The invention discloses a wind measurement network optimized site selection and layout method. The method mainly comprises that distribution situation and coverage range of wind measurement towers in a current wind measurement network are analyzed; monitoring points are additionally arranged in areas without coverage of the current wind measurement network according to analysis results; the additionally arranged monitoring points are fine-adjusted according to the position of a wind power plant corresponding to the current wind measurement network; current wind measurement network verification is adopted to verify fine-adjustment results, and when the fine-adjustment results meet the preset parameters, optimization of the current wind measurement network is completed; when the fine-adjustment results do not meet the preset parameters, the process returns and the current network is optimized continuously; the parameters are preset, including coverage range and coverage wind direction of the current wind measurement network, and distance between the wind measurement towers. According to the wind measurement network optimized site selection and layout method, defects in the prior art that anti-interference capability is low, application range is small and operation difficulty is high can be overcome so that advantages of being high in anti-interference capability, large in application range and low in operation difficulty is realized.
