摘  要:
陆地生态系统碳循环是全球碳循环的重要组成部分,在全球碳收支中占主导地位。大气CO2浓度升高直接或间接地影响土壤碳的固定,碳在土壤的不同固定机理反映了碳的稳定性和周转过程,本文综述了影响碳固定的物理、化学和生物学机理,土壤碳固定的不同状态发生的主要机理不同;受大气CO2浓度升高影响时间长短不一,主要过程有所侧重,但三种机理相互影响。

摘  要:
The carbon cycling in terrestrial ecosystem is an important part and plays a dominant role in global carbon budgets. Elevated CO2 affects the carbon sequestration directly or indirectly, so the different meclanisms of carbon sequestration in soil could reflect the stabilization and turnover of soil carbon. This paper reviews the different mechanisms affected soil carbon sequestrition in the way of physics, chemistry and biology.
