酸性土壤中硝化作用的空间变异以及土壤本身对 NO3--N的吸附都是极具争议性话题。对酸性土壤中NO3--N吸附作用的研究不仅具有农学和环境双重意义，而且有助于我们进一步探讨酸性土壤中存在强烈硝化作用的可能性。本文综述了近年来国内外酸性土壤中NO3--N的吸附作用机理及其主要影响因素，结果表明NO3-是非专性吸附离子，其吸附主要受粘土矿物类型、pH、表面电荷、陪伴离子种类、电解质浓度以及有机酸有机质的影响。

Spatial variability of nitrification and adsorption of NO 3--N in acid soil are of controversial topics . The study on adsorption of NO3--N in acid soil not only has a double meaning for agriculture and environ-ment ,but also helps us to discuss the possibility of strong nitrification in acid soil .Adsorption mechanism and main influence factors of NO3--N have been reviewed in this paper ,the results show that NO3--N was nonspecific adsorption ,the adsorption mainly influenced by clay mineral type ,pH ,surface charge ,accom-panied ion species ,concentration of electrolyte and organic acid and organic matter .
