摘　　要：高寒草甸是高山生态系统的主要组成部分,其特有的条件孕育了丰富的野生花卉资源。本文在综述有关高寒草甸生物群落多样性与生物量的研究成果的基础上,着重分析了生物多样性与海拔变化的关系、地上生物量及地下生物量与海拔变化的关系,以及多样性与生物量的关系,提出对于生物多样性与生物量海拔梯度的变化特征的研究应结合中国特有的三级阶梯和研究区域具体的地质土壤条件进行研究和归纳,为今后各地高山观赏花卉在本土景观营造、生态廊道建立提供可靠的依据,为未来野生花卉的应用与发展提供基础资料。The alpine meadow is the main part component of the mountain ecosystem,giving birth to a rich flower resource.Based on research results of the biomass and biological diversity of the alpine meadow,this paper deals with the relation of biodiversity to the elevation changes,the relation of the biomass to the elevation changes,and the relationship between biomass and diversity.These variation characteristics should be combined with regional specific geological soil conditions for the future research.The purpose of investigation of the diversity and biomass is to provide a basic information for the future local landscape establishment,ecological corridor building and application and development of wild flowers and plants.
