2026-08-31 Characteristics of Soil Organic Carbon Structure in the Black Soil Region of Northeast China and Its Influencing Factors doi:10.57760/sciencedb.iga.0019n en This study used ¹³C nuclear magnetic resonance spectroscopy to examine soil organic carbon structures in four representative black soil regions: Hailun, Qiqihar, Changchun, and Shenyang. Significant regional differences were observed in organic carbon composition and stability, with mean annual temperature identified as an important influencing factor. The findings highlight the need to monitor active organic carbon decomposition and carbon-pool changes in colder regions under future climate warming.
