Method of Estimating Vegetation Coverage Based on Remote Sensing

With the development of remote sensing,vegetation coverage,which is a quantitative parameter for vegetation growth and coverageconditions,has been widely applied in the fields such as agricultural,environmental and ecological studies.This paper has introduced the important role and significance of vegetation coverage,and narrated its research status and remote sensing data sources.Besides it also discussed the methods of estimating vegetation coverage based on remote sensing data and its advantages and disadvantages mainly from the statistical model,physical model,FCD model and so on.The future trend of its study has been prospected.
