摘　　要：开展咸盐湖泊微生物调控碳氮循环机理及其对盐度的响应研究,对于理解全球碳氮循环具有重要的科学意义.针对与咸盐湖泊碳氮循环相关的前沿科学问题,围绕“有机质输入增加”、“温度增高”与“盐度降低”等气候环境条件变化对咸盐湖泊碳氮循环微生物作用的影响机理与环境效应开展了综合研究,取得了系列研究发现.最后对湖泊碳氮循环微生物作用提出总结,并对未来发展方向提出展望.Exploring the mechanisms of microbial regulation of carbon and nitrogen cycling in saline lakes and their response to salinity is of great scientific importance for understanding the global carbon and nitrogen cycles.In response to cuttingedge scientific questions related to the carbon and nitrogen cycle in saline lakes,the authors conducted a comprehensive study on the impact mechanism and environmental effects of climate and environmental changes such as increased organic matter input,increased temperature,and reduced salinity on the microbial activity of the carbon and nitrogen cycles in saline lakes,and obtained a series of research findings.Finally,a summary of the microbial effects on carbon and nitrogen cycling in lakes is presented,and prospects for future development directions are proposed.
