Abstract：The characteristics of soil salts in original habitat soil of Glycyrrhiza inflata Bat.were studied by means of field investigation and soil sample analysis.The results showed that soil salts in all layers of soil were generally high and salt accumulation at the surface layer was significant.The average value of total salts in surface soil(0-10 cm) was 32.08 g/kg,which indicated that the soils was highly salt-affected.Anions component of salts in soil were mainly Cl-,SO2+4,HCO-3.Cations component of salts were mainly Ca2+,Na+,Mg2+,but there was no CO2-3.There were four soil salts factors,including Ca2+,Cl-,SO2-4,Na+.Therefore,the salt-affected soils belonged to sulfate-chloride type.The bicarbonate was a subordinate constituent of salt-affected soils.The Ca2+ was abundance in the whole vertical section,so this soil belonged to the typical calcic soil.
