摘要
土壤酸化是指土壤接受一定数量交换性氢离子或铝离子,使其中碱性(盐基)离子淋失的过程。目前我国耕地土壤酸化程度呈上升趋势,尤其是南方地区,土壤酸化形势严峻。基于此,介绍了土壤酸化的危害,分析了我国土壤酸化的成因,并对土壤酸化提出了预防控制措施。
Soil acidification refers to the process of soil receiving a certain amount of exchangeable hydrogen ion or aluminum ion which leads to the leach- ing loss of its alkali （base） ion. In China, soil acidification of farmland shows an increasing trend, especially in south Chi- na. In this study, hazards of soil acidifi- cation were introduced, causes analyzed, prevention and control measures pro- posed.
