Nitrogen deposition and climate warming can alter soil bacterial communities. However, the response of bacteria in an alpine steppe to these changes is largely unknown. In this study, a field experiment was performed on northeastern Qinghai-Tibetan Plateau determine communities steppes nitrogen application warming. The consisted four treatments, namely no-N with no-warming (CK), N (8 kg ha −1 year ) (N), (W), (W&N). This study aimed investigate (1) diversity community structure under simulated conditions, (2) key environmental factors responsible for changes. Based results, composition did not change significantly short term. Warming had significant effect overall composition, rare species individual taxa. Besides, interaction between β-diversity. Above-ground plant variables were highly correlated characteristics. distribution range community. Overall, suggests that remain relatively stable at level short-term climatic may have no impacts
