      摘要: 通過(guò)綜述和評價(jià)中國土壤,特別是農田土壤有機碳庫(以下簡(jiǎn)稱(chēng)碳庫)的現狀與演變態(tài)勢, 討論其對我國應對氣候變化的意義, 提出了我國土壤碳庫及其演變與應對氣候變化的基本國情是:1) 我國土壤背景碳儲量較低且區域分布不均衡;2) 我國土壤固碳效應明顯,未來(lái)固碳減排潛力顯著(zhù);3) 技術(shù)和政策是實(shí)現和提高我國土壤碳匯、促進(jìn)我國應對氣候變化能力建設的重要途徑。建議進(jìn)一步加強對我國農田土壤固碳減排的研發(fā)投入, 完善農業(yè)應對氣候變化的相關(guān)政策和鼓勵措施體系,研究構建氣候友好的新型農業(yè),以期在提高和穩定農業(yè)生產(chǎn)力與應對氣候變化能力上獲得雙贏(yíng)。

      Abstract: This paper overviews the studies on soil organic carbon (SOC) stock and dynamics of China's soils since the fulfillment of the second national soil survey, and focuses on the significance of climate change mitigation in China. The status of SOC stock and the dynamics of China are characterized of a relatively low C storage with a large regional variability, a definite overall trend of C enhancement, and a significant sequestration potential in the future, which can be realized through a sound climate policy and the adoption of the best management practices in agriculture. Increasing investment in C sequestration research and technology development, improving policies and incentives for enhancing C sequestration, and the innovation and extension of climate-friendly agricultural systems should be pursued for a win-win effect in enhancing both the productivity of China's agriculture and climate change mitigation.

      Key words: China, soil organic carbon stock, climate change, carbon sequestration, croplands
