英文摘要

Trace element transfer model was performed to estimate salt loading in soil on 1500-hectare study area located on Kesikkopru Basin of Central Anatolia Region in Turkey. The model was run for 43 sampling locations, which are selected from different crop patterns and different soil types. The predicted and measured salt loads in soil were compared at the end of the study period. The soil salinity observation data and model estimation results in different depths were prepared as a geodatabase lobe integrated into ArGIS. The salinity map was produced by ordinary kriging interpolation method. According to statistical evaluations, model showed acceptable prediction for soil salinity with the coefficient of determination (R-2) values (0.75 to 0.88) and modeling efficiency (E) values (0.58 to 0.72). Also, the model was run for the next 10 years to simulate soil salinity changes in the future. The results show that salinity will be a potential risk for the basin in the future. The salinity projection in soil for 2014 was estimated with leaching and without leaching fractions. While the salinity in soil profile varied between 8 and 12 dS m(-1) without leaching, the salinity amount reduced drastically to 0-6 dS m(-1) with leaching applications.
