摘　　要：本文通过对安徽省某山坡林地土壤、某农田土壤的有机质含量、pH值的测定分析,探讨了土壤有机质含量的分布规律,以及土壤pH值的变化规律,并初步研究了土壤有机质含量与土壤酸碱性之间的相互关系。结果表明:土壤有机质含量和土壤pH值具有明显的剖面分异,其表层土壤有机质含量显著高于底层土壤,且表层土壤pH值基本高于底层土壤;而山地不同部位的土壤有机质含量也有明显差别,可能与土壤侵蚀强弱有关;山坡林地土壤有机质含量明显高于农田土壤,但pH值则明显低于农田土壤。In this paper, through the determination and analysis of soil organic matter and pH value of a hillside woodland soil and a farmland soil in Anhui Province, the distribution law of soil organic matter content and the change law of soil pH value were discussed,and the relationship between soil organic matter content and soil acidity and alkalinity was preliminarily studied.The results showed: soil organic matter content and soil pH value had obvious profile differences, the soil organic matter content in the topsoil was significantly higher than that in the bottom soil, and the pH value in the topsoil was generally higher than that in the bottom soil;the content of soil organic matter in different parts of mountain has obvious difference, which may be related to soil erosion;the soil organic matter content was significantly higher than that offarmland soil, but the pH value was significantly lower than that offarmland soil.

关 键 词：土壤有机质 土壤PH值 山林地土壤 农田土壤
