氮沉降增加对森林植物影响的研究进展

Research of Impacts on Forestry by Nitrogen Deposition

由于化石燃料的燃烧、含氮化肥的使用以及畜牧业等人类活动的影响,向大气中排放的含氮化合物数量不断上升,从而引起大气氮沉降的增加,使得生态系统发生了一系列变化。为了更好地研究氮沉降这一环境变化,从植物生长、植物抗逆性、植物营养、凋落物分解、以及外来植物入侵等方面对氮沉降进行了综述。

The chemical compound containing nitrogen from burning of fossil flue and fertilizer and human being＇s activities is increasing in resent years, which leads to growing nitrogen deposition from the air and to have changed the ecological system. The summaries on nitrogen deposition are displayed from the aspects including plant growth and phytotrophy and plant tress resistance and litter decomposition and the invasion of non - native plants.
