Abstract

Geodiversity is the geographical variety of materials, forms, and terrestrial processes that make up the planet Earth. Land diversity is a basic term to determine the importance of non-living resources of nature, therefore, the expansion of studies related to geodiversity, especially in Iran, which has a lot of geological and geomorphological richness, can open a new window in the field of understanding the natural potentials of different regions of the country. One of the effective and potential goals in tourism is geological diversity or geodiversity and more importantly, geomorphological diversity, which can be considered as the main foundations of tourism in Iran. Arjan Plain, which is located 60 km southwest of Shiraz in the fold zone of the Zagros, is virgin and important from the point of view of tourism due to the presence of various karst forms such as Cheshme, Dolin, Lapieh, Punor, Hams, Cascade, Teng, and Dareh. In this research, an analytical and practical research method has been used. Geodiversity indicators were carried out in ARCMAP, Fragstats software environment, and the results of the research showed that in the southern part of Polie Arjan, the GDI index is equal to 11.04. Due to the mountainous topography and higher altitude, more rainfall, and lower temperature, and on the other hand, the presence of the Asmari limestone formation, many and varied forms of karst have been developed in this section, as well as the SIEI, SHEI, SHDI, SIDI, MSIDI, MSIEI is equal to 1.56, 0.87, 0.77, 0.92, 1.47 and 0.82, respectively. It has caused the expansion and diversity of geodiversity in the region.
