Abstract In this study, 71 water samples were collected from Badain Jaran Desert, which included 8 springs, 12 wells and 51 lakes. The spatial distribution patterns of chemical parameters and total dissolved solids (TDS) of lakes during the past 10 years were analyzed. Result shows that total dissolved solids of lakes gradually decrease from northwest to southeast. Affected by weather conditions and local environments the hydrogeochemical type of lakes turns from Na-Cl-CO3-(SO4) into Na-CO3-Cl-(SO4). The lakes that lie in the southeast Badain Jaran Desert have low TDS and the content of SO2-4 is more than CO2-3 for a large recharge of fresh water resource. The TDS of groundwater are different from surface water, and there is no clear linear correlation between them.
