Abstract: Fresh water resources are lack in lake salt,oil and natural gas chemical base in central Qaidam Basin.water supply problem is very serious,which becomes a development bottleneck of lake salt,oil and gas and other mineral resources.Based on the existing exploration data analysis,we pointed out that there is abundant light flow water in shallow salt lake brine distribution region in large river basin downstream and deep ancient river channels,which has a good prospect of development and can solve the water conflictin lake salt,oil and natural gas industry base in circular economy of Qaidam Basin.
