| Abstract | ||
| In Iran's desert, carrying out research into designating the interrelationship in geomorphological facies, land components and vegetation, as well as efficiently mapping such fields are quite essential. In this research the geomorphological facies, land components and vegetation types of the Mashhadardahal Basin in Kashan have been mapped and compared. The study's results indicate that the boundaries of the mountain geomorphological facies correspond with those of the vegetation types so closely that one can consider them overlapped. However, the land components in the soil map do not enjoy such high overlap because of regional debris as well as the soil being shallow.In the Piedmonts containing fairly thick to thick soil, the boundary of the land components corresponds with that of the vegetation types.In some cases, soil erosion brought about by human factors has resulted in incongruities in the indicated maps. A comparison of geomorphological facie's maps with the vegtation type ones in the research pediments signifies the fact that they show fair congruity with mountain maps. Therefore it is necessary to make a map in which the mountains and piedmonts share the boundary with the vegetation types, and that proves to be efficient. This research points out that one can make such a map through amalgamating geomorphological facies' maps (for the mountains) with the land component ones taking into account geomorphlogists' and pedologists' viewpoints and ideas. Moreover, considering the geomorphological facies as a base and benefiting from pedological views in analysing and amalgamating the facies it is possible to make a map of appropriate use in natural resources. | ||
