Abstract :
The purpose of this study was to investigate the functions of plant structure in semi-arid rangelands of Takab, West Azarbaijan Province, using LFA. To do this, 11 soil surface characteristics were evaluated for assessing soil permeability, nutrient cycle and soil stability during 20 transects. In this study, a variety of patch and inter patch were detected. During each transect, five replicates of any type of ecological stain and bare soil were taken. Then, the factors measured in the form of three characteristics of stability, permeability and nutrient cycle in each type of structure were classified.The results showed that stability, permeability and nutrient cycling for the patches were respectively wheat bush (59.41, 68.46 and 68.17),Shrub-broadleaf (58.87, 64.33 and 61.49) Shrub (53.28, 31.62, and 60.43) and broadleaf_ grasses (51/16, 51/13 and 59/80). The results showed that the stability, permeability and nutrient cycle when the patch in the region are of the plant type is Bush -grass The condition is far better than other plant patch. The results of this study showed that short shrubs improved the parameters of rangeland performance, including stability, permeability and nutritional cycle. It can also be said that the denser the Bush are, the better soil-forming phenomenon.
