摘要
下行效应和上行效应对植物群落动态变化有着重要的影响.回顾了下行和上行效应的发展史及主要理论,综述下行和上行效应对草地植物群落的生产力和植物多样性的影响和作用机制.指出下行和上行效应研究的不足,提出下行和上行效应的研究展望.
Top-down and bottom-up effects exert important impacts on plant community dynamics.This paper reviewed the development history and main theories of top-down and bottom-up effects,and attempted to summarize the mechanisms and effects of top-down and bottom-up effects on grassland plant communities from the perspective of productivity and plant diversity.Finally,related research deficiencies were pointed out and the research prospect put forward of top-down(herbivores) and bottom-up(resource nutrients) effects on plant communities.
