摘要
The dilemma of managing the trade-off between immediate human needs and maintaining the ability of the Earth to provide ecosystem services is considered to be one of the greatest challenges of this century. Many management strategies have applied the ecosystem service concept to address this challenge, which incorporates land management, policy, and economic decisions to achieve overall ecosystem health. The intent of this research was to improve such decisions through an increased understanding of the relationship between urban stormwater control measures (SCMs) and freshwater provision, erosion regulation, and flood regulation ecosystem services. Fifty-six land management scenarios with varying densities of targeted SCM application were simulated using the software PCSWMM. The ecosystem services resulting from these land management scenarios were quantified using a set of mathematical indices. Results demonstrate that the application of bioretention cells improved both freshwater provision and erosion regulation services immediately downstream from the implementation site and at the same time increased erosion regulation services at the greater watershed scale.
