大气的干湿沉降及其对海洋生态系统的影响

Wet and dry deposition and its influences on marine ecosystem

对国内外学者近些年来在大气干、湿沉降研究方面的工作作了较为系统的综述：包括于湿沉降的采样方法、研究方法、主要结论。重点讨论了大气沉降对海洋生态系统的影响，特别是与河流输送量的对比，指出：大气干湿沉降对某些海区的初级生产较之河流而言有不可忽视的作用，氮的输送以湿沉降为主，而磷的输送尚待进一步研究。最后提出了大气干湿沉降今后可能的若干重要研究方面。

Based on the studies in recent years, this paper summarizes the research results of at-mospheric dry and wet deposition, including the sampling nriethod, research methods and main re-sults. The influences of atmospheric dry and wet deposition on marine ecosystem were discussedin detail, especially the comparison with river input. It was shown that the atmospheric dry andwet deposition have quite important influences on primary production, with respect to the riverinput. Most nitrogen which input to ocean by atmospheric deposition comes from wet deposition.But for phosphorus, it needs to be investigated further. At last, several propable interesting topicswere proposed.
