Abstract

Research on the spatio?鄄temporal variation law of soil water content in a subsidence area，especially in a semi?鄄arid mining area，was conducted to help reestablish a sound ecological system. In this study，water loss in sandy soils of the Bulanta coal mining area in the southeast part of the Mu Us Desert was analyzed and discussed using a spatial contrast method and correlation analysis in 2005 and 2006. One sand dune without mining was the control，and the others subsided respectively in March of 2005 and July of 2004. Results showed that the degree of soil collapse was significantly and negatively correlated （r=－0.73，P＜0.05） to the water content of sand dunes. For 0 - 100 cm depths，during both the rainy and drought seasons，1） water content of non-collapsed dunes was significantly greater （P＜0.01） than collapsed dunes；2） at different depths，water content in non-collapsed dunes was significantly greater （P＜0.01） than corresponding depths in collapsed dunes，except of 60 - 100 cm depths；and 3） except for the top of 2004 year collapsing dune，for different locations，water content of non-collapsed dunes was significantly greater （P＜0.05） than corresponding locations of collapsed dunes. ［Ch，3 fig. 2 tab. 13 ref.］
