In this paper, local areas on both sides of the Yellow River estuary are selected for Spartina alterniflora monitoring. The results are shown in Figure 4. The prediction results obtained by using the data set fused with vdvi index characteristics can effectively improve the model's misclassification of green water pixels into Spartina alterniflora, so as to better capture context information, so as to maintain the integrity and smoothness of patch edges, At the same time, it can effectively overcome the confusion between shadow and other background environment and Spartina alterniflora, and reduce the small gaps in the classification results.
