摘要 我国是一个农业大国，研究我国典型农作区作物生产碳汇对于估算区域碳收支和制定应对气候变化的管理政策有重要的意义。全国6个典型农作区中主要农作物生产整体表现为碳汇。同一区域内不同作物的碳汇量差异明显，同一作物在不同区域之间差异显著。全国年土壤有机碳储量整体表现为碳汇，不同区域年土壤有机碳储量的范围为–2.07 TgC·y–1~19.95 TgC·y–1。

| Abstract：China is a big agricultural country. The research on the carbon sink function of crop production in China’s typical agricultural areas plays an important role in estimating the regional carbon budget and making management policies to tackle climate changing issue. The production of staple crops can be generally reflected by their carbon sinks. The carbon sinks of different crops in the same area differ greatly, and the carbon sink of the same crop also differs in different areas. The national annual reserve of soil organic carbon can be generally embodied in its carbon sink as well. The annual reserves of soil organic carbon in different areas range between –2.07 TgC·y–1 and 19.95 TgC·y–1. |
