ObjectiveBeijing Urban Master Plan (2016-2035) puts forward the goal of "leave blank space and increase green space" and let forest enter the city. Urban forest has multiple functions and is an important part of urban ecosystems. The purpose of this study is to explore the functional types of urban forest and the strategies for habitat-based urban forest construction, with a view to realize the expansion of urban forest functions in a specific city context, making urban forest as a green space for solving different urban problems, and promoting the sustainable development of urban ecosystems.

MethodIn this context, based on the study of a large number of literatures, this study discusses the function types of urban forest based on the three main factors: the dominant function, the type of surrounding land, and the positioning of the master plan, and research on habitat-based urban forest construction strategies.

ResultThree primary categories of ecological type, life type and production type were proposed, including seven secondary classifications of habitat type, environmental regulation type, landscape recreation type, popular science education type, health service type, facility protection type and economic production type. Urbanization has led to a sharp decline in urban biodiversity, paying attention to and protecting biodiversity has become an important part of urban development. This study selected habitat-based urban forest with the main goal of improving biodiversity as the research object, proposed the construction strategy of target species selection, woodland habitat and water habitat, and took the Hengjiezi urban forest as an example to practice the construction strategies.

ConclusionThe discussion of urban forest function types can provide target guidance for urban forest construction. The research on construction strategy of habitat type urban forest can provide reference for future urban forest construction.
