【摘要】：在矿区开采和复垦过程中大型机械的使用产生了土壤压实,并严重扰动了土壤内部结构,导致土壤孔隙数量减少,连通性和渗水能力下降,土壤孔隙作为土壤水气交换的重要场所决定着土壤水分和空气状况,进而影响复垦土壤质量与肥力。为探究矿区机械压实作用对土壤孔隙的影响,系统梳理了矿区机械压实作用下土壤孔隙的获取和表征方法,对农业机械压实相关研究进行了简单归纳,在此基础之上阐述了矿区机械压实对土壤孔隙影响的研究进展,总结了当前研究存在的问题,并提出今后在探究矿区机械压实对土壤孔隙特性影响时应创新压实土壤孔隙的定量表征方法,重视机械压实对土壤孔隙特性影响机理的考究,以期为改善矿区土地复垦效果提供理论指导。
[Abstract]:In the mining and reclamation process, the use of large-scale machinery produced soil compaction, and seriously disturbed the internal structure of the soil, resulting in the reduction of soil porosity, connectivity and water permeability. Soil porosity, as an important place for soil moisture and air exchange, determines soil moisture and air conditions, and then affects the quality and fertility of reclaimed soil, in order to explore the effect of mechanical compaction on soil porosity in mining area. The methods of obtaining and characterizing soil pores under the action of mechanical compaction in mining area were systematically combed, and the related studies on compaction of agricultural machinery were summarized briefly. On this basis, the research progress on the effect of mechanical compaction on soil porosity in mining area is described, and the problems existing in the current research are summarized. It is suggested that the quantitative characterization of compacted soil porosity should be innovated when exploring the effect of mechanical compaction on soil pore characteristics in the future, and the mechanism of mechanical compaction on soil pore characteristics should be emphasized. In order to improve the effect of land reclamation in mining areas to provide theoretical guidance.
