chinois. 不合理的农田机械作业会造成土壤紧实度增加，这不仅会改变土壤的物理、化学和生物学性质，而且会使作物生长以及土壤生物活动受到影响，并增加温室气体排放，成为土地退化、作物产量降低及全球气候变暖的因素之一。本文综述近年来国内外在土壤机械压实方面的相关研究进展，探讨减轻土壤紧实度的可能方法和措施，为中国在农业现代化进程中合理使用农业机械，减少土壤机械压实提供参考。

Overuse of farm machinery in agricultural production results in soil compaction, which causes soil degradation, inhibits plant growth and the activities of the soil-borne organisms, and increases discharge of greenhouse gases into the atmosphere. The recent progresses of the international and domestic research on soil deterioration caused by agricultural machinery were summarized in this paper, in order to utilize the experiences of developed countries for reference to rational use of machinery in our modern agricultural production and to reduce soil degradation.
