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。
The use of large machinery during mining and reclamation has resulted in soil compaction and severe disturbances in the soil’s internal structure, leading to a reduction in the number of soil pores, connectivity and water seepage ability, and the determination of soil porosity as an important site for soil moisture exchange Soil moisture and air conditions, thereby affecting the quality of reclaimed soil and fertility. In order to explore the influence of mechanical compaction on soil porosity in the mining area, the methods of obtaining and characterizing soil pores under mechanical compaction in the mining area were systematically summarized, and the related researches on compaction of agricultural machinery were briefly summarized. Based on this, Mechanical compaction on the impact of soil porosity, summarize the existing problems in the study, and put forward in the future to explore the impact of mechanical compaction on the soil pore characteristics of the soil should be innovative quantitative compaction of soil pore characterization methods, emphasis on mechanical compaction The research on the mechanism of soil pore characteristics has aroused great interest in the future. It is hoped to provide theoretical guidance for improving the land reclamation effect in the mining area.
