Abstract: Effect of different patches and interpatch on infiltration rate was specified in an arid rangeland ecosystem with 188 mm annual mean precipitation in Yazd Province, central part of Iran. Different patches and interpatch were determined in the study area (shrub, iris and grass patches and bare soil as interpatch). Initial (first 5 min), final (last 5 min) and total (30 min) infiltration rates measured by using ring method and then compared together with a completely randomize experimental design. The slope of infiltration rate curves in shrub, iris and grass patches and bare soil decreased, respectively. Infiltration rate increased in shrub patch partially and approximately fixed in the other patches and interpatch after 30 min. The infiltration rate variations in patches and interpatch were different significantly. Iris patch had highest final and total infiltration rates. Iris and shrub patches had highest initial infiltration rate. Initial infiltration rate of the grass patch was lower than the iris and shrub initial infiltration rates. Initial, final and total infiltration rates of the bare soil (interpatch) were lower than the patches. Regarding to shrubs dominance and their high infiltration rates in arid rangeland ecosystems, we concluded that shrub species are the best choice for restoration of these areas that as ecohydrological patterns have a prominent role on reducing runoff, redounded to lower transfer of initial resources out of ecosystem.
