Abstract

Soil carbon bank of the Yellow River basin in China was estimated, by using the total carbon concentration and organic carbon content in the top and deep soil, and soil type and bulk density data. The results show that, from 2010 to 2018, the organic carbon reserves and the total carbon reserves of surface soil in the Yellow River basin increased by 581×106t and 692×106t. And the total carbon reserves and the total carbon reserves of deep soil in the Yellow River basin increased by 803×106t and 596×106t. It is indicated that the soil carbon reserves in the Yellow River basin have a large increasing trend between 2010 and 2018. This result can provide reference for the study of ecological environment change in China and the world.
