摘  要:
以地处毛乌素沙地东南缘的补连塔煤矿为研究对象,以沙柳为试材,采用野外观测手段,分析了风沙区的采煤塌陷在不同部位对沙柳根系的损伤,以期揭示风沙区采煤塌陷对植物根系的损伤机理。结果表明:在塌陷地随着坡度的增加,塌陷对根系的损伤越来越大。裂缝宽度、错位和裂缝与植物的距离是影响根系损伤程度的主要因素。在各个部位的裂缝中,对细小根系的损伤最大。

摘  要:
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 psammophilain 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.
