摘　　要：在对青海湖高寒湿地进行群落调查的基础上,研究了在群落梯度上高寒湿地的生物多样性与生产力的关系,并探讨了在同一区域内环境的整体性对高寒湿地的生物多样性与生产力关系的影响。运用SPSS软件进行曲线拟合,研究了青海湖内陆高寒湿地物种多样性和地上生物量的关系。研究结果表明,(1)无论是在群落尺度上还是在区域尺度上物种多样性指数与地上生物量呈显著的负相关。(2)在研究区内区域因素对物种多样性和生产力的影响较弱,但如果保持区域环境的整体性则可以有效地提高物种多样性和生产力的相关程度。The relationship between biological diversity and productivity of alpine in regard to community structure wetland was investigated on the inland alpine wetlands of Qinghai Lake based on community survey.The influence of environmental integrity on the relationship was addressed in the area.Species diversity was regressed biomass using the SPSS fit curve function.The results show that（1） species diversity and biomass have a significantly negative correlation at both community and regional scales,and（2） regional factors had little effect on the species diversity and productivity in the study area,while maintaining the integrity of the regional environment could improve effectively the relevance between species diversity and productivity.
