Theory and pattern of optimal regulation of water system in water shortage stress area
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.
