In the layout of the road network,

In the layout of the road network, in addition to clarifying the hierarchical structure of the road network, it is also necessary to enhance the identifiability between park roads. The road network layout of the same scenic spot or the same level should have continuity. Continuity can be generated not only by the same width, but also by the garden road pavement. That is to say, the road network in the same landscape node or functional area adopts the same pavement form or the same material to indicate the consistency of road network in nature and function. When the road pavement changes, it means the change of the nature and function of the road network, and tourists experience the change of the space immediately. Considering the diversity and variability of road network pavement, we can adopt the same stone laying method with different materials, or the same material with different paving methods, as well as the same material with different colors and textures to ensure the same and continuity of the garden road. Different landscape nodes or different levels of road network layout should be different. For example, in the main garden road, concrete, asphalt or cement pouring integral pavement can be used, while in the secondary Garden Road, block stone pavement can be used. For the walking path, its pavement materials can be more diversified and interesting, such as gravel, pebble, straw brick and other special materials. So that the garden road has obvious identifiability
