The optimal regulation of water system is one of the key measures to realize the harmonious and sus-tainable development of human-water-ecology in water shortage stress area,which is of great significance to en-sure the stable development of regional economy and society and ecological health.In this paper,the Beijing-Tianjin-Hebei region is taken as a typical case of water shortage stress region.By analyzing the connotation of wa-ter system,it is concluded that the water system in the water shortage stress region has three phenomena:deep coupling,strong competition and system imbalance,and it is found that the water system presents an alternating e-volution pattern between unsteady and steady state.The state change and development process of the water system in the Beijing-Tianjin-Hebei region is evaluated by constructing the steady state index of the water system.In order to achieve the health of natural social water systems,a decoupling regulation model of"high cohesion-low coupling"is proposed.Based on the current situation of the Beijing-Tianjin-Hebei region,a hierarchical regulation of"ensu-ring rigid-reducing flexible-restraining luxury"is carried out on the water demand side,and the adaptation optimi-zation of"natural water network-artificial water network-virtual water network"is carried out on the water supply side,and the integrated water network layout of"three lines,seven rivers,four districts and eight sources"is pro-posed in the Beijing-Tianjin-Hebei region,so as to achieve the overall health of the water system.
