英文摘要In order to understand the response of soil microbial biomass to warming, field warming experiments using open top chambers (OTCs) were conducted in three alpine meadow sites on the Northern Tibetan Plateau since May 2010. Soil samples for microbial biomass carbon (MBC) and nitrogen (MBN) measurements were collected in July, August and September 2011. Generally, experimental warming had no obvious effect on MBC. MBN and MBC/MBN ratio across the three sampling dates. However, experimental warming tended to decrease MBC and MBN but increase MBC/MBN ratio. The negative effect of experimental warming on microbial biomass may be related to warming-induced decline in soil water content. Our findings suggested that short-term experimental warming may have no obvious effect on microbial biomass for the alpine meadow on the Tibetan Plateau. (c) 2012 Elsevier B.V. All rights reserved.
