Abstract:: Meadow wetland was prone to salt accumulation in arid area.In this study,the method of field experiment and laboratory experiment were used to find out the main component of salt in the meadow wetland of Yinchuan plain,and to provide scientific guidance for the restoration of wetland.The results showed that soil salinity factors indicated that soil salinity,pH and most of salt ions appeared to be significant or very significant positive or negative correlation.There was a significant or very significant correlation between Na+,Cl- and most of the ions.All the main components analysis of salt ions showed that,in 0-30 cm,Na+,Cl-,HCO3-+CO32- were main salt ions in the study area; in 30-100 cm,Na+,Ca2+,Cl- were main the salt ions of salt accumulation in the study area.Therefore,Na+ and Cl- were the main salt ions in the Yinchuan plain,which should focus on the two kinds of ions.
