Dynamic Interactive Map-based Dashboard Design for River Management in the River Chief System
In the context of ecological civilization construction,the comprehensive implementation of the River Chief System has become a powerful measure for China to address complex water problems and maintain the ecological health of rivers and lakes.However,there are still some issues,such as insufficient theoretical research and a lack of design methods for river management maps based on the River Chief System.To address these issues,we have explored the following aspects of research.Firstly,this study interpreted the connotation of the River Chief System from four aspects:organizational structure,river chief responsibilities,main tasks,and supervision and assessment.From the perspective of maps,we analyzed the information transmission and mapping requirements of relevant departments and river chiefs at all levels.Based on the thematic map theory,the concept of a river management map is proposed,and its characteristics were summarized.Building on this,we proposed the design concept of"multi-department collaborative linkage and multi-level river chief task decomposition"from both horizontal and vertical coordination dimensions,thereby establishing a content framework for river management maps.Secondly,based on the theory of geographic scenarios,this study summarized and analyzed the elements of time,place,people,things,events,and phenomena in river management scenarios.We proposed that river management maps should select appropriate spatiotemporal scales,representation methods,visual variables,user interactions,and communication media for user groups to guide the selection of mapping expression content for each map group.The presentation forms of information in the river management dashboard map mainly include maps,information charts,and forms,which were also classified and organized in this study.Then,based on the application scenario of the map,this study adopted an interactive dashboard format and electronic screens as the communication medium,utilizing the five elements user experience model and drawing upon theories of cognition,visualization,and map interaction to design the information architecture,interface layout,color scheme,information presentation,and interactive features of large-screen maps.Finally,taking Baoshan District,Shanghai,as a case study,a river management dashboard map system is designed and implemented,followed by a systematic usability evaluation.The results indicate that the dashboard map supports the display of multi-scale river management information,facilitating clear visibility of target information for users.The aim of this study is to actively contribute to the standardization and regularization of river management maps tailored to the River Chief System,facilitating multi-departmental collaborative management and promoting co-construction and resource sharing.
