Precipitation and aridity index regulating spatial patterns of vegetation production and species diversity based on alpine grassland transect, Tibetan Plateau
31 Although the relationship between the aboveground net primary production (ANPP) and species 32 diversity (SR) have been widely reported, there is considerable disagreement about the fitting 33 patterns of SR–ANPP, which has been variously described as ‘positive’, ‘negative’, ‘unimodal’, 34 ‘U-shaped’ and so on. Not surprisingly, the effect-factors including precipitation, aridity index and 3...
متن کاملAridity Index in Songnen Grassland, Northeast
Reference evapotranspiration (ET0) plays an irreplaceable role in regional dry/wet 15 conditions under the background of climate change. Based on the FAO Penman-Monteith method 16 and daily climate variables, ET0 was calculated for 22 stations in and around Songnen Grassland, 17 northeast China, during 1960-2014. The temporal and spatial variations of ET0 and precipitation (P) 18 were comprehen...
متن کاملVariation of soil hydraulic properties with alpine grassland degradation in the Eastern Tibetan Plateau
Ecosystems in alpine mountainous regions are usually more vulnerable and easily be disturbed by environmental change globally. Alpine swamp meadow, a unique grassland type in the eastern Tibetan Plateau which provides important ecosystem services to the upstream and downstream regions of international rivers of Asia even the world, is undergoing severe degradation, which can dramatically alter ...
متن کاملEcosystem Carbon Storage in Alpine Grassland on the Qinghai Plateau
The alpine grassland ecosystem can sequester a large quantity of carbon, yet its significance remains controversial owing to large uncertainties in the relative contributions of climate factors and grazing intensity. In this study we surveyed 115 sites to measure ecosystem carbon storage (both biomass and soil) in alpine grassland over the Qinghai Plateau during the peak growing season in 2011 ...
متن کاملComparison of Soil Microbial Biomass and Enzyme Activities among Three Alpine Grassland Types in Northern Tibet
Soil microbial biomass and enzyme activities have an important influence on nutrient cycling. The temporal variation in soil microbial biomass C, N, and enzyme activities during the growing season were determined under three different alpine grasslands in Northern Tibet. The results showed that soil microbial biomass C, and N contents and enzyme activities of the alpine meadow (AM) and the alpi...
