水资源在流域水循环过程中形成和转化，以河流为纽带把山地、盆地平原、绿洲和荒漠系统联系起来。
In the water circulating process, the mountains, basins, plains, oases and deserts are connected due to the formation and conversion of the water resources through the streams.
由于荒漠盆地平原系统不产生径流，因此，地表水、浅层地下水和泉水、湖泊都必然地以相邻的山地系统为供给水源地。
The adjacent mountain systems are the water source areas of all the streams, shallow groundwater, springs, and lakes because runoff does not occur in the desert basin and plain systems.
