Influence of growing season rainfall amount and clipping intensity on aboveground net primary productivity in leymus chinensis steppe

摘要：

Aboveground net primary productivity ( ANPP) is the foundation to assess structure and function of grassland ecosystem.The amount of rainfall is dominant climatic driver and clipping times (or grazing intensity) is important external perturbation to the variability of ANPP in the leymus chinensis steppe of China, However therere many different opinions on the relationship (Cai et al.,2005 ;Bai et al.,2004).The objective of this study was to evaluate the adaptable clipping intensity under potential changes in rainfall.
