Özet:

Afforestation is an indispensable practice for the sustainability of forests in the absence of sufficient forest. Planting tree species compatible with local environmental factors will contribute to the strengthening and protection of forests. This study aims to develop a statistical model to determine the optimal growing areas of tree species compatible with local environmental factors using GIS. While creating this model, nine main environmental factors (lithology, landform, elevation, slope, aspect, temperature, precipitation, soil type, soil depth) that affect the distribution of tree species were determined. These factors were analyzed along with their sub-criteria. Analyzes were done using the AHP method. According to the analysis results, the distribution of tree species in the study area is affected by temperature, precipitation, elevation, slope, landform, and soil depth. The optimal growth areas of each tree species are quite different from each other. The results show that this method is easy to apply in forest planning and offers forest decision support systems opportunities to create a wide variety of alternative plans.
