Relationship between species diversity and productivity in four types of alpine meadow plant communities

Abstract

Abstract: The relationship between species diversity and ecosystem function is one of the core problems on biodiversity research.Productivity is an important modality of ecosystem function.The species diversity of natural communities is often strongly related to their productivity.The grassland is an important component of the terrestrial ecosystems and plays a significant role in the biodiversity and ecosystem function's study.The relationship between species diversity and productivity of natural communities were studied on four alpine meadow types.The results showed that the species diversity-productivity pattern was linearly increase in Kobresia pygmaca meadow,K.humlis meadow,Potentilla froticosa shrub,while there was no significant linear relationship in K.tibetica of swamp meadow,which indicated that the species diversity of natural community could influence the productivity.At the same time,different environmental resource and environmental heterogeneity contributes to the productivity as well,which form discrepant structural characteristics of community and distribution of species diversity.
