Assessing the Aesthetic Quality of Natural Landscapes GIS Based (Case Study: Varzqan County)

A landscape consists of two dimensions, natural and man-made, and is one of the most important components of a visual representation of the human-environmental relationship. Natural has undergone many changes. The purpose of this study is to evaluate the aesthetic quality of natural landscapes in the years 1363, 1381, 1398. The nature of research is developmental-applied and descriptive-analytical. Data were collected through library studies, questionnaires, and field surveys. The quality of landscapes was evaluated with the DEMATEL-ANP model. Considering three criteria (uniqueness, naturalness and diversity) and not sub-criteria, in the layers: (tourist places, mines and industries, Arasbaran forest area), for the first criterion, (land cover, Activity centers, ground surface temperature) were prepared for the second criterion and (land cover diversity, land structural diversity, elevation and elevation) for the third criterion. The relationships between influence and governance of the sub-criteria were determined by Demetel method and then analyzed by ANP method in Super Decision software. Finally, using ArcMap software, the beauty quality map of landscapes Was drawn. The results obtained from the final weight of the effective factors by ANP_DEMATEL method show that the highest coefficient belongs to the natural factor of land cover with a weight of 0.385736 and the uniqueness of the land cover with a weight of 0.169653, which indicates a clear display of the cover. The green landscapes of this region are considered by experts as an example of society. And the obtained maps, entitled the quality of the beauty of the landscapes, show the trend of quality reduction from the west to the east of the city. This decrease in quality can be felt in the lands located near the Sungun copper mine and the two populous cities of Varzeqan and Kharvana.
