森林生态系统的氮循环及其调控机制

DISSERTATION ON NITROGEN CYCLE AND ITS RECULATION MECHANISM OF FOREST ECOLOGICAL SYSTEM

本文从生态系统水平,论述了氮素在森林生态系统中的分布和循环,讨论了森林生态系统中氮的输入、吸收、存留、归还及输出等过程中的显著特点,并从生态平衡的观点对森林生态系统氮循环的调控机制作了初步探讨。

This paper presents the distribution and cycle of Nitrogen in forest ecological System, and discusses the characteristics of input,absorption, reservation,reuersion and output processes of nitrogen. It also inquires preliminarily into the reculating mechanism of nitrogen cycle.
