英文摘要	In this study, HYDRUS-1D model was coupled with geographic information system (GIS) for evaluating the effects of climate changes on soil salinization. The coupled HYDRUS-1D-GIS system was applied in a coastal region (Gabes Oasis) for evaluating the effects of various climate change scenarios on temporal change in soil electrical conductivity (EC) and for developing irrigation practice that desalinates soils. The climate change scenarios were selected based on the climate change projections by 2050 and increased irrigation water allocations. There were three main findings. First, HYDRUS-1D and GIS were successfully coupled and used to perform simulation with consideration of the large differences in soil texture in the studied oasis. Second, for all climate change scenarios, spatial extent of EC for 2050 is projected to reach levels (> 4 dS m(-1)) corresponding with being classified as saline soils. Third, with climate changing as simulated, it is recommended to increase irrigation water application with 20% or more than today to avoid further increases in soil EC. Overall, this study can be used as a guide to implement the most appropriate strategy of soil and water management.
