冻土图案的形成源于重力和奇特的物理现象

Per Eos (AGU), researchers have found that patterned frozen soils on Arctic slopes — displaying circles, stripes and polygons — arise from melt‑water sliding downhill and forming terrace‑like solifluction deposits. By coupling physical models, remote‑sensing data and analog experiments with a cornstarch‑water Oobleck slurry, they explain how differing moisture levels create uneven soil accumulations that later collapse before the next flow. According to Eos (AGU), the work also offers a way to interpret comparable landforms on Mars and to anticipate how warming may destabilize slopes in high‑latitude regions. The team acknowledges the model’s limits but hopes to eventually test it in the field, despite the centuries‑long timescales involved.
