This paper adopted three periods of remote sensing images in 1973, 1993 and 2010, respectively, to establish the vegetation coverage index model based on the relationship between vegetation index and vegetation coverage, divided the grades of vegetation coverage using the technology of RS and GIS, and studied the process of dynamic change in recent 40 years. The result shows that vegetation coverage generally degraded Yuntai mountain area, but it showed the improving tendency in the local area; the grade of coverage in the core area was much higher than that in the surrounding area in the period from 1973 to 2010, but this advantage was declining; the change in the core area was less than the surrounding area, and the coverage change of the lower grade was more significant than the high grade, the vegetation coverage in core area was more stable than the surrounding area, the change of lower level coverage was greater than the high level coverage; in the first 20 years, the vegetation coverage mainly presented the trend of degradation, but it was restored gradually in the recent 20 years; the economic development models and the concept of ecological environment played important roles in the trend of the vegetation coverage change.
