Improved method and system for estimating content of organic carbon in lake sediment

The invention discloses an improved method and system for estimating the content of organic carbon in lake sediment, and relates to the technical field of environmental science and engineering. The method comprises the following specific steps: collecting a sediment undisturbed column core sample; carrying out multi-layer segmentation treatment on the undisturbed column core sample of the sediment, and measuring the density, the moisture content, the sediment median particle size and the bottom original layer sediment median particle size of the layered sample of the sediment; the content of the organic carbon is calculated according to an improved empirical formula by utilizing the measured value, the content distribution of the organic carbon in the sediment along the vertical direction can be more accurately reflected, the operation is simple and convenient, the result is accurate, and a scientific basis is provided for lake ecological monitoring and environmental protection. 本发明公开了一种改进的湖泊沉积物中有机碳含量估算方法及系统，
