| 摘 要： | Based on long term and stationary research, the temporal and spatial patterns and dynamic laws of soil water content in Minqin desert area were studied. Some results are as follows:(1)The change of soil water content in different years is not obviously in shrub sand dune of Nitraria sibirica and Tamarix ramosissima, but it was great in shifting sand dune, the maximum is 2.538%; (2)The season dynamics can be divided into three stages: accumulating, consuming and stable; (3) The vertical change of soil water content distribution is obvious, i.e., decreasing with the depth; (4)Compared with the lower slope and middle slope,the upper slope has higher soil water content, the maximum is 15.408%.
