Abstract
Salt domes have high impact on the ground waters, mineral matters and their soil quality of lowland regions due to penetrating of them in to the saline mass and going up to surface of earth. In this process, 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 divided in four regions with regarding to their land uses and their distance from salt dome and 22 samples was gathered from these regions. Ions of Mg, N, K, Na, Ca and as well as volume of PH and EC and soil texture of samples of 2010 was measured and variables of 1993 such as Na, Ca, SAR, EC, pH was purchased from ministry of agriculture and significant differences in the various land uses, change rates of this elements in the land uses during in two periods of time, identifying of effective component in the soil quality and classifying of chemical elements was determined by land uses using multivariate statistical techniques such as variance analysis, independent T test, factor analysis and cluster analysis respectively. Results showed that all variables excepts K, Mn, pH.
