Abstract: To address issues related to insufficient monitoring coverage, inaccurate measurement of pollution concentration, and inadequate load monitoring using traditional methods, an intelligent monitoring method for agricultural non-point source pollution based on remote sensing image changes is proposed. Utilising Landsat ETM+ remote sensing imagery, a multi-layer perceptron algorithm is employed to detect and identify agricultural non-point source pollution areas. The Min-Cut algorithm is used for remote sensing image segmentation of agricultural non-point source pollution targets. Remote sensing image changes are detected based on the segmentation results and difference diagram. Intelligent monitoring of agricultural non-point source pollution is achieved by combining the detection results of remote sensing image changes with relevant monitoring indicators. Experimental findings demonstrate that the proposed method achieves a monitoring coverage rate exceeding 96.3%, the mean accuracy of pollution concentration monitoring is 97.1%, the maximum accuracy of pollution load monitoring is 99.3%.
