Abstract

In order to check the amount interception and also the effect of the amount and intensity of precipitation and the percentage of canopy density of species Petropyrum aucheri, Scariola sp on the amount and percentage of interception in order to be productivie for soil protection in this study at the Faculty of natural resources and environment Birjand at 9 month ( September2019 to June 2020) has been done. Precipitation was measured under the species after each precipitation event. Also, during the autumn to spring, the canopy surface of the species was photographed vertically and their effective area was calculated. Then, the correlation of values, regression analysis and analysis of variance related to each of the parameters in Spss was investigated. According to the results, the highest and lowest percentages interception are equal to 32 and 11 percent, respectively, related to Scariola sp. The total annual interception for Petropyrum aucheri and Scariola sp species was 30/4 and 55/1 mm respectively. The results of regression analysis showed that there is a linear relationship between the amount of precipitation and the amount of interception of the petropyrum aucheri species (R2=0/827). There is a linear relationship between amount interception and percentage density of petropyrum aucheri species (R2=0/73). There is linear relationship between the amount of rainfall with amount interception Scariola sp species (R2=0/63).
