Özet

Land cover change and its temporal trends were assessed between 1985 and 2000 in an area in northeastern Florida primarily covered by pine plantations. Landsat imagery was the principle sensor employed and the image processing techniques included the normalized difference vegetation index and a combination of supervised and unsupervised classification techniques. Results showed that during the 15-year period, mature pine plantation cover and young pine plantation cover declined by 9 percent and 2 percent, respectively, while open field increased by 10 percent. It was also determined that wetland forests declined by 5 percent. Because trees serve as highly efficient carbon storage devices, the decline in forest cover (pine plantation and wetland trees) leads to increased pollution of the atmosphere with carbon dioxide.
