摘要
森林在生态系统中有大自然氧吧和维持生态平衡的意义,通过查阅国内外有关于氮沉降的文献,从氮沉降对森林植物、动物和微生物的影响等方面和角度综述氮沉降对森林生态系统的影响,介绍了相应的响应机制,并对今后的进一步研究工作提出展望。氮沉降的研究还存在一些问题,如目前国际上对氮沉降研究方法还没有形成一套比较完备的标准体系,世界各地氮沉降量测定的研究方法和仪器设备都不相同,导致研究结果会出现差异,所以对真实生态情况很难进行统一的定论和科学的比较分析。相比国外研究而言,国内研究虽然形成了比较规范的监测网,但研究的技术手段缺乏确凿性和一致性,并且研究对象不全面,树种选择局限,对阔叶树种研究较少。
Forests have a natural oxygen bar in the ecosystem and the significance of maintaining ecological balance.By consulting domestic and foreign literature on nitrogen deposition,this paper summarized the impact of nitrogen deposition on forest ecosystems from the aspects and perspectives of the effect of nitrogen deposition on forest plants,animals and microorganisms,introduced the corresponding response mechanism,and proposed prospects for future research work.There were still some problems in the research of nitrogen deposition.For example,the international research methods for nitrogen deposition had not yet formed a relatively complete standard system,and the research methods and equipment for the determination of nitrogen deposition were different around the world,leading to differences in research results.Therefore,it is difficult to make a unified conclusion and scientific comparative analysis of the real ecological situation.
