| Abstract: | Driven by both nature and human function, the biogeochemical course of nitrogen on earth surface and its environmental effect has become a significant content of regional research in current global change .In this article we discuss the every course in nitrogen cycle and its quantity feature, then introduce the models of nitrogen cycle, we also carry out a brief exposition for the hot-spot of the research of nitrogen cycle in current ecological system. |
