Abstract: Elevated temperature and atmospheric nitrogen deposition are two important scenarios of global climate change, which will lead to changes in plant species diversity and soil microbial diversity. For plant species diversity, the increase in climate warming and atmospheric nitrogen deposition has a direct effect on its impact (by altering plant phenology, affecting plant distribution and community composition) and indirect effect (by influencing plant growth and soil physical and chemical nature). For soil microbial diversity, climate warming and atmospheric nitrogen deposition mainly change the microbial soil environment, microbial species and quantity, directly or indirectly affect its diversity. In addition, plant species diversity and microbial diversity are associated with global warming and nitrogen deposition, and global warming and nitrogen deposition affect soil microbial diversity by altering plant species diversity and will also react to plant species through interspecific relationship. Based on the influence of climate change on habitat environment, this paper selected two indexes of temperature and atmospheric nitrogen deposition to explore the relationship between plant species diversity and soil microbial diversity to climate change, and analyzed the relationship between plant species diversity and soil microbial diversity, which can provide a reference for plant and microbial diversity protection.
