Abstract

Performance of studies in the North regions of Iran in order to get proper management, sustainable exploitation and land restoration is fully necessary. In this way, recognizing the plant species and their reaction to climatic, soil and living factors enjoying a special status. Among the great watershed areas, Haraz watershed has a specific ECOSYSTEM that resulted to a different picture of vegetation. In this research, considering the appearance reasons of these plants, that mainly are calciphile, gypsophile, saliniphile, was carried out by choosing one of the sub-catchments of the Haraz watershed named Razan watershed that holds the conditions. In this research, through the study of geology, petrology, geo-morphology, pedology, vegetation, topography and meteorology, it was tried to recognize this special ECOSYSTEM. The results of the study show that the major factor of these plants development at first was the general topography of the region, secondly the petrological specification of the area and finally the lack of rich and developed soil. About the topographical condition, it can be said that this factor acts as an obstacle against the humid and rainy aerial blocks, partly preventing the transition of these blocks or changing their routes. Little raining on the lowlands and alluvium terraces causes unleashing of salts created and at the most, causing the increasing concentration of salts and eroded minerals, which in addition to the above mentioned factors, resulting a special plant coverage in this region, and generally all these factors causing the creation of micro-climate, and particular ECOSYSTEMs among the valleys of Haraz, Chaluse, Sefidrood, and some specific regions of the North parts of Iran. The studying area known as Razan basin is about 14000 ha and its geographical coordinates is 52°.8' to 52°.18' Eastern longitude and 36°.1' to 36°.15' norther latitude. The area is a part of south of Nour city in Mazandaran province from the viewpoint of state political-administrative division.
