In Qingpu District of Shanghai,the"Blue Pearl Chain"features an intricate network of rivers and lakes,representing a typical lake area in the Yangtze River Delta Integrated Development Demonstration Zone.To comprehensively reflect the ecological environment of water bodies in the demonstration zone and establish a distinctive health assessment system for its rivers and lakes,this paper uses the"Blue Pearl Chain"as a case study.Guided by the Technical Guidelines for River and Lake Health Assessment of Shanghai(Trial)(DB31 SW/Z 001-2023),the paper evaluates river and lake health from five aspects:flow safety,scenic appeal,water cleanliness,ecological health,and social services.Results show that the health status of the"Blue Pearl Chain"lake area scored 77.89,indicating a healthy state with a relatively good regional water ecological environment;however,issues such as water quality and eutrophication remain.The findings provide a technical reference and decision-making basis for river and lake health assessments,as well as for the development and conservation efforts in the demonstration zone.
