Based on the data from 66 plots including 35 samplings of aboveground biomass, the relationship between biodiversity and aboveground biomass was studied in the alpine meadow on Mt. Helan, China. The results indicated: Firstly, the aboveground biomasses were positively correlated with the average depths of soil layers for all sampling plots; secondly, the species richness and Shannon index were both negatively correlated with altitude, while other environmental factors, which could also affect the species richness or Shannon index, could only take effects on few community types; lastly, the response curves of specie richness or Shannon index to aboveground biomass were both unimodal.
