Abstract: Following the comprehensive implementation of the river and lake chief system in China in 2016, the focus on protecting and restoring the health of rivers and lakes has escalated to become a central issue in water management. However, the processes for evaluating and supervising aquatic health face considerable challenges, such as high costs, inefficiencies, and regulatory obstacles, which hinder the ability to assess water bodies in real time. Guided by the 'Guidelines for Health Evaluation of Rivers and Lakes (Trial)', this paper investigates the dynamic evaluation and monitoring of river and lake health using high-resolution remote sensing satellites, covering four primary criteria: basin, water, biology, and social services. It introduced a novel remote sensing interpretation method for specific health assessment indicators of rivers and lakes, thereby creating a dynamic assessment framework based on high-resolution remote sensing imagery. The research enhances the development of digital twin systems for evaluating and managing the health of rivers and lakes, providing crucial decision support for intelligent assessment.
