Vegetation coverage is often used as an important indicator to detect vegetation status. Therefore, the spatial and temporal dynamic changes of vegetation in a region can be studied by estimating vegetation coverage. In this paper, remote sensing image preprocessing operations are performed on the two phases of TM remote sensing images in 2007 and2016, and vegetation coverage maps of different phases in Anqing City are obtained. Using the vegetation index method to calculate the vegetation coverage of vegetation coverage at two different phases of 2007 and 2016 in Anqing City, the vegetation coverage of two phases in Anqing City is graded according to the national standard for the coverage of vegetation coverage. The final result shows that the vegetation coverage in Anqing City during ten years from 2007 to 2016 changed greatly,and the area of extremely low and low vegetation coverage grades show a decreasing trend, and the areas of medium, high and high grade vegetation coverage increase significantly. It shows that in the 10 years, the vegetation and biomass of Anqing City have been increased obviously and the ecological environment has been improved.
