Abstract: On the basis of the original vegetation, the major work of forest park is plant design, to creat a natural botanical garden atmosphere. According to a survey of Yanqing Gui River Forest Park, the structure and arrangement of plant community were discussed. The plant community of the park was mainly composed of indigenous tree species. The hierarchy of arbor, shrub and grass was clear and the plant species were rich. The park took ecology as a starting point, reflecting the beauty of plant group. Taking some typical plant spaces as example, the relationship between plants and roads and water was studied, providing references for plant arrangement of forest parks in the future.
