In order to avoid the homogenization of urban road landscape design in China and explore the cultural connotations in urban road landscape design, based on the study of cases of integrating regional culture into urban road landscape design at home and abroad, this paper analyzes the historical context of Qujialing's regional culture and proposes the application of agricultural valley culture in urban road landscape design. Based on the functional positioning and current conditions of the south extension of Qujialing Nonggu Avenue, landscape design will incorporate elements of "agriculture, farming tools, and farmers" into the road's starting and ending points, as well as the three sections of the road landscape belt along the route. The research shows that the application of agricultural valley cultural elements in urban roads integrates pastoral scenery into urban landscapes, promotes the inheritance of agricultural civilization regional culture and the development of agricultural ecological tourism economy, and provides reference for similar road landscape design.
