System dynamics simulation for the coordinative development of socio-economy and environment in the Weihe River Basin, China

A reliable system simulation combining socio-economic development with water environment and comprehensively reflect a watershed's dynamic features is crucial. In this study, a complex system dynamics model is constructed to evaluate dynamic changes of socio-economic development and ecological...
