The invention relates to a modeling method of a boiler combustion optimization. The prior method can not solve the problem of boiler combustion optimization. In the invention, segmentation is carried out according to the active parameter load of combustion of a boiler, the load working conditions of similar combustion situations are segmented into one segment, the load working conditions with large differences are separately modeled, and a modeling method which is suitable for small samples and has high generalization ability is adopted for the low load working conditions with less data or extremely low load working conditions; selections which are distributed evenly and equal in quality on a topological structure are carried out for model data before modeling, a proper pretreatment is carried out to guarantee the predictive ability and the generalization ability of models, and finally the models corresponding to the load segments are selected to be optimized according to the load segment where a real load is
