Abstract

Salt domes have high impact on groundwater, mineral matters and the Soil quality of lowland regions due to intrusion into the saline mass and going up to surface of earth. In this process, a remarkable rate of salt going up to surface of earth and entered to lowland regions by the way of various erosional factors and effect on the Soil quality. This research aims to investigate the impact of Salty dome of Korsia on the Soil quality of lowland regions. For this, research region is divided into four sub-regions with regarding to their land uses and distance from salt dome and 22 samples were collected from the region. Ions of Mg, N, K, Na, Ca as well as volume of pH and EC and soil texture of samples of year of 2010 was measured and while the variables of year of 1993 such as Na, Ca, SAR, EC, pH were prepared from Ministry of Agriculture. The significant differences between the various land uses and the change rates of this elements in the land uses during two periods of time were caused to identifying of effective component in the Soil quality and classifying of chemical elements was determined by land uses using Multivariate statistical methods such as variance analysis, independent T test, factor analysis and cluster analysis, respectively. The results indicated that all variables excepts K, Mn, pH, clay and chemical parameters such as pH and N have significant differences during period of time 1993-2010 according to their land uses; and with regarding to increasing of pH of soil in the periods of time of 1993-2010 in the agriculture land uses and existing of alkaline soils, the effect of salt dome on the Soil quality of lowland is clear. The results of factor analysis introduced six components such as Ca, SAR, Na, EC, N and K as the effective variables in the controlling of Soil quality of lowlands. The results of cluster analysis showed that the clustering of samples in three clusters is consistent with the land use classification.
