Restoring the Mother River back to the City: Puyangjiang River Corridor in Jinhua

Abstract

As a pilot project of water treatment in Zhejiang Province, the Puyangjiang River Corridor project has remediated the polluted river course into a popular ecological and recreational corridor. The project restored the aquatic ecosystems and improved the water quality by introducing a constructed wetland system which purifies the irrigation water and the tributaries of Puyangjiang River. Under a concept of Sponge City construction and a minimal intervention strategy, the design not only enhances the flood resilience, but also minimizes the disturbance to natural ecosystems of the site. In addition, the existing agricultural, water-conservational, and cultural heritages have been preserved and partly reused as recreational structures and facilities, contributing aesthetic and educational values to the site.
