土壤氮素生物地球化学循环的研究现状与进展

RESEARCH STATUS OF AND ADVANCES IN BIOGEOCHEMICAL CYCLING NITROGEN IN SOILS

氮素的生物地球化学循环不仅影响土壤生产力,还会引起全球环境变化,其过程主要包括氮素矿化、固氮、 氮素硝化和反硝化、铵离子的吸附和释放。文章全面综述了氮素生物地球化学过程研究的现状与进展及其可能存 在的问题。

Nitrogen biogeochemical cycling not only affects soil productivity, but also will cause global environment changes. Its main process includes nitrogen mineralization, nitrogen fixation, nitrification and denitrification, adsorption and release of ammonium. This text summarizes the current status of and advances in nitrogen biogeochemical cycling and the possible problems.
