The Application of GIS in Selection of Suitable Species for Afforestation in Southern Forest of Caspian Sea

A. Eslami, M. Roshani and M. Hassani    

Abstract: The present study is conducted at the Shemroud water shade, Guilan province, which is located in north region of Iran. In order to investigation on ecological requirement of 16 species using GIS, the environmental conditions were determined in study site including elevation, slope, aspect, climate and soil. With concerning of importance of their categories, t he maps were classified with range of 1 to 9. The suitable environmental conditions for growth species assigned 9 value and unsuitable conditions for growth species assigned lower values gradually. Using Analytical Hierarchy Process (AHP) method, the maps were weighted with regard to mentioned affecting factors. Obtained results showed that there is different appearance for ecological range in per species. Finally, it was extracted final map model for afforestation using mathematical relationships and merging ecological models for each species.
