論文概要: This study focuses on stormwater management issues in China under the Sponge City Initiative, investigating public attitudes and willingness to pay for the initiative, and quantitatively assessing the environmental benefits of sponge city stormwater management infrastructure from an economic perspective. Finally, it proposes new scenarios for the utilization of rainwater resources, contributing practical strategies and suggestions for the development of sponge cities and the sustainability of urban stormwater management.
Chapter 1 introduces the research, highlighting challenges and objectives in China's stormwater management.
Chapter 2 summarizes the environmental benefits of stormwater management infrastructure, surveys public attitudes, and highlights the research's importance.
Chapter 3 introduces the main research methods.
Chapter 4 aims to investigate public understanding of stormwater management, assess the public's perceived value of environmental service benefits provided by sponge city infrastructure, identify the priorities of environmental service benefits, and explore the feasibility of different financing models for stormwater management strategies.
Chapter 5 quantitatively assesses the economic value of improving water quality, flood prevention, mitigating urban heat island effects, rainwater reuse, and landscape recreation through discrete choice models. It clarifies the public's preferences for the benefits of rainwater reuse and reveals the potential of rainwater fees as a funding source for the sponge city stormwater management initiative.
Chapter 6 establishes a new framework for rainwater reuse, using an evolutionary game model to create a dynamic system between environmental and municipal enterprises. It analyzes evolutionary paths and influencing factors to provide valuable insights for promoting effective rainwater reuse.
Chapter 7 summarizes the findings.
