摘要
Global climate change has significantly altered the patterns of Annual Snow Cover(ASC),including glaciers,which in turn,have reshaped regional hydrological processes.These changes profoundly impact the weathering rates of continental rocks and their associated carbon sink potential,particularly for silicate(Eq.(1))and carbonate(Eq.(2))rocks under natural conditions[1-3].Low Temperature(Tem)in regions with ASC typically limit the rates of chemical weathering and the occurrence of weathering products.However,as the ASC melts,the chemical weathering processes previously suppressed by ice begin to accelerate progressively[3,4].In regions where ASC diminishes but does not fully expose the ground,increased meltwater alleviates the restrictive effects of solid moisture on regional chemical weathering.
