عنوان مقاله [English]
The term geodesy is equivalent to morphological diversity. When it comes to geological diversity, it refers to global concepts of geological diversity and geomorphologic diversity, and we briefly call it geological diversity, and includes a variety of geological diversity, Mineralogy, Stratigraphy, Lithology, Sedimentology ... And with the new Global Approach to Geodesy, the protection of geodesy in the form of the preservation of inanimate nature with the advent of the geoscience world in the world (2008) has been raised, without the existence Geological diversity will be meaningless to protect Geocaching. Natural resources, such as building stones, grains of grains, minerals, natural gas, oil and underground water, are the basis for human beings; it forms the basis of agricultural land and fertile soils; affects our place of life. Enhances our valuable and special environments; an unprecedented archive of climate and past environmental conditions; there is also no rich cultural heritage and history of geodatourism without biodegradation;
In the meantime, the necessity of attracting tourism to Iran with this regional scope and the many potential that exists to create income and employment and sustainable development is felt on the other hand, Iran, in terms of unique geological and geomorphologic phenomena among the richest The countries of the world and has a great potential for achieving sustainable development in this way. According to forecasts, there are 50 potential areas for identification, establishment, exploitation of tourism, educational and sustainable in Iran for global geopark registration.
In this study, in order to study the geodesy of the three Fahliyan basin, Nurabad and Rostam basins which are located in the south of Iran in the northwest of Fars province and the central and eastern parts of the city of Noorabad Mamsani and Rustam, these basins total area of ââ 2005 sq. And geologically, these basins are considered to be corrosive Zagros. Located 935 meters above sea level and 150 kilometers northwest of Shiraz, is located in the center of Fars province. The studied area is located in the Zagros zone in terms of the geological units of Iran.
In this research, a descriptive and analytical research is descriptive. First, morphometric, morphological, and geological classification layers were prepared. Geological layer of 1.100000 geological maps, morphoclimatic layer of Iranian climatic layer and morphometric layer using altitude layer using TPI index, which is described below. At the end of the layer, the final composition of the three-layer combination The original was created. After this stage, using FRAGTATSE software, five geodecimal indicators including PRD, Simpson roughness coefficient (SIEI), Shannon roughness coefficient (SHEI), Shannon coefficient of Shannon (SHDI), Simpson Diorsity coefficient (SIDI) Calculated. The FRAGTATSE software was used by McGarig in 2002 to calculate geodeiversity.
Table 4 shows that at the end of the stage and the combination of three morphometric and morphological characteristics of the morphological and morphological characteristics of Simpson and Shannon in Nurabad basin has the highest rate and the same indices in Fahlian and Rostam basins are relatively less. On the other hand, due to the fact that the northern watershed has a wet climate and this region has the highest rainfall in terms of rainfall, and its average annual temperatures are much lower than in other regions, which in some way promotes the development and expansion of morphometric diversity And the rippling variation in the basin level. This has led to the formation of very tall walls of numerous waterfalls, valleys and troughs in the southern parts of the country, and also the water resources in these formations are far more expanding and expanding gardens and forests. Wide
The results of the indicators applied in each of the three basins are shown by examining the geological status and type of formation in the three studied basins, considering that the diversity of the Formation in Fahliyan is 12 types in Nurabad 10 types and in Rostam 9 this is a kind of determination The high point is the index of Shannon and Simson's variability and roughness indexes in Fahlian Basin. Because the Fahlian Basin has more chasmas than other basins in the Earth's Factor (Mesozoic and Cenozoic limestone formations). In morphometric factors and the final layer of geodesy, the highest value is attributed to the noradabad basin due to its high slope, altitude, roughness and degree of curvature, as well as the presence of wet climates in its southern parts, has led to the development of diverse forms in the region. In this basin, the Shannon and Simpson roughness indexes are equal to 0.307, 0.096, 0.097, and 0.777 respectively. Since geologists have sought to know more about land and access to information and to solve their uncertainties over the years, they have been neglected by Georgetowns and have not had much time to explore the diversity of land. However, it can be said that by examining the world of The geological diversity perspective can be better off than the natural resources of the earth. Despite the importance of geological diversity in various dimensions, this phenomenon is threatened by human activities. Therefore, the need to protect geological geogonality is felt and this is important for the development of geotourism. Protective objectives and practices should take into account different elements of geological diversity, and appropriate planning is appropriate for the Zeusite type. Management in geotourism and The related recreational activities as well as geoparks often depend on the type of geological diversity
