The invention relates to a land use classification rule set, a water and soil loss monitoring method and a system. The purpose of the present invention is to provide a land use classification rule set, a water and soil loss monitoring method and a system. The technical scheme of the present invention is: a land use classification rule set, which is characterized by: S1, generating DOM and DSM according to aerial image data; S2, segmenting DOM based on multi-scale segmentation; S3, based on the spectrum of aerial image data, The shape, texture features, and the height features of the ground objects provided by DSM are used to classify land use to obtain the current status of land use. The invention is suitable for the technical field of water and soil loss monitoring, and is especially suitable for monitoring surface erosion in hydraulic erosion. |
