The invention belongs to the field of wind power plant development, and particularly relates to a wind resource parameter determination method and device, and the method comprises the steps: carrying out the classification of all fans related to a wind power plant based on the attribute information of the wind power plant, and obtaining at least two fan types; determining an average power curve, a fan frequency and a first average wind speed of all fans under the same fan category based on SCADA data of all fans associated with the wind power plant; on the basis of the average power curve, the fan wind frequency and the first average wind speed, the preprocessing wind speed of each fan in the wind speed interval with the optimal wind energy utilization coefficient is determined; determining a target fan matched with the anemometer tower from all fans associated with the wind power plant based on the preprocessed wind speed; and determining a cabin wind speed correction coefficient based on the time sequence o
