Soil and forest are one of the most important natural resources in each country. In fact, they determine the progress line or the backward one in each society. In accordance with geographic , as Iran is located in dry region of the each and the average of annual rainfall in its vast area is less then 100mm, the large amount of forests and pastures are going to be vanished. This may also be because of human's interfere and unsteady logging. According to identifying the soil faculty and its production ability, we may protact it by using correct and scientific ways. The identification and application of some types which are involved in forest revival and construction projects in dry and semidry regions, are very important. The main goal of this research is to consider physical chemistry qualities of area in Narmashir- Bam in order to find a relationship between physical and chemical charac traics of the soil. In order to gain this aim. Two kinds of vegetative mantle soil were chosen, One of mantle ( No.2 soil). These effect were noted according to the changes in physical and chemical traits of the soil especially in %sP,pH,%TNV,SAR,%sand,%silt, %clay and the information about qualitative and quantitative characters of the trees. According to the result of the research, they understood that there are distinctive differences among the percent of soil saturation (%sp), electric conduction (EC), clay percent (% clay), lime (%TNV) and SAR. In oil number 1, %sp (saturation percent ) and % clay are more and %TNV(lime), SAr, EC are less. In soil number 2, %sp (saturation percent ) and %clay are less and % TNV (Lime), SAR, EC are more.
