Abstract
Rapid urbanization has led to deterioration issues of the urban living environment, such as excessive land development and utilization, environmental pollution, drastic reduction in the quantity and diversity of green resources. Due to the shortage of green space in the metropolitan area, botanical gardens, parks, and campuses as well as the urban green belts that exist around the roads have become the main leisure place for the people. As a result, the usage rate of green space in the city, which trees are planted in busy areas, is extremely frequent. From the viewpoint of risk assessment, in such spaces, accidents may cause serious consequences. However, urban trees are often faced with harsh challenges due to the habitats, microclimates, and limiting factors are way different from their original and adaptive environment. Besides, urban planning or human factors could cause threats to their health. Moreover, there is lack of scientific data of soil hardening and pest management. Therefore, the purpose of this project is to promote the overall health condition of the urban forest by exploring the urban tree health management, tree living environment assessment, and soil health management. Finally, this project will build a data-sharing platform constructed with the scientific quantified benefits of urban forest indicators that will facilitate public knowledge to quickly understand the economic and health value of urban forests. Our results will be applicable for those policies relating to improvements in the management of urban forests and therefore will be beneficial to the overall health of the urban forest and the safety of the citizens. Biodiversity in cities is capable of reducing the pressure derived from the environmental change. Birds will be used to discuss management of urban biodiversity because birds represent a good indicator of biodiversity.
