Abstract

Abstract:

In recent years, reactive nitrogen emissions have risen dramatically due to the rapid development of industrialization and agricultural intensification. Nitrogen deposition has become one of the critical driving factors of global change, which has a profound impact on forest ecosystems, especially the structure and diversity of soil microbial communities. Nitrogen deposition affects the structure and diversity of microbial communities directly or indirectly. In simulated atmospheric nitrogen deposition experiments, different nitrogen addition types and methods have varying effects on soil microbial communities. Furthermore, the interaction of nitrogen deposition with other environmental factors further complicates its effects on microbial communities. This paper synthesized the latest research progress on the effects of nitrogen deposition on soil microbial communities in temperate (including cold -temperate) forest ecosystems to enhance the understanding of the mechanisms of nitrogen deposition affecting soil microbes, and pay attention to the impacts of microbial community shifts on ecosystem functions, and provide scientific theoretical support for addressing the challenges posed by global climate change.

Key words: nitrogen addition types, nitrogen addition methods, interactions, soil microbes, forest ecosystems
