Abstract
The present invention discloses a method for estimating soil organic carbon in karst area, including: step 1, establishing a soil organic carbon estimation model for the karst area; step 2, revising a soil depth; step 3, subtracting an exposure rate of bedrock for different types of soil and positive and negative terrains; step 4, revising a soil organic carbon density estimation formula for different types of soil and positive and negative terrains; and step 5, revising a soil organic carbon storage estimation method. This invention has solved the problem of overestimating soil organic carbon pool by existing methods, has improved the calculation accuracy, and has promoted the research process of soil carbon cycle in karst area.
