Abstract

The world around us is very diverse physically, biologically, culturally, and so on. These diversities have provided us with many advantages so that by employing them, we can get short-term, long-term and sustainable benefits. Given the importance of the sustainable use of resources, it seems that the first step towards this purpose is identification and scientific study of these resources. Since 1990s, geologists and geomorphologists began to use the term geodiversity, which led to opening of a new direction in studies related to this subject. Given the importance of identifying potentials of geodiversity and the need for its conservation and sustainable use, this research aimed at analysis of geodiversity and its conservation and sustainable use. To this purpose, the study area based on its natural properties was divided into 3 classes. Then, for each of these classes, determinants features of geodiversity, including geology, hydrology, soil, etc., were investigated and the geodiversity index was calculated. The results showed that Class 1, located at the north of the basin, had the highest geodiversity index (6.59), mainly because of existence of calcareous formations and various geomorphologic forms, and the smallest index value (2.9) was calculated for the Class 3, which is mainly formed of alluvial deposits
