土壤中有机碳和氮素的变化过程研究概况

从土壤有机碳与土壤性质的关系、土壤有机碳的分布、土壤氮素形态、氮素的转化和土壤氮素分布5个方面综述了国内外对土壤有机碳、氮素的变化过程研究概况,指出土壤有机碳和氮素的变化反映了土壤形成过程中有机物质的转化和土壤肥力特性,直接影响着温室气体的组成。

This study reviewed the changes of soil organic carbon and nitrogen from five aspects： relationship between soil organic carbon and the character of soil, distribution of soil organic carbon, forms of soil nitrogen, changes of soil nitrogen as well as distribution of soil nitrogen. It was pointed that the characters of organic substances transformation and soil fertility were reflected by the change of organic carbon and nitrogen in soil, and the change influenced the buildup of greenhouse directly.
