Park road network is a combination of traffic function, landscape function and regional function. When the park road network pays too much attention to the traffic and the layout is mainly convenient and fast, at this moment, the park road can't organize all the park landscape nodes comprehensively and richly, and the tourist attraction will be greatly reduced. However, when the park road network pays too much attention to the landscape and pays attention to the artistry of planning, the form of the park road is particularly zigzag, and the guiding role of the road network is also difficult to be effective, and it is easy to promote the behavior of tourists taking shortcuts, And it does not meet the regional requirements of the road network, which will also cause damage to the ecological environment. Therefore, in the process of planning and design, we must pay attention to the balance among road network traffic, landscape and region. The road network layout should seek the balance between the traffic function and the landscape function on the premise of meeting the function diversification. Of course, when the landscape along one garden road is colorful and attractive, this choice is another. Therefore, when planning the road network layout, for places with large vertical height difference, besides the path conforming to the contour line, it is also necessary to consider the more convenient contact ways such as overhead trestle road and echelon Road, so as to facilitate the tourists to quickly transition from one scenic spot to another. And the most suitable path between the transverse direction can be solved by the layout method of "preset shortcut line". That is to say, in the process of park road network layout, mark "shortcut lines" between landscape nodes in advance, and then the road network layout generally reflects these "shortcut lines", which can reduce the continuity and difference settings to achieve the unity and change in park road layout
