We use a systems modeling approach to understand, quantify, and predict ecosystem processes and patterns in response to climate change, land use, land management, and atmospheric composition at multiple scales from watershed, landscape to regional, national, and global. Our research aims at exploring the underlying mechanisms controlling integrated biogeochemical and hydrological cycles in a coupled human-natural system, and mimicking them through process-based ecosystem modeling. Our work involves mathematic modeling, large-scale data development, data-model integration, geospatial and statistical analysis. Overall, it can serve as a powerful tool for assessing the provision of ecosystem goods and service, and identifying better management practices and mitigation options for a sustainable earth. Our current research activities include:
Ecosystem model development and improvement
Use modeling approach to scale up plot-level field observation to watershed, landscape, regional and global, improve model representation of key biogeochemical and hydrological processes through data-model fusion.
Modeling of belowground processes
Identify belowground processes with largest uncertainty in modeling study and improve model representation of C-N coupling, and nitrogen transformation in soil.
Biogeochemical and hydrological cycling with real world practices
Apply modeling approach as a decision-support tool to identify optimized nutrient and water management options for reducing air and water pollution, mitigating climate warming, and maintaining food production.
Quantification of greenhouse gas balance
Quantify net biogenic fluxes of CO2, CH4 and N2O in terrestrial ecosystem in response to natural and anthropogenic disturbances, and assess the consequences of management practices to three gas together.
Investigate how environmental changes taken place on land would affect river discharge and C and N export, and thus affect coastal productivity and water quality.
