Abstract

Abiotic factors, as topographic and PHYSICOCHEMICAL PROPERTIES of SOIL, are the most important effective factor on vegetation in rangeland ecosystems which have the most important performances to forming and succession of plant vegetation. Ecologic management of rangelands can be desired by better understanding of these effective factors. Then, rangeland of JAVAHERDEH (Ramsar) in the NORTHERN ALBORZ Mountains ranging 2000-3200 m a.s.l. was selected in this study and altitudinal classes of 300 meter were selected to obtain field records on the basis of field monitoring and plants structures. About 15 plots (1 m2) in each altitudinal class were considered in order to obtain the field data, e.g. percentage of life-form covers. It was also chosen five plots to gather SOIL samples. Statistical analyses, using cluster analysis, DCA and CCA, were done by PC-Ord V.5.1 software. The results showed that life forms of plant under 183 species and 33 families have been divided into five sub-associations so that their segregation is done based upon elevation, aspect, and SOIL properties. Multivariate analysis (CCA) also can as well divide the life forms of plants based on their ecological requirements into subgroups include annual and perennial grasses with perennial forbs, annual forbs, shrubs, and bushy trees. These life forms are also found different ECOLOGIC NICHES funded upon influence of the topographic factors and PHYSICOCHEMICAL PROPERTIES of SOILs. Hence, ecologic management of terrestrial ecosystems needs to knowing and understanding of vegetation structures under different environmental factors.
