Temporal and Spatial Distribution of Chlorophyll A in Urban Estuaries Studied Using Satellite Imaging

Estuarine cities are affected by watersheds, oceans and local human activities, and their water bodies are facing pollution and eutrophication problems, causing great pressure on urban ecology, production and life. Therefore, it is very necessary to monitor their environment. In this paper, we analyse the advantages and limitations of satellite remote sensing technology, effectively invert the chlorophyll A concentration and turbidity of urban water bodies, accurately track the temporal changes of eutrophication, grasp the driving mechanism and spatial pattern, and achieve the dynamic tracking of the pollution diffusion path and eutrophication range through the temporal remote sensing data, and further quantitatively assess the implementation effect of ecological restoration projects (e.g. wetland restoration, sewage control), to provide an opportunity for the study of environmental monitoring of urban inland water bodies. It provides reference and reference for the study of environmental monitoring of urban inland water bodies and points out the important points to note in the application of satellite remote sensing in ecological environment monitoring and improves the ability to monitor the ecological environment.
