The woody plant diversity and landscape pattern of fine-resolution urban forest along a distance gradient from points of interest in Qingdao

Points of interest (POIs) are closely related to urbanization and human mobilities, and would consequently affect the spatial distribution of urban forest and its species diversity. However, the issue on what the relationships between POIs and urbanization, and how do POIs affect urban forest was ra...
