The Institute of Soil and Water Resources and Environmental Science focuses on the efficient use of soil and water resources and their environmental protection. It consists of the National Key Laboratory of Agricultural Resources and Environment, the National Engineering Laboratory of Agricultural Soil Pollution Prevention, Control and Remediation Technology (jointly built), as well as the Key Laboratory of Polluted Environment Remediation and Ecological Health of the Ministry of Public. The Institute can receive doctoral candidates and post-doctoral researcher in the fields of "Soil Science" and "Water Resources Utilization and Protection". The Institute has a high academic and research level, with the National Foundation Innovation Research Group on "Soil Pollution Process and Remediation Principles" and the Innovation Team of the Ministry of Agriculture on "Environmental Quality of Origin and Agricultural Product Safety". Several members in the team have been selected by the National "Thousand Talents Program", Changjiang Scholars of the Ministry of Education, Young Changjiang Scholars of the Ministry of Education, National Outstanding Youth Foundation, National Excellent Youth Foundation, National "Hundred Million Talents Project", National "Ten Thousand Talents Program", and National Outstanding Talents in Agricultural Research At present, there are 35 members (31 of them have doctoral degree) in the Institute, including 21 full-time researchers, 12 professors, 16 doctoral supervisors.
We focus on the physical/chemical/biological process and coupling mechanism of soil nutrients and pollutants (heavy metals, pesticides and persistent organic pollutants, pathogens, new pollutants, etc.) at different scales, including soil biodiversity and its ecosystem service function, soil barrier factor reduction and fertility enhancement, model simulation, indicators and evaluation system of healthy soil, etc., thus providing scientific basis and technical support for the improvement of arable land quality and targeted cultivation of healthy and high-quality soil.
We focus on the soil and water pollution characteristics of agricultural surface source pollutants (nitrogen, phosphorus, pesticides, heavy metals, new pollutants, etc.,), including multi-scale simulation of nitrogen and phosphorus and other agricultural surface source pollution processes, regional soil organic, inorganic, biological pollutants composition, safe utilization of agricultural product and contaminated soil, the research and development of soil/groundwater and surface water ecological remediation, thus providing key scientific and technological support for soil pollution prevention and agricultural surface source pollution manage.
We focus on the mechanism of interaction network among soil microorganisms, protists, animals, and plant roots, to investigate the functional regulation of these organisms on soil physicochemical properties, element cycling, plant nutrients uptake and disease resistance. We conduct some new approaches, including multi-omics analysis, gene editing technology, microfluidics, and machine learning, to clarify the key driving factors of root exudates and their biological recruitment in soil biological interaction and regulation, thus providing theoretical and technical support for the development of modernized agriculture.
We focus on the carbon and nitrogen cycle processes in terrestrial ecosystems and their response and feedback to global change and clarify the role of these processes on food security, environmental protection, ecological services, and dual carbon strategies. To elucidate the key paths and countermeasures for nitrogen reduction and carbon sequestration in agricultural ecosystem, some new methods are developed to study carbon and nitrogen cycle-environmental response-global change, including model simulation, big data analysis, multi-source data integration, econometric analysis, cost-benefit analysis. By innovating the carbon and nitrogen cycle prediction technologies and control strategies from regional to global scales, we aim to provide theoretical and technical support for China's ecological civilization, soil health, and sustainable agricultural development.
