Abstract

Along an elevation gradient(3200 m to 3800 m) on Qinghai-Tibetan plateau, BIOLOG GN2 plates were used to analyze the elevation patterns of bacterial community functional diversity. The redundancy analysis (RDA) method was further used to analyze the relationship between bacterial profiles and the environmental variables. The results indicate that soil variables explain 46.6% of the variation in bacterial community functional diversity. Among the soil variables, soil available phosphorus explains the largest part, which suggests that it might be an important limiting factor for soil bacterial community functional diversity in this area. The soil temperature, which changes with the altitute, also has a profound effect on bacterial community functional diversity.

Key words： alpine meadow; BIOLOG; RDA; elevation; available phosphorus
