Regional water resources assets accounting based on cyclic coupling perspective
To achieve regional water resources balance and promote coordinated development of socio-economy,and enhance the level of water resources assets management,this study systematically analyzed the evolutionary patterns of water resources system under multiple water circulation mode and the near and remote coupling of water resources elements,and proposed multiple classification methods of water resources assets accounting boundary.From the perspective of circular coupling,the water footprint analysis method is used to construct the water resource assets accounting model considering the combination of physical water and virtual water,and the water resources assets of each province,municipality and autonomous region in China are analyzed.This study is helpful to clarify the internal mechanism of the dynamic coupling of water resource assets under the dual-cycle pattern,expand the theoretical system of water resources accounting,and provide useful scientific reference for national and regional water resources assets accounting.
