Abstract

In this research, the status of forests in Ilam city with the aim of preparing the spatial distribution map of Oak forests degradation using Remote sensing and geographic information system was investigated. In order to achieve the extent and location of degradation in the studied area, the forest area map for using Landsat ETM+ Satellite Images and forest area map for using OLI Satellite Landsat images, Field visits and a method of determining educational samples were prepared. To investigate the factors affecting on degradation, first, the spatial variables including distance from residential areas, distance from roads, slope, aspect and altitude were extracted from topographic maps of: . Then the degradation location data of the region forests with the physiographic and human spatial variables was entered the model. For modeling and estimating the spatial distribution of degradation in the study area forests, Logistic regression and step-by-step method and forward step type were used. According to the results obtained from the statistical model, the development of human-made areas, population growth, reducing the distance of roads from the forest areas, the middle altitudes and reducing the slope percentage that triggered agroforestry activities and increase of agricultural land area had the highest impact on the degradation of the Ilam city forests, respectively. In fact, of hectares of forests in Ilam city, hectares ( ) have been reduced, of which hectares ( ) are related to the phenomenon of oak drying and hectares ( ). ) It is related to the construction of settlements, road construction, etc. Based on this, a spatial distribution map of the destruction of forests in Ilam city was prepared.
