永冻土大地有着超凡脱俗之美,展示着地球微妙的律动节奏。但永冻土能保持永冻吗?永冻土的范围覆盖了北半球的大片区域。在冰岛中部的高地,附近冰河的夏日融水汇成纠缠不清的潺潺溪流,从两侧环绕着杂乱无章的池塘群。这些浅水池塘散布在不透水的土层之上,很有可能是由盛行风构造成形。 Permafrost earth has the beauty of the world, displaying the subtle rhythms of the earth. But can permafrost remain perpetual frozen? The area of ​​permafrost covers a large area of ​​the northern hemisphere. In the highlands of central Iceland, the summer melts of the nearby glaciers melt into tangled streams of gurgling streams, encircling the chaotic ponds from both sides. These shallow ponds spread over impervious soils, most likely shaped by prevailing winds.
