摘要
In order to reveal the moisture content in sand layers,the forms of the moisture, the moisture migration and equilibrium in the Tengger desert, the authors study the moisture content of different sand dunes in the southeastern part of Tengger Desert. The results show that the spatial variation of moisture content of sand layers in Tengger Desert is very great, and the upper part of sand dunes have low moisture content, while the lower part of sand dunes and the low-lying land have high moisture content. Capillary water layer indicates the height of capillary water is about 60 cm and the average moisture content of capillary water is 14.9%.
