The 19th National Congress of the Communist Party of China (CPC) put forward that we should adhere to the priority development of agriculture and countryside, promote the integration and development of one, two, three industries, and vigorously implement the strategy of rural revitalization. This study mainly aims at the unbalanced development of agriculture and tourism, and constructs the evaluation index system of the integration of modern agriculture and rural tourism, and takes Yangjia Town of Mianyang City as an example to carry on the empirical research. This paper further analyzes the problems existing in the process of the integration of modern agriculture and rural tourism in Yangjia Town, Mianyang City, and puts forward some effective countermeasures and measures to solve the corresponding problems, so as to provide a reference for the further development of agricultural tourism integration and the realization of rural revitalization.

Tourism carbon emission is one of the important factors affecting ecological environment. In order to clarify the trend and changing characteristics of tourism carbon emissions, academia has carried out quantitative research on tourism carbon footprint. Based on the theory of carbon footprint, this study analyzes the tourism carbon emissions in Sichuan Province from 2004 to 2018 through three indexes: tourism carbon footprint, carbon carrying capacity and net carbon footprint. The results show that the carbon footprint of tourism in Sichuan Province shows an increasing trend. During the fifteen years, it increases by 20.2 times from 427.59 million tons to 9505.95 million tons. The carbon carrying capacity of tourism is increasing year by year except in 2008. Sichuan Province was in a carbon surplus before 2012. The carbon carrying capacity is greater than the carbon footprint, which is friendly to the ecological environment. After 2012, Sichuan Province is in a state of carbon deficit, and the ecological pressure is increasing, which is not conducive to human survival.
