculating a geographical distance Ri between a to-be-calculated point and all the wind measuring towers Ti(i=1,2, ..., N); step S40, finding a smallest wind measuring tower Ti(i=1,2, ..., N) of the Ri; step S50, according to calculation results in the step S20 and the step S40, determining other wind measuring towers in a group which a wind measuring tower Ti belongs to; and step S60, carrying out interpolation on selected wind measuring towers by use of an inverse distance weighting method to obtain wind speed and wind direction estimation values of known points.
