Econo-environmental Evaluation of Rainwater Management Measures based on Entropy Weight Method —— a Case from Beijing
Pages 93 - 97
Abstract
The challenge of urban waterlogging is tremendous and urgent, calling for a transition toward water-resilient urban governance. In the context of sponge city construction in China, this study established a comprehensive evaluation system for rainwater management measures based on their economic and environmental cost and benefits. Using Beijing as a case study, the econo-environmental evaluation model was applied to comprehensively quantify the benefit of various portfolios of rainwater collection and utilization measures. The entropy weight method was used to weight evaluation indexes. Results show that the portfolio of “roof greening, permeable pavement, rain-collecting green space, grass-planting shallow ditch, and reservoir” has the greatest comprehensive benefits, and is the best rainwater solution among case projects. The econo-environmental evaluation model contributes to robust decision makings in urban water management and promotes the construction of sponge cities in China.
