Özet:

This study is aimed at identifying changes in forest areas with the help of the Geographic Information System. The Denizli Forest Area Directorate, the Servak Forest Business Directorate, has studied the changes that occurred between the years 1990-2019 in the field of work specified as the Chamsu Forest Business Directorate. The study took advantage of the forest planning plans and maps made in the 1990s and 2013. Basically obtained 1990s maps were digitalized and the process of raster-vector transformation was implemented. After the geographical database of the land cover type identities have been edited, the 1990s and 2013s maps have been compared with the geographical information system software analysis and the exchange layer has been obtained. With the help of the geographical database of this layer, the exchange matrix was produced and the changes were calculated. In addition, the silvicultural applications made in 2014-2019 were also maped by entering the geographical database. According to the results obtained from the study, changes in different directions and sizes have been detected in 34% of the total area. In 2013, the forest areas increased by 484 hectares, about half of the forest areas under 10% of coverage turned into normal coverage and agricultural areas decreased by approximately 5%. In silviculture applications between 2014-2019 it is found that a total of 340 hectares of cranberries were planted, lighted and dissolved. The data obtained from this study shows that the Geographic Information System is a powerful tool that can be used in determining timely changes in forest areas. These systems, which can provide significant decision support to the implementers in forestry studies, can become an efficient forest information system by supporting data of forestry activities transmitted daily into the geographical database and remote detection data such as photographs taken from unmanned aircraft, air photographs and satellite images.
