土壤环境中几种常量元素的生物地球化学研究进展

Research on Biogeochemical Cycling of Several Macroelements in Soil

通过对生物地球化学的概念以及生物地球环境化学循环进行阐述,进而得出了土壤环境生物地球化学循环的概念。通过对土壤中的生物地球化学循环所存在的物态进行分析,总结出土壤生物地球化学循环所研究的物态包括三种:即固、液、气三相物态。进而提出土壤生物地球化学中的几种主要养分元素碳、氮、磷、硫在液相物质或气相物质影响下,在土壤-生物界面之间进行迁移和传递的研究进展,得出其在生物地球化学循环中的作用。

The concept of biogeochemistry and biological chemical cycle were described as well as soil environmental biogeochemistry cycle. The state of matter in soil during the biogeochemical cycle was analyzed, the state includes three types： solid, liquid, gas phase. Several main nutrient elements in the soil biogeochemistry were put forward, such as carbon, nitrogen, phosphorus and sulfur. Research progress in their migration and transfer between soil and biological interface was discussed, its role in the biogeochemical cycle was obtained.
