Abstract: Sichuan is a large agricultural province with eight essential agricultural-culture heritage sites of China. This paper first analyzes the development situation and difficulties of China's essential agricultural-culture heritage tourism in Sichuan, and then establishes an evaluation system of agricultural-culture heritage tourism resources to quantitatively analyze the tourism value of the eight agricultural-culture heritages for the purpose of promoting the development of China's essential agricultural-culture heritage tourism in Sichuan, and realizing the sustainable development, utilization and protection of agricultural-culture heritage. The average score of agricultural-culture heritage tourism resources in Sichuan is 7.89, while five heritages do not reach the average value, but the gap between the scores of various places is not big. The popularity, development and utilization of most agricultural-culture heritages, and the formation and development of related industries have not yet formed a good interaction with tourism. Based on the above analysis, this paper proposes four models to promote the development of China's essential agricultural-culture heritage tourism in Sichuan: a model of real-world experience, a model of heritage pavilion, a model of research-study tourism, and a model of joint development.
