【摘要】：在礦區(qū)開采和復(fù)墾過程中大型機械的使用產(chǎn)生了土壤壓實,并嚴重擾動了土壤內(nèi)部結(jié)構(gòu),導致土壤孔隙數(shù)量減少,連通性和滲水能力下降,土壤孔隙作為土壤水氣交換的重要場所決定著土壤水分和空氣狀況,進而影響復(fù)墾土壤質(zhì)量與肥力。為探究礦區(qū)機械壓實作用對土壤孔隙的影響,系統(tǒng)梳理了礦區(qū)機械壓實作用下土壤孔隙的獲取和表征方法,對農(nóng)業(yè)機械壓實相關(guān)研究進行了簡單歸納,在此基礎(chǔ)之上闡述了礦區(qū)機械壓實對土壤孔隙影響的研究進展,總結(jié)了當前研究存在的問題,并提出今后在探究礦區(qū)機械壓實對土壤孔隙特性影響時應(yīng)創(chuàng)新壓實土壤孔隙的定量表征方法,重視機械壓實對土壤孔隙特性影響機理的考究,以期為改善礦區(qū)土地復(fù)墾效果提供理論指導。
[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.
