Analysis of the Vegetation Coverage Condition in Nearly Five Years in Yangzhou Using Remote Sensing Monitoring Technology

Using the remote sensing data of Yangzhou in recent 5 years,study on the condition of vegetation coverage have been carried out.First of all,geometrical correction of the remote sensing image;then,interpret these remote sensing images,extract the information of vegetation coverage and calculate the index of vegetation coverage.At the same time,the dynamic variation analysis for the condition of vegetation coverage for nearly five years has been studied.Research shows that forestry area is greatly improved in five years,and vegetation coverage index is increasing year by year.So the ecological environment situation of Yangzhou is getting better gradually.
