The current rapid development of social economy has had a great impact on the ecological environment of different regions, and this impact has brought more inconvenience to people's daily life. On the other hand, people's requirements for the ecological environment and environmental quality of the area they are living in are rapidly increasing as they continue to improve their material living conditions through the continuous progress of various technologies. This situation has prompted some organizations to pay attention to the development of some things that can purify the urban ecological environment, such as gardens. The various types of garden landscapes in cities can not only purify and protect the ecological environment in their areas, but also significantly improve the quality of life of residents in their areas, better improve the spiritual status of residents, and play an important role in the development of social economy. This role has made the concept of landscape tourism more and more popular, and even a considerable number of people began to seek to visit various excellent gardens. At present, garden tourism is still a comprehensive activity to appreciate various green landscapes and human environments, and also depends on the development of tourism. However, with the rapid increase of people's demand for garden tourism and the requirements for the quality of gardens in the process of tourism, garden tourism has gradually evolved into a relatively complete tourism service system. Through in-depth research on the current concept of green environmental protection, combined with the existing Analytic Hierarchy Process (AHP) to explore the development trend and direction of the existing landscape tourism industry, this paper successively proposed a green and low-carbon landscape tourism development model, and confirmed through relevant experiments that the performance of this new development model in many aspects has increased by about 47.8% compared with the existing development model.
