In this paper, firstly, the index system for evaluating the value of spatial narrative and artistic aesthetics of Han portraits is determined, the judgment matrix is constructed by using the AHP method, and the relative weight coefficients of the indexes are calculated. Then the two-by-two judgment matrix of the indicators is given, the sum-product method is used to solve the judgment matrix, and the relative fuzzy affiliation degree of each evaluation indicator is solved by establishing the fuzzy evaluation subset and the fuzzy evaluation rubric set, and then combined with the weight value, a comprehensive calculation is carried out to solve the problem, to seek to take the spatial narrative of the Han portraits as well as the artistic and aesthetic educational value of the embodied level. On this basis, the spatial narrative of Han portraits is divided into evaluation levels, and the artistic aesthetic perception and aesthetic education function scores of the three Han portrait exhibition sites, H1, H2, and H3, are compared horizontally. The results show that the evaluation levels of external conditions, narrative means, narrative content, and narrative soft environment indicators of spatial narrative are 83.9, 69.9, 79.9, and 78.4 respectively, all of which are more than 70. The aesthetic perception levels of the three Han portrait exhibition sites of H1, H2, and H3 in Q are between (50, 90), and the levels of aesthetic and educational function indicators are between (85, 92). This study creates conditions for the better development of Han portraits, and to a certain extent, it also provides a reference for the development of spatial narrative and artistic aesthetic education of other similar Han portraits.
