Speech Title: Optimization of Green-Grey-Blue Coupling System for Sponge City Construction
Abstract: Sponge city construction is one of the national policies and action in China, which aim to uses natural and ecological methods to retain rainwater, alleviate flooding problems, reduce the damage to the water environment, and gradually restore the hydrological balance of the construction area. The kernel of Sponge City is to develop a coupled green-grey-blue system which consists of green infrastructure at the source, grey infrastructure at the midway and receiving water bodies as the blue part at the terminal. In this talk, sponge city concept and policy in China was described first. Then several case studies on how to assess the comprehensive performance of a coupled green-grey-blue system and then how to optimize it were introduced.
