Identify and Evaluate Beneficial Fires in Forest Areas using Satellite Imagery
(Case Study: forest fires in Golestan province in 2011)
Abstract
With a little daring، it can be said, Fire is the most dangerous enemy of the forest. Thousands of hectares of trees, shrubs and plants burned every year and they are destroyed. Of course, the benefits of a controlled fire should not be hidden. Only strategic management can determine the usefulness or the harmfulness of a fire. In this regard, remote sensing technology can provide useful information on environmental conditions. The index used in this study is to show the health status, extent and density of NDVI plants, which is one of the common indices of studying plants in remote sensing. In this research, using vegetation index analysis, we process satellite images of fire areas. By evaluating processed images, areas that identify a type of surface fire. Ultimately, with specific techniques, the area of the fire will be determined. As a result, a total of 11250 hectares of forest land has been burned in Golestan province. Of this amount, 7625 hectares of surface fires. Because there is not much damage to the forest area, and next year we saw an increase in NDVI and more regeneration in the forest, Therefore, it can be said, this is a controlled fire and it is a kind of useful fire.
