Transport characteristics of salt ions in soil columns planted with Tamarix chinensis under different groundwater levels.

ABSTRACT: The groundwater level is the main factor affecting the distribution of soil salinity and vegetation in the Yellow River Delta (YRD), China, but the response relationship between the spatial distribution of soil salt ions and the groundwater level in the soil-Tamarix chinensis system remains unclear. In order to investigate the patterns of soil salt ions responding to groundwater levels, in the 'groundwater-soil-T. chinensis' system. Soil columns planted with T. chinensis, a constructive species in the YRD, were taken as the study object, and six groundwater levels (0.3, 0.6, 0.9, 1.2, 1.5 and 1.8 m) were simulated under saline mineralization. The results demonstrated the following: As affected by groundwater, Na+ and Cl- were the main ions in the T. chinensis-planted soil column, with a tr
