When we think about the deserts of the world, water abundance(资源丰富)is one of the last things that come to mind. But that might change for the Taklamakan Desert (塔克拉玛干沙漠) in China.
There is a huge underground sea that has more water than all of the great lakes in total in North America. "People have never dared to imagine so much water under the sand before, "said Professor Li Yan.
A basin is, a valley (山谷）that usually collects water from the mountain drainage systems(山脉排水系统), like water that has melted and is running down from nearby, snow-covered mountains. But, if you look at the Tarim (塔里木)basin, you won't see any water.
That's partly because local people collect most of the melt water to irrigate crops. The rest either seeps into the ground or evaporates into the dry desert air.
So how did this desert have such huge water? It dates back to (追溯到)2,000 years ago when farmers in the region began irrigating the land. And the soil of the local farmlands is salty, like the sea. "As a result, agricultural development over human history has enhanced the carbon sink," they write in their report.
They estimate(估计)that as much as 10 times the amount in all of the great lakes could be down there. The scientists don't advise locals to go digging for it, though, because it's extremely salty sea water.
