Abstract

Assessing the status of a regional salinity is considered as an important step in LAND MANAGEMENT. This study was performed on part of Turkmen Sahra Lands in Golestan Province with Aridic soil moisture regime, in order to evaluation of salinity changes during the years of 1355, 1368 and 1392. For this purpose, two geostatic methods (ordinary kriging and cokriging) and four algebra methods (Inverse distance weight, Radial basis function, Global polynomial INTERPOLATION and local polynomial INTERPOLATION) were used for estimating the amount of salinity in depths of 0-50, 100-50 and 150-100 cm. The results showed the percent of land with more salinity than 32 dS/m has increased from 8.95 percent in 1976 to 45.22 percent in 2013. It seems during the 37- year management period, the improper utilization and collection from water and soil resources have led to increase in salinity of the soil. Therefore, so it is suggested to use various methods and appropriate management proceedings to monitor and control the process of increase soil salinity in the region.
