Green space introduction: Planting in Songnan Park is in the form of dense planting. The mixed dense forest is mainly planted with camphor, cedar, filial bamboo, red-leaf plum, wintersweet, and camellia. It is a plant community with a multi-level structure. Large trees, small trees, large shrubs, small shrubs, and ground cover each form different levels according to their own ecological requirements and interdependent conditions, so the seasonal changes are relatively rich. The vertical layered composition of the forest edge portion for tourists to appreciate should be very prominent, but it should not be completely filled up, so as to affect visitors' enjoyment of the unique deep and profound beauty of the forest.
