This paper selects rural tourism development indicators and cultural industry development indicators, respectively, and constructs the evaluation system of comprehensive development level of rural tourism development and cultural industry. The dynamic coupling evolution algorithm is proposed, algorithm improvement is carried out, and the improved coupling model is used to substitute rural tourism development and cultural industry development to analyze the dynamic coordination evolution of the two. Use hierarchical analysis to calculate the weights of the indicator system. Combined with the comprehensive development level of rural tourism and the comprehensive development level of the cultural industry, the coupling and coordination level of the two are measured, and suggestions for the integrated development of rural culture and tourism are put forward. By 2020, the coupling coordination degree of the cultural industry and rural tourism industry in L city will develop to 0.734, and both the cultural industry and rural tourism industry will reach the intermediate level of coordination, but the development of the tourism industry is relatively lagging, and the comprehensive development level of the cultural industry will be 0.695, and the comprehensive development level of tourism industry will be 0.562.
