Abstract:	Based on the data of livestock and poultry breeding in the cities of Henan Province from 2001 to 2023, on the basis of data preprocessing, the attribution model of spatial and temporal distribution characteristics of livestock and poultry breeding in Henan Province is constructed, including five submodels, i.e., time trend decomposition model, mutation point detection model, spatial measurement model, spatial clustering model and spatial and temporal difference analysis model. The long-term development trend and periodic variation law of livestock and poultry breeding, the concentrated mutation period of livestock and poultry breeding scale, and the spatial distribution pattern of livestock and poultry breeding in Henan Province are analyzed in detail. Finally, sensitivity analysis of the model is carried out by using the single factor perturbation method. It is found that the coefficient estimation points of each variable in the four scenarios are concentrated in a narrow range, and the confidence interval also shows a high degree of overlap, which proves the stability of the model.
