In this research, the soil stability, nutrient cycle and soil infiltration parameters were evaluated by LFA method in summer rangeland of Valuyeh Kiyasar in Mazandaran province. Eleven parameters of the soil surface were evaluated on the plant patches in 7 elevation points (with 100-meter interval) from 1600 to 2200 meters a. s. l, in north and south directions. The study was performed on 14 transects with 50 meter length at the dominant slope of the study area. The independent t test was used to compare the soil stability, nutrient cycle and soil infiltration parameters in north and south directions. In addition, the Analysis of Variance and Compare Means test were used to compare these parameters in each elevation point. The results showed that there was a significant difference between north and south directions in terms of soil stability and nutrient cycle parameters (P<0. 01). However, there was no significant difference in infiltration index between two directions. According to the results, infiltration in both north and south directions in different elevation points showed a significant difference at (P<0. 01), so that the elevation point of 2100 in both directions had the highest performance. On the other hand, results indicate the adaptation of the LFA method in this research and other researches, adding the accuracy and speed of this method as compared with other methods.
