海岸带潮滩生源要素生物地球化学循环过程是国际地圈生物圈计划(IGBP)、海岸带陆海交互作用(LOICZ)研究的重要内容,也是全球变化区域响应研究中的重要组成部分。在过去的10～20年之间,潮滩生源要素氮的生物地球化学循环研究得到了长足的发展。基于此,较为全面、系统地总结和分析了有关潮滩氮营养盐的来源、潮滩氮素的物理、化学和生物迁移转化过程及氮素地球化学循环过程中底栖生物效应等一系列研究成果,并提出了今后潮滩生源要素氮的生物地球化学循环研究重点和发展趋向。
Coastal tidal flat Biogenic geochemical cycling is an important part of IGBP and LOICZ research and an important part of global change regional response research. In the past 10 to 20 years, tidal flat biogenic nitrogen element biogeochemical cycle has made considerable progress. Based on this, a series of studies on the source of tideland nitrogen nutrients, the physical, chemical and biological migration and transformation processes of tidal flat nitrogen and the benthic organisms in the process of nitrogen geochemical cycle are summarized and analyzed systematically and systematically And put forward the research focus and development trend of biogeochemical cycles of nitrogen in future tidal flat.
