Abstract: In order to optimize and promote agricultural tourism information services and platform construction, a mixed user interest model based on short-term user interest and long-term user interest was established. Based on this, the core demand analysis and system module design analysis of the agricultural tourism system were carried out. Finally, the platform performance and user satisfaction of the mobile system were investigated. The results showed that user click-through rate and data visits were basically positively correlated, and the trend of the curve was basically the same. The mobile recommendation system can promptly feedback the user's operational needs and return the results. The satisfaction of tourists and farmers with the system has increased from 56% to 78%. At the same time, the satisfaction expectations of agricultural products and agricultural attractions recommendations have also increased from 77% and 68% to 96% and 95%, respectively.
