Abstract: Scientific and reasonable urban forest spatial planning is the core of realizing healthy development of a city. Taking Chengdu Direct Management Area under Tianfu New Area, the first proposed site for park city construction, as an example, this research focuses on existing questions, such as high-degree urban forest fragmentation and land use overlapping. Based on the MSPA method, it extracts the spatial elements of the urban forest, and proposes to construct a networked forest spatial layout that is an organic combination of forest sources, forest nodes and forest corridors. It further explores the space landing methods based on the third national land survey data, and creatively proposes to protect forest sources, supplement forest nodes within the urban development boundary, and increase forest nodes outside the urban development boundary, as well as construction implementation strategies such as structured forest corridors. The research provides references for urban forest spatial planning and implementation from the perspective of healthy cities at home and abroad.
