Abstract: The relationship between biodiversity and ecosystem functioning is a hot subject in ecological and environmental sciences.Focused on this issue,the research history and the different academic viewpoints during the last two decades were reviewed systematically.The current knowledge and development of the theoretial and experimental work were shown fully.The future trends and challenges were also prospected.Theoretical and experimental studies indicated that biodiversity tends to be correlated positively with ecosystem functioning (stability).But diversity is not the direct driver of this relationship.Ecosystem functioning (stability) potentially depends on the interaction strength among species,the difference of functional response of species,the types and scales of ecosystems etc.In the study of biodiversity and ecosystem functioning,the important problem is not merely conclusion,but also mechanism hidden behind.
