The compare of assessment rangeland condition with soil properties method and 4 factors method in shrublands of Golestan National Park

Determine of rangeland condition is one of the important factors which applicated for management and using of rangelands. For determination there are different methods rangland condition. New concept of rangeland condition is based on the premise that the most important and basic physical resources on each rangeland ecosystem is the soil. In this paper used to soil surface condition for determine of rangeland condition. For determine of rangeland function selected Shrubland sites National Golestan Park in heavily,moderate and ungrazed areas. 5 transect 100m located within areas. 10 lm2 quadrats were systematically placed along each 100m transect. Totally 150 quadrats placed in all aeras for assessment soil surface properties. The result of study show that different between rangeland function analysis and 4 factors method is significant. In this research presented model for determining of rangeland condition by aspect to soil surface and vegetation properties in the moderate and heavy grazing areas.
