The Garden Road, which is laid out according to the terrain, often presents a complicated and chaotic structure. However, as an important element in the park planning and design, the road network also bears the function of direction guidance and tour guidance. The complex and chaotic road network structure not only makes people lose their way easily, but also affects the normal function of the road network. Therefore, in the road network layout of jianghanwan Park, we are committed to overcoming the unreasonable design caused by the road network structure and alleviating its complex and chaotic road network structure. Based on this, the paper puts forward the requirements of clear structure of jianghanwan park road network layout. The so-called clarity is to make the complex road network structure clear and regular by means of clarifying the form differences and functional differences of each grade of the road network, so as to achieve the structural form of "form is scattered but spirit is not scattered", so as to better play the traffic organization function and landscape construction function of the park road network
