- Abstract
Chinese cities have developed rapidly in the past several decades, and the urban water shortages have become increasingly severe. The use of recycled water can effectively alleviate the imbalance between urban water supply and demand. We selected five areas in Suzhou as the study area, and a coupling coordination degree model of the water resources-economy-environment-reclaimed water system in each district and county-level city of Suzhou was constructed and analyzed. The characteristics of the regeneration water configuration scheme that corresponded to the optimal coupling coordination degree were derived. Downtown Suzhou had the best integrated development and system coupling coordination, while the other areas performed better when they were geographically closer to downtown Suzhou. In addition, different reclaimed water allocation schemes could be used to regulate the system coupling coordination of the region. For the Suzhou downtown area, increasing the amount of supplemental reclaimed water from the river landscape was an effective solution for promoting this coordination, and an increase in the total amount of reclaimed water utilized in other county-level cities also improved the coordination degree. This study provides lessons and references on how reclaimed water utilization can improve integrated and coordinated urban development.
