Objective  With the rapid development of urbanization, people in cities have been exposed to air pollution and social pressure for a long time, and since the outbreak of the COVID-19 epidemic in 2020, people become increasingly yearning for nature. Under the background of rural revitalization, beautiful countryside has become a popular destination for tourists in recent years. As an important part of rural tourism, rural boutique lines are of great significance to enhance tourists' intention to revisit the countryside, improve villagers' life, and narrow the development gap between urban and rural areas.

Methods  Landscape perception emphasizes the mutual influence between tourists' perception, recognition and preference of a tourism environment, which can directly reflect the effect of the tourism environment during the planning and construction thereof, and accordingly affect the tourists' intention to revisit the tourism environment. Although scholars have slightly different views on the process of landscape perception, it is generally believed that landscape perception contains three important components, which are summarized in this research as external environmental stimulus, emotional state and behavioral response. In combination with the theory of landscape perception and the landscape structure and functional characteristics of rural boutique lines, this research takes the external environmental stimulus, emotional state and behavioral response just mentioned as the research framework for analyzing tourists' intention to revisit rural boutique lines. On this basis, the research constructs a structural equation model to present tourists' intention to revisit rural boutique lines. Three representative rural boutique lines in Zhejiang Province are selected as the research object for demonstration.

Results  Research results are as follows. 1) Tourists' landscape perception is affected by the degree of accessibility, and can influence tourists' satisfaction and place identification. 2) Landscape perception includes four dimensions: ecological environment, cultural history, leisure and recreation, and production economy, all of which have significant influence on tourist satisfaction and place identification, among which cultural history has the greatest influence, indicating that landscape culture is the core factor driving tourists to form local emotion. 3) Tourists' positive emotion towards a rural environment positively promotes their loyalty to the destination, which in turn affects their landscape perception. This means that the stronger the behavioral response of tourists' intention to revisit a rural environment, the higher the perceived value of the rural environment in such aspects as ecological environment, cultural history, or leisure and recreation. 4) From the perspective of the interactive characteristics of tourists' emotional state and behavioral intention, tourists prefer authentic and local rural landscape. Diversified history and culture, recreational activities and rural lifestyle can be generated on the basis of rural landscape. Through sensory stimulation such as touch, smell and vision, tourists can create an interactive atmosphere of scene integration, and realize the interactive relationship between static rural landscape and dynamic behavioral response. In addition, the warm and beautiful social relationship generated by the interpersonal interaction between tourists and villagers is also one of the essential factors for the emotional integration of rural boutique lines, which can improve tourists' loyalty to and enhance their intention to revisit rural boutique lines.

Conclusion  Based on the above model, this research puts forward the following practical suggestions for the planning and construction of future rural boutique lines. 1) In the planning and design of rural boutique lines, firstly, it is necessary to pay attention to the mining of existing resources, and consider the linkage between existing resources and surrounding resources to drive the regional resource flow. Combined with the statistical analysis results of the scale adopted in this paper, it can be concluded that tourists prefer rural boutique lines with the resources and characteristics of humanity, history, agriculture and leisure. Therefore, when planning and designing rural boutique lines, designers should make full use of the existing resource advantages to show the internal qualities of rural boutique lines such as being native, humanistic and economic and other internal qualities. Meanwhile, designers should also well satisfy tourists' motivation and expectation for recreation, thus improving their satisfaction, place identity and loyalty to rural boutique lines, and enhancing their intention to revisit rural boutique lines. 2) In the planning of activity experience of rural boutique lines, attention should be paid to the interaction between people and landscape, because interaction serves as the bond that maintains the emotional relationship between landscape and people, which can strengthen tourists' satisfaction and placing identity, and accordingly contribute to the sustainable development of rural boutique lines. The development of activity experience should comply with objective laws such as season changing, and be combined with the multi-sensory stimulation of human body to create special activities such as flower appreciation and camping in spring, summer heat avoidance and stargazing in summer, harvesting in autumn, and physical fitness in winter, so as to associate the time dimension with tourists' landscape perception, and strengthen the interaction between landscape and people. 3) In the promotion and publicity of rural boutique lines, it is supposed to, based on the research data of this research, highlight landscape perception types such as human history and ecological environment that tourists prefer, so as to enhance the attraction of rural boutique lines to potential tourists.
