Study on the Relationship between Exploitation of Soil and Water Resources and Redistribution of Salt in Inland Arid Plain Area

摘要

By investigating the soil salt content and groundwater quality of typical profiles of soil and water development regions in Fukang City and Hami City of Xinjiang Uygur Autonomous Region, this study analyzed the redistribution characteristics of salt content in soil and groundwater under the conditions with or without horizontal drainage in the initial stage of reclamation. The results showed that many soil salts accumulated in the reclamation area could be discharged from the farmland under horizontal drainage conditions in the initial stages of reclamation, so the salt contents of soil and groundwater below the cultivated horizon were low; but in reclamation areas with shaft well drainage instead of horizontal drainage in the initial stages of reclamation, the salt in the surface stratum leached into the soil and groundwater below the cultivated horizon due to the descent of the groundwater level.
