On June 25, Professor Wang Chaoqun from China Agricultural University was invited to deliver the 20th installment of the Watershed Ecological Security Lecture Series at our university. The lecture, titled “Soil Microbial Carbon-Energy Coupling Metabolism and Carbon Sequestration”, was held in Room 305 of the Water Resources Building on the East Campus and chaired by Jiao Zhujin, Vice Dean of the School of Water Resources and Modern Agriculture.

In his presentation, Professor Wang first highlighted a critical gap in current soil carbon cycle models—the lack of an energy dimension. To address this bottleneck, he innovatively constructed a theoretical system of microbial carbon-energy coupling metabolism, laying a theoretical foundation for more accurate soil carbon cycle modeling. He further proposed a theoretical framework for soil organic carbon turnover based on microbial thermodynamic mechanisms, effectively filling the gap in the energy dimension of carbon cycle models. Additionally, Professor Wang elucidated the dynamic coupling relationship between microbial carbon and energy metabolism and its response mechanisms to environmental changes, providing robust scientific support for developing precise soil carbon sequestration strategies.

During the post-lecture discussion session, Professor Wang engaged in in-depth exchanges and discussions with faculty and students on the application potential of this theoretical technology in carbon cycle research across diverse environments such as water bodies and riparian zones. His cutting-edge research outcomes and unique perspectives have provided important new ideas and theoretical references for scientific research in the fields of watershed ecological security, water environment protection, and carbon cycling.
