Abstract

The invention provides a remote sensing identification method and device for grassland salinization and a computer readable storage medium, and belongs to the field of a remote sensing technology andenvironment survey. Preprocessing is carried out by existing salinization data, spectral features are obtained and used as feature input quantities, then computer learning is carried out, and an identification model is established; data of a to-be-detected region is identified by the model to obtain a salinization region; the identification device for salinization can rapidly and accurately identify the salinization region; and the computer readable storage medium can conveniently execute the identification method to obtain related data and then obtain data of the salinization region.

Description

technical field [0001] The invention relates to the field of remote sensing technology and environmental investigation, in particular to a remote sensing identification method, device and computer-readable storage medium for grassland salinization. Background technique [0002] There are usually two ways to identify salinized areas. One is the method of obtaining soil parameters through field sampling, and the apparent conductivity of the soil is measured by an electronic induction conductivity tester, and finally the salinization situation is evaluated; the other method is through the interpretation of remote sensing images. Field sampling technology is mature and has high precision, but the acquisition cost of data sources is high, and it is difficult to monitor and identify a large area. The data of remote sensing images are easy to obtain, which is conducive to large-scale identification, and has the characteristics of multi-band and multi-time span. [0003] By combin...
