DDesigned and undersigned fires in rangelands affect vegetation and soil, and then are necessary to give enough knowledge about them. Infiltration is one characteristic that have predict had affected by fire but had not studied enough yet. So spot fire have been seen in Artemisia aucheri type in Charat sub watershed at Mazandaran province, in this research were investigated primary, final infiltration and infiltration rate in different intensities and seasons. For this prepuces first were established tree 100m transects randomly and then tree 2m2 plots on each transect. Fire treatments in plots following without fire, light surface fire as much as direct burning and without flammable material of plants and surface litter (without ash product) and intense surface fire as much as direct burning of flammable material of plants and surface litter (with ash product). In the next stage was measured infiltration in different seasons using double rings. Data analysis of primary, final infiltration and infiltration rate in different intensities and seasons was carried out using two ways ANOVA and compare means test in SPSS software ver.20. Results were shown that primary, final infiltration and infiltration rate are more in summer than the other seasons and are 5.224, 15.534 and 7.756 cm/hr respectively. Infiltration in area without fire had no significant different by area with light fire but amount of final infiltration in area with intense fire was fewer than other seasons as was reduced from 3.946 to 2.447 cm/hr.
