| 摘 要： | 阐述了土壤有机碳的概念,按土壤有机碳的化学组成、化学性质及其与不同大小的土壤颗粒结合的情况及比重等,主要从化学和物理两个方面综述了土壤有机碳的分类方法.认为土壤活性有机碳能够灵敏、准确、真实地反映土壤有机碳的存在状况以及土壤质量变化,提高土壤活性碳库有利于提高土壤肥力从而增加作物产量；而缓效性碳和惰性碳可能有利于土壤物理性质改善,土壤固碳增加可提高土壤应对气候变化的能力.

| Abstract: | The concept of soil organic carbon is described in the paper.According to the chemical composition and chemical properties of soil organic carbon,and its combination with different sizes of soil particles as well as the combination ratios,the classification methods for soil organic carbon mainly elaborated from chemistry and physics.The study indicated that the existence condition of soil organic carbon and the changes in soil quality can be sensitively,accurately and truly reflected by soil active organic carbon;improving soil organic carbon pool helps to enhance soil fertility,so that increase crop yield;the slow carbon and the inert carbon may help to improve soil physical properties,and the increase of soil carbon sequestration can heighten the ability of soil to cope the climate changes. |
