  Mountainous rangeland ecosystems have a highly delicate position in ecologic areabecause of severe environmental conditions and having wildlife and livestock. Knowing andrealizing the biotic and abiotic components, which have an interaction with each other in thisecosystem, perform the most important role in to desirable management of it. The systematicmanagement is one of the managing features such as modern approach for land managementand suitable use of upland ecosystems. To reach that, mountainous rangelands of Javaherdeh(Ramsar) via 1:25,000 scale map were selected. Density, rangeland conditions, vegetationcover, gravel and grit were determined by Superficial and modified six-factor methods, ArcGIS v.9.3 software was employed to achieve land form map which was obtained by thecombination of altitude, slope, and slope aspect maps. First, basic and first environmental unitmaps were changed with land form map into soil type map, and first basic map intovegetation type map. The proposal map of systematic management of area was associatedwith final environmental unit map into landuse map via their attribute table. The establishedproposal map shows accurate position of different future land uses on the basis of currentecological capabilities of areas. Around Javaherdeh village is suitable for extensive outdoorrecreation (7.59%) and appropriate for the grazing of livestock (62.22%). Some areas(20.07%) also should be protected because of landslides and debris formation. پرونده مقاله
