| 摘 要： | 采煤塌陷致原始地形、地貌以及水资源的运移和转化等条件发生改变，使土壤侵蚀力度加大，原有稳定的土壤结构受到破坏，表土的理化性状和自身的营养条件发生改变，水肥沿倾斜的地面和地裂缝渗漏流失，降低了土壤持水能力和通气状况，造成水土流失。本文针对过去采煤塌陷对土壤性质影响研究的不足，提出今后研究工作应当注重采煤塌陷对土壤性质影响的集成研究，尤其要加强那些能源资源富集区沉陷区的研究，查明采煤塌陷区地形地貌和土壤理化性质的变异过程，揭示采煤塌陷所产生的土壤性质的变化程度和变化机理。

| Abstract: | Coalmining subsidence causes the changes of original terrain,land form and water resources,makes soil erosion more serious,destroys the original stable soil structure and changes the physicochemical properties of surface soil and the nutrient conditions.Water fertilizer leak and drain away along the sloping earth and land cracks,lower the water-holding capacity and aeration status of soil and leads to soil erosion.Aiming at the lack of research about the effect of coalmining subsidence on soil property,this... |
