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 div-ersity and productivity in the study area,while maintaining the integrity of the regional environment could improve effectively the relevance between species diversity and productivity.
