Increasing nitrogen deposition and grassland productivity in Mongolia

摘要：

Introduction The amount of nitrogen (N) fall-down from the atmosphere to the biosphere ( nitrogen deposition) is increasing globally due to increased fossil fuel consumption and chemical fertilizer application (Galloway et al.,2004).As N is essential for plant growth,increased N deposition affects plant primary productivity ( Vitousek et al.,1997 ).However,increased N deposition can also decrease plant diversity (Stevens et al.,2004).
