Survey on groundwater environment related to vegetation in Mu Us Desert.

[Objective] The research aimed to study the groundwater environment related vegetation in Mu Us Desert.[Method] Choosing the hinterland of Mu Us Desert,the relationship between vegetation and groundwater in desert areas was studied.The indicator system for the relationship between vegetation and groundwater in the sandy area was established,including vegetation population,vegetation cover,groundwater depth,vadose zone moisture content,groundwater mineralization and vadose zone salinity,as well as the corresponding field work methods.[Result] The results showed that the nine primary vegetation populations were distributed in the study area,and Artemisia,Salix and Carex were the dominant vegetation species.The groundwater mineralization in the sand dunes was 100-300 mg/L,and 800 mg/L in the beach.Vadose zone moisture content remained at 8%-16%.The dunes salinity was less than 0.2%,and beaches were higher than 0.3%.[Conclusion] These results provided a basis for study the relationship between vegetation and groundwater in Mu Us Desert.
