Lake water eutrophication monitoring method, device, equipment and medium

The invention provides a lake water eutrophication monitoring method, device and equipment and a medium, and relates to the technical field of remote sensing monitoring, and the method comprises the steps: obtaining a remote sensing image, carrying out the preprocessing of the remote sensing image, and cutting the remote sensing image to determine a to-be-monitored lake water region; carrying out cloud identification processing on the remote sensing image of the lake water area to be monitored, and removing image data samples of which the cloud coverage rate of the lake water area exceeds a preset threshold value to obtain a target data sample; performing water body identification processing on the target data sample based on the water body index, and constructing a lake water quality calculation model for the water body part; and according to the lake water quality calculation model, determining a lake water eutrophication state index of the to-be-monitored lake water area, and carrying out water eutrophicat
