This paper uses Data fusion technology to integrate Confucian moral education with Civic Education. Different information sources are detected, and their parameter states are estimated using a weighted estimation algorithm. Principal component analysis is used to linearly transform the original information and calculate the weight values of the main feature vectors. The trust function is established using the D-S combination theory to achieve the fusion of knowledge structures. The results show that the average access rate of the teaching platform constructed based on data fusion reached 89.2% per week, and the average number of platform hits was around 716 per week. It shows that the integration of Confucian moral education ideas has enriched the content of Civic Education for college students and realized the teaching mechanism of double integration and double promotion.
