Abstract

Abstract: Responses of the stipa glareosa community species diversity and above-ground biomass to precipitation variation was examined by an in situ experimental platform in desert-grassland region in northern China. The results indicated that plant species changed with precipitation variation and the four kinds of species diversity index in June were higher than that in August. The Shannon-Wiener index, Simpson index and Patrick index were the lowest while rainfall decreased by 40%. Pielou index was at the lowest while rainfall decreased by 20%. Precipitation change also impacted the community coverage and biomass. The coverage in June was higher than that in August while rainfall decreased by 60%, 40% and 20% and lower than that in August while rainfall increased 20%, 40% and 60%. Precipitation change had a cumulative effect on vegetation coverage in the desert-grassland. Standing biomass increased with precipitation increase, and till the highest when precipitation increased by 60%. Litter biomass significantly reduced with precipitation increased 20%, 40% and 60% or decreased 20% (P<0.05). The critical precipitation range for plant community above-ground biomass and species diversity was 40%-20% decreased and 40%-60% increased, and precipitation increase by 20%-40% had no significant effects on the above-ground biomass and species diversity.

Key words: desert grassland, species diversity, biomass, precipitation increase or decrease
