《绿色和灰色基础设施系统耦合的好处：基于层次分析法和生命周期成本的证据》
Benefits of coupled green and grey infrastructure systems: Evidence based on analytic hierarchy process and life cycle costing
Green infrastructure complements grey infrastructure to provide effective urban stormwater management. Design of coupled green and grey infrastructure systems need a systems-based analysis considering multiple criterion. This study used analytic hierarchy process (AHP) and life cycle costing (LCC) to evaluate environ- mental and economic benefits of various types of coupled green and grey infrastructure systems. AHP results showed that, based on the local conditions and characteristics, the coupled green and grey scenario with green space, permeable pavement, green roof, and stormwater detention cell performed better than other scenarios in urban residential drainage and flood control. Also for the coupled green and grey scenario, the simulation results showed that no flooding was occurred during the ten-year return period rainfall. Coupled green and grey in- frastructure scenarios can save the life cycle cost up to 94% compared to the traditional grey infrastructure scenario considering the design, construction, operation, and maintenance stages. Approximately 13% of commercial loan interest (1.03 million USD) can be saved for homebuyers. In future, urban designers and de- velopers should consider the optimization of coupled green and gray infrastructures system under multiple criterion for the environment, economy, and safety benefits.

《从生命周期的角度对低影响发展类型的最佳管理实践进行环境和经济评估的进展》
Progress on environmental and economic evaluation of low-impact development type of best management practices through a life cycle perspective
A rapid progress of low-impact development type of best management practices for urban storm water runoff quantity and quality control at a global scale has occurred in the past decade. In-depth research on low-impact development type of best management practices as useful technologies and measures to control stormwater runoff is being conducted worldwide. This paper presents a literature review of the environmental and economic evaluation of low-impact development type of best management practices through life cycle perspective. Research gap and future agenda are also proposed. Results show that life cycle assessment or life cycle cost analysis for low-impact development type of best management practices are widely documented. However, certain challenges still exist. Most works involved only onsite or facility scale or just considered certain environmental effect aspect. In addition, the lack of onsite monitoring data of water quality and quantity affects further research on low-impact development type of best management practices evaluation. In most emerging and developing countries, low-impact development type of best management practices implementation is still in the start-up stage. Quantitative life cycle assessment or life cycle cost analysis studies of low-impact development type of best management practices can provide necessary and useful information for decision-makers in regional scale low-impact development type of best management practices arrangement. Low-impact development type of best management practices database based on specific regions should also be established to support further in-depth research. Finally, low-impact development type of best management practices can offer various benefits to urban eco-systems. Researchers should provide a combination of environmental, economic, and social benefits of low-impact development type of best management practices to fulfill sustainability.
