The invention belongs to the technical field of material science, and particularly relates to a construction method of a material performance prediction model, and a material performance prediction method and system. The method comprises the following steps: collecting a marked sample set; constructing an unmarked sample space; constructing a plurality of training sets based on the marked sample set; training a machine learning model by using the plurality of training sets to obtain a plurality of prediction models; a plurality of prediction models are adopted to predict samples in the unmarked sample space, a plurality of prediction values are obtained for each unmarked sample, and samples needing to be marked in the next round are selected according to the uncertainty of the prediction values; marking the selected samples, and adding the marked samples into the marked sample set; removing unmarked sample spaces from the selected samples; and repeating the operation until the prediction performance of the ob
