Weihua ZENG,Bo WU,Ying CHAI

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 1,   Pages 114-128 doi: 10.1007/s11783-014-0669-6

Abstract: Feedback loops can be analyzed to increase the water environmental carrying capacity (WECC) of the newurban water metabolism system (UWMS) over that of a traditional UWMS.feedback loops of an UWMS was used to construct a system dynamics (SD) model for the system under a WECCA sensitivity analysis showed that the WECC could be improved to some extent by constructing new sewageand improving the water circulation system.
