Abstract:: With Bulianta coal located in Muus Desert in the southeast margin as research object,taking Salix psammophila?as test material,the damage on roots of Salix psammophila?in sand mining subsidence areas were analyzed through field observation methods,in order to reveal plant roots damage mechanism in sandy area by mining subsidence.The results showed that with subsidence slope increasing,the root damaged more serious.Crack width,dislocation and distance between plant roots and crack were main factors affecting root damage.In various parts of the cracks,the damages to the tiny roots were the strongest.
