The invention provides a method and a system for analyzing a topographic gradient and a wind speed acceleration effect under a predominant wind direction. The method comprises the following steps: determining the topographic gradient under the predominant wind direction based on obtained hilly land shape parameters within a predominant direction angle range; based on fluid simulation analysis, a wind speed acceleration ratio corresponding to the hilly land shape is obtained; and constructing a relation curve of the topographic gradient and the wind speed acceleration ratio under the prevailing wind direction based on the topographic gradient and the wind speed acceleration ratio under the prevailing wind direction. According to the method provided by the invention, the relation curve of the topographic gradient and the wind speed acceleration ratio under the predominant wind direction is constructed through the topographic gradient under the predominant wind direction determined by the hilly land shape parame
