Classification Supervision and Optimal Grazing Problem of Grassland Grazing Area based on Improved SOM Network Model

There is an urgent need for scientific supervision and management of grassland pastures. This paper proposes to use drone photos of pastoral areas combined with the improved SOM network model to classify the pastoral areas shown in the photos, and then sample each index system of the actual small grassland in pastoral areas, and then use the SOM network model to classify the sampled samples, and the results can be used to correct the previous classification results. The modified SOM network model can be used to classify and supervise the management of large grazing areas in practice. Then, according to the law of plant growth, the plant growth model and the benefit optimization model of pastoral area were established to realize the ecological balance and benefit optimization of pastoral area.
