In the excellent performance of each system development and the WEER system coupling coordination, downtown Suzhou had the best results
The closer the other areas were geographically to downtown Suzhou, the better the area performed
The development of this region should be government led and market driven with environmental protection as the primary premise to scientifically allocate regional water
resources, optimize industrial institutions, promote economic quality and efficiency changes, and encourage the use of renewable water resources
Downtown Suzhou needs to use the recycled water more fully to supplement water consumption for the river and lake landscapes
Different recycled water allocation schemes could change the coordination of regional development Since this study focused on the specific situation of the water resources, economy, ecological environment, and recycled water in five regions of Suzhou, it presented clear relevance In future research, the scope of the study could be expanded to improve the model, and research ideas with more comprehensive data information could be used to obtain the universality of the view that the utilization of reclaimed water can regulate the coupling coordination of the urban WEER system
