Positions open: High-performance computing (HPC) based human-environment interaction modeling Lab

Lab introduction: Quantitatively modeling and predicting human-environment relations (HER) and their changes are to be an important research direction in future Earth Science. The key question is how to meet the demands of human development without scarifying ecological security, polluting environment, overusing resources. Research subjects include developing HPC-based digital systems for modeling human-environment interaction processes, quantifying the relations among human and natural components, clarifying the safe-operating boundaries according to ecosystem functioning, analyzing stability and resilience of human-environment interactions, so as to guide and regulate human activities within environmental limitations, support social development planning, and facilitate sustainable development through using the scientific modeling tools. The accomplished research works of the team include: (1) The FOTAR representation framework（Fields, Objects, Time, GeoAgents & Relations, IJGIS 2009）for modeling human-environment interactive interactions and relations; (2) a prototype of GeoAgent-based Knowledge System for knowledge-oriented representation of human-environmental interactions; (3) a DNDC-based biogeochemical modeling system for simulating carbon, nitrogen and water processes, and predicting grain yields in agroecosystems at the national and global scales. Dr. Xiao Huang has expanded the site-level DNDC to regional decision support system GDNDC by integrating model parameter optimalization, risk analysis and scenario analysis; (4) application of such tools for quantifying the changing relations among national agricultural production, anthropological nitrogen discharges, and water quality changes, assessing agricultural drought risks and flood risks under socioeconomic changes, and human impacts on land-to-sea carbon transfer. Recent research priorities are enhancing model development of carbon-nitrogen-phosphorous-water coupling in land ecosystems; embracing hydrological, hydraulic and aquatic environment modeling; livestock and fish farming modeling; socioeconomic modeling for increasing the early warning capabilities for agricultural production and environmental changes, and exploring sustainable approaches to meet the common goals of social development and environmental protection. The team published works have been selected as one of major scientific achievements of China basic research development in Astronomy and Earth Science during the 13th Five-Year plan that issued by the Ministry of Science and Technology of P.R. China, 2022; one of China’s representative scientific achievements in 2019, issued by Chinese Academy of Sciences, 2021; and the 2020 Top Ten Progresses in China's Agricultural Science, issued by Chinese Agricultural Academy of Sciences, 2020.

Recent research priorities are enhancing embracing hydrological, hydraulic and aquatic environment modeling; livestock and fish farming modeling; socioeconomic modeling for increasing the early warning capabilities for agricultural production and environmental changes, and exploring sustainable approaches to meet the common goals of social development and environmental protection.
