报告摘要：

Simulating amount and intensity of water uptake induced by plant roots are vital in agricultural science, environmental ecology and relevant engineering technology. Plant water uptake is sensitive to soil water pressure. However, continuous soil water extraction and evaporation can reduce soil water content and pore water pressure, resulting in decrease of plant water uptake. The relationships of these interactions with plant morphology, soil properties and atmospheric conditions were emerging questions in simulations of root water uptake. This presentation will introduce how scientists and engineers could use a newly developed model to simulate soil water distribution resulted by soil water extraction using differential equations and numerical tools. Additionally, how two major challenges in this study, difficult in experiments, are eventually solved by mathematics. One is how to theoretically integrate previous results of different plant organs to model the behavior of entire plants. The other is how to determine the intensity of root water uptake in experiments, which is unable to be measured directly but essential for verification of a new model.

讲者简介：

Dr Wang Zi Jian obtained his bachelor degree in 2013 and doctor degree in 2019, both in civil and environmental engineering from Hong Kong University of Science and Technology. He continued as visiting scholar in the same institute for another year before joining UIC in 2021. Dr. Wang is an expert in plant physiology and geotechnical engineering. Guided by mathematical models, he has conducted successful theoretical and experimental cross-disciplinary studies related to geotechnical engineering, environmental ecology and agricultural science. His multi-disciplinary research focuses on atmosphere-plant-soil interactions, carbon neutrality, coping strategy of extreme climates for plants and soil pollution remediation.
