Field of investigation

(1) Carbon Cycle in Terrestrial Ecosystems and Global Change

(2) Mechanisms of Organic Carbon and Its Components in Wetland Soils

(3) Research on Watershed Water Quality Changes and Driving Factors

(4) Migration and Transformation of Major Pollutants in Watershed and Interface Mechanism

Research Overview

Focuses on terrestrial ecosystem carbon cycling, wetland biogeochemistry, and the evolution of watershed water environments. The research is deeply rooted in the Ganjiang River Basin and Poyang Lake wetlands, aiming to reveal the patterns of material cycling driven by both global change and anthropogenic activities. Key research areas include:

(1)Watershed Water Quality Evolution and Regulation Mechanisms: Exploring the spatiotemporal evolution of water quality indicators, identifying the core landscape and environmental drivers, and quantitatively analyzing their ecological impact thresholds to provide a scientific basis for precise watershed management.

(2)Wetland Soil Carbon Cycling Patterns: Investigating the response mechanisms of wetland soil organic carbon and its fractions to environmental changes, and exploring the regulatory effects of hydrological rhythms on the stability of wetland carbon pools.

(3)Pollutant Migration and Interface Biogeochemistry: Elucidating the migration and transformation of heavy metals within the "soil-rhizosphere-plant" system, with a specific focus on rhizosphere interface mechanisms and the controlling role of iron plaque on pollutant bioavailability.
