Abstract: In order to overcome the problems of low accuracy and the time-consuming nature of traditional vegetation distribution monitoring methods, a new monitoring method of surface vegetation distribution in the Yellow River Basin based on remote sensing image segmentation is proposed. First, describe the segmentation features of remote sensing images. Secondly, based on the results of feature description, H-minimum transform is used to calculate the segmentation parameters of remote sensing image and complete the segmentation of remote sensing image. Finally, the maximum value synthesis method is used to calculate the surface vegetation coverage. Combined with the normalised vegetation index, the dichotomy model is used to calculate the distribution parameters of surface vegetation, and the distribution monitoring of surface vegetation is completed. The experimental results show that this method can effectively improve the monitoring accuracy and reduce the monitoring time, and the monitoring accuracy reaches more than 93%.
