A Study On The Behavioral Simulation And Guiding Strategies Of Urban Residents' Water-Use In Beijing

With the rapid development of China's urbanization,cities and towns have become the most important living and productive space for human activities,and the resources and environment supporting conditions for their development have become increasingly severe.Among them,water shortages have become a shortcoming that restricts urban development.The size,structure,economic level,awareness of resource protection and resource utilization methods of urban population affect the total urban water consumption.Beijing is in a temperate monsoon region,and water scarcity has become the biggest bottleneck restricting its development.The South-to-North Water Transfer Project can alleviate regional water shortages to a certain extent.However,in the face of continued population growth and economic development demands,the regional water crisis still exists.Therefore,how to coordinate the contradiction between rapid urbanization and water scarcity,improve the behavior and methods of urban residents' domestic water use,improve water resource productivity,and implement redline control of total water consumption are the keys to achieving sustainable development.Under the guidance of the water saving first concept,based on the social impact theory and the degree of involvement theory as the framework,based on the Agent Based Modeling method,a simulation model of Beijing's urban residents' living water behavior characteristics was constructed complex adaptation systems.By refining the different agent behavior rules of urban water users in Beijing,this paper explores three key characterizing parameters that influence the behavior of urban water users in Beijing: involvement coefficient,learning ability and information radius,and introduces deep learning to optimize the behavior of water users in changing environments.The algorithm simulates the optimal water-saving path for residents' water consumption behavior from the perspective of sustainable development.The research results show that residents' decision to save water will be optimized as individuals become involved in water-saving events.Improving the learning ability of residents' water subjects will obviously lead to higher water-saving levels,and the cumulative effect of water-saving levels will become more pronounced over time.However,the ideal water-saving state of the simulation does not appear in the range of the highest learning capacity of the residents' individual water use,and it will even decline in the later stage of the simulation.At the same time,the water-saving peak in the simulation cycle always appears in the range of the shortest path,and decreases with the increase of the simulation distance between individuals;in the first four years of the simulation cycle,the water-saving level increases rapidly,and then enters a gentle state.According to the research results,this study proposes the following four guidance strategies,with a view to providing reference for improving the water-saving level of urban residents in Beijing.First,improve the publicity content,improve and improve the residents' awareness of the current situation of Beijing's water resources;second,make full use of the online platform to expand the water-saving information publicity path;third,optimize the water settlement bill,and improve the information through timely feedback Residents' learning ability;Fourth,promote the development of watersaving appliances industry and promote the popularization of water-saving labels.
