Annual rainfall ranges from zero to 150 mm in the desert, and from 150 to 300 mm in the semi-desert areas (Rode, 1955). The region comprises the extremely arid great deserts of Central Asia, includ­ ing the Aral-Caspian Depression - an immense lowland, barren, cold desert - the Takla Maklan desert of Sinkiang, and the Gobi Desert of Mongolia (Fig. 4). These are deserts of drifting sand, with cold winters, and very hot summers having scanty precipitation. Only two great rivers traverse the central Asian deserts: the Syr-Darya, the waters of which are used for irrigation in Uzbekistan, and the Amu-Darya, which is used for watering land in Turkmenistan (Manton, 1954).
