英文摘要	Lakes in cold and arid regions have weak hydrological connectivity to their watersheds and serious soil erosion by wind, and are particularly sensitive to changes in underlying surface process and global climate changes, which may result in unique carbon cycles across the terrestrial-aquatic interface and ecological impacts. However, the roles of input pathways of terrestrial dissolved organic matter (TDOM) to lakes in cold and arid regions, especially the effects of possible TDOM input caused by wind erosion, has not been fully understood. Taking a typical lake in cold and arid regions as an example, this study comprehensively investigated the characteristics and contributions of dissolved or-ganic matter (DOM) input from different TDOM input pathways, ultimately highlighted the impacts of wind erosion from composition characteristics, historical changes and universal proofs. The results showed that DOM introduced by wind erosion contributed 37.34 % to all TDOM input, and exhibited the strongest humification and aromaticity, and greatest molecular weight and stability. The considerable input and refractory characteristics led to the differences in the TDOM distribution and DOM composition between the near-wind and far-wind shores of the lake. Moreover, historical analysis showed that wind erosion became the main way driving the changes in buried terrestrial organic matter in the lake through a combined action of precipitation and land cover changes after 2008. The pervasive impor-tance of wind erosion pathways on TDOM inputs in the cold and arid regions was further demonstrated through the proof from two other representative lakes. The findings also shed light on the possible impacts of wind erosion on ma- terial distribution, aquatic productivity, and energy input in lake ecosystems. The study provides new insights to broaden the content of global lake-landscape interactions and regional ecosystem conservation.
