Survey features structure and function ecological patches rangelands in several levels of management in National Golestan Park

For scientific management and correct on rangelands ecosystems, relieve information from topics health indicator and function is necessity. Assessment rangelands ecosystems opposite reactions of environment and management for beneficiaries this type of ecosystems is high importance. The National Golestan Park and its rangelands environments with consideration to kind of management (conservation) can be had different perspective structure and function. Therefore, Therefore the aim of this research is Survey features structure and function ecological patches rangelands in three areas area national Golestan parks, Ghorkhoud protected area and Espakhoo area. With this purpose in every of study area eastern Hill slope is surveyed on three, 50 meters transects in point dominant Hill slope, patches and inter-patches in 3 frequencies. By Using of model LFA (Landscape Function Analysis) is surveyed three features function (soil stability, permeability and nutrient cycle) and features structure (numbers of patch, total patches area, patches area index, indicator of Landscape). The result of study shows that more structural attributes (mean length patch, number patch, mean width patch, total surface, indicator of surface patch and indicator structure) in national park area is more from Ghorkhoud area and Espakhoo.  On opinion stability indicator different between national park area and Ghorghoud was not significant (p<0/05). In national park area and Ghorkhoud is the highest function indicator related to ecologic paddock of grass+forb and in Espakhoo area is the highest function indicator is related to ecologic paddock shrub+forb. From features structure and function can apply early perceptions for determining of destruction rangelands and this through necessary emprises available for preservation of intensity destruction or improvement of qualification.
