Abstract:

Urban biodiversity is now recognized as playing a critical role in supporting global biodiversity. However, it is important to note that biodiversity is a systematic and holistic concept and prior studies have not generally focused on cross-border or multi-scale management problems. On one hand, the ecosystems of cities are interconnected with adjacent cities by natural landscapes, so they are like mosaics instead of being isolated. Urban biodiversity research demands the consideration of the continuity within an ecosystem. On the other hand, both active protection and passive restoration strategies for urban biodiversity should not only be developed by researchers or municipal government agencies, but more importantly, they should consider the real ecosystem management problems faced by multi-scale departments in order to build a practicable Pressure-State-Response (PSR) model. The solutions for these issues should be included in the analysis to form a complete and more effective urban biodiversity strategy. The study in this paper offers an answer to whether different scales of cities or districts should adopt the same biodiversity strategy; and therefore, the decision depends on whether the places are of the same importance to the global or regional ecosystem, or whether the ecological elements are connected to the adjacent cities/districts and the problems that multiple stakeholders care about.
