我国采煤沉陷地土壤质量研究进展

Research Progress of Soil Quality in China Mining Subsidence Area

煤炭开采引起地表沉陷,使地表变形、坡度加大,土壤侵蚀加重,对土地资源造成了严重破坏,导致土壤质量下降。基于此,分析了采煤沉陷对土地破坏的特征,对有关采煤沉陷地土壤质量变化研究成果进行了综述,包括土壤物理性质变化、化学性质变化以及生物性质变化的研究,总结了其变化规律;探讨了采煤沉陷地土壤质量研究中的不足。最后综合目前研究的进展以及存在的问题,提出了今后采煤沉陷地土壤质量研究的重点和方向。

The coal mining activities would cause the subsidence to the surface ground.Thus the ground subsidence would cause the surface ground deformation,the slope increased,high soil erosion increased,the serious failure of the land resources and the soil quality reduced.The land failure features by the mining subsidence were analyzed.The paper had a statement of the study achievements on the soil quality variation of the mining subsidence land,including the study on the variations of the soil physical property,chemical property and biological property.The paper summarized the variation law and discussed the shortages of the study on the soil quality of the mining subsidence land.Finally,the paper summarized the present study progress and the existed problems and provided the focus and orientation for the further study on the soil quality of the mining subsidence land.
