摘　　要：0 INTRODUCTION Permafrost refers to the ground that remains frozen year-round in polar and high-altitude regions,and its structure has traditionally been described by two distinct layers:the active layer and the permafrost layer(Dobiński,2011;French and Shur,2010;Muller,1943).The active layer undergoes seasonal cycles of thawing and freezing,which significantly influence hydrological cycles,biogeochemical processes,and ecosystem productivity(Dobiński,2020;Luo et al.,2023).
