Complex Processes and Nonlinear Evolution of Aeolian Landscapes in Response to Climate Change

Aeolian landscapes in arid regions are highly sensitive to global climate change and play a key role in Earth surface systems through various feedbacks. Their evolution is driven by multi-scale, multi-factor interactions and often involves complex dynamics, including multiple stable states and self-organized criticality. This presentation focuses on the extensive deserts and dune fields of northern China, which offer a unique setting for exploring the evolution of wind-driven sedimentary systems and their responses to climatic variability. First, the long-term evolution of aeolian systems from the late Cenozoic through the Quaternary to the Last Glacial Maximum will be reviewed, with particular attention to how landscape stability responded to global temperature fluctuations and monsoonal variations at tectonic and orbital timescales. Next, the spatial heterogeneity and nonlinear behavior of semi-arid dune systems during the Holocene will be examined, highlighting the phenomenon of dune bistability, in which active and stabilized dunes coexist under similar climatic conditions for millennia. Additionally, by integrating remote sensing, field observations, machine learning, and modeling, this study identifies critical thresholds and transitions in dune system dynamics, and explores their potential trajectories under future climate scenarios. The presentation emphasizes the value of interdisciplinary approaches in unraveling the complex, nonlinear processes that shape aeolian landscapes, with implications for sustainable dryland management and desertification mitigation in a changing climate.
