Coastal zone protection value accounting method based on remote sensing recognition for GEP accounting

The invention discloses a coastal zone vegetation spatial distribution characteristic identification method based on a landsat image and decision tree classification method. The method comprises the following steps: screening and obtaining the landsat remote sensing data; the remote sensing image is preprocessed to achieve the expected effect of ground feature recognition; according to the characteristic spectrum and construction calculation of different models, identifying characteristic ground features; and classifying the vegetation by using a decision tree classification method so as to research and analyze the spatial distribution characteristics of the vegetation in the coastal zone. By adopting the method, large-area synchronous observation can be realized, the problem of field investigation is solved, and the coastal zone vegetation distribution characteristics are accurately extracted so as to calculate the coastal zone protection value, so that ecological restoration protection, scientific research
