AI Technical Summary
Traditional methods for calculating lake ecological flow rely heavily on measured hydrological data, making it difficult to obtain reliable results in lakes lacking long-term observation stations. These methods are also characterized by poor applicability, high cost, and difficulty in meeting the needs for rapid assessment.
A method based on remote sensing and water balance model was adopted. By acquiring remote sensing image data, meteorological data and digital elevation model, time series of lake area, precipitation and potential evapotranspiration were extracted. The lake inflow was determined by combining water balance model and ecological flow was calculated by combining lake type.
It reduces computational costs, improves timeliness, and enables rapid assessment of lake ecological flow, providing low-cost and efficient data support for the development, utilization, and management of lake water resources.
