氮沉降对生态环境的影响研究进展

Advances in the Effects of Nitrogen Deposition on Ecological Environment

氮沉降造成的氮饱和现象频率增多,引起的生态环境问题日益受到关注。对国内外氮沉降的类型及来源,氮沉降对植物、土壤动物、土壤理化性质及微生物的影响研究进行了全面论述,并探讨了氮沉降的生态环境影响研究存在的问题,展望了有关氮沉降的科学问题的研究趋势。

The nitrogen saturation phenomena caused by nitrogen deposition is becoming much frequently,and the environment deterioration caused by nitrogen deposition received more attention increasingly.In this paper the reasons and sources of nitrogen deposition,impacts of nitrogen deposition on plants,soil animals,edaphon,physical and chemistry characteristics of soil were comprehensively reviewed.Meanwhile,problems in the research of the effects of nitrogen deposition on ecological environment was discussed,and the future research developments about nitrogen deposition was proposed.
