The low-altitude economy brings new opportunities for the development of tourism, and the demand for regional cultural tourism to enhance its services and improve tourists’ satisfaction is becoming more and more urgent. Taking the cultural tourism service system in Anhui Province as an example, the study extracts and summarises tourists’ demand indicators based on the Kano model and stakeholder theory and classifies them into four types, namely, anticipatory, basic, undifferentiated, and glamorous demand, through the Better-Worse coefficient. Subsequently, the demand indicators were calculated and second-ordered using demand sensitivity. By analyzing the importance of different types and aspects of needs, the priority of tourists’ needs was determined. Based on the conclusions obtained from the analysis of tourists’ needs, an intelligent service system for cultural tourism in Anhui Province is constructed, and a cultural tourism blueprint and information architecture are designed. The demand analysis points out that the most important aspect of intelligent services for cultural tourism in Anhui Province is to satisfy anticipatory needs while prioritizing basic needs. It is possible to moderately relax or slow down the satisfaction of undifferentiated needs of tourists and put the design focus on the service design of glamour needs.
