Abstract Vegetation coverage is a very important ecological environment parameter, and remote sensing imagery can
provide the vegetation coverage information and variation trend on different spatial scales. Remote sensing is an
important means in obtaining vegetation coverage, and vegetation indices are indirect indices which can reflect
vegetation cover and biomass. The methods for estimating vegetation coverage based on vegetation indices include
experiential models, vegetation indices, pixel unmixing analysis and FCD (forest canopy density) mapping model, and
the methods for estimating vegetation coverage based on decision tree classification and artificial neural network
have made some progress as well. This paper has analyzed and discussed the present methods for estimating vegetation
coverage based on remote sensing imagery as well as their advantages and disadvantages. The future trend of
vegetation cover study based on remote sensing technology is also discussed in this paper.
