摘要: 森林土壤氮素转化与循环在森林生态系统功能中占有极其重要的意义。本文综述了森林土壤氮素转化与循环的研究历程和现状;介绍了凋落物的归还、施肥、大气沉降、自生固氮、氨化、硝化、反硝化、植物吸收、NH3的挥发、NO3-淋溶等土壤氮素输入、转化和输出的途径和过程;最后从研究目标、研究方法、研究对象和研究内容4个方面归纳了森林土壤氮素转化与循环的发展趋势。

Abstract: Nitrogen transformation and cycling in forest soils are of signification importance to the function of forest ecosystems.In this paper,the research history and status were summarized.The processes of soil nitrogen input,interior transformation and output,including litter return,fertilization,atmosphere desposition,ammonification nitrogen fixation,ammonification,nitrification,denitrification,plant uptake,NH3 volatilization and NO3- leaching,were introduced.Finally,the tendency of study on soil nitrogen transformtion and cycling was concluded according to research methods,objects,objectives and contents.

Key words: Urban Forest, Structure and benefits, CITYgreen Model
