摘要:
 利用均质化土壤重装的土柱，在川西亚高山-高山同一坡面的5个海拔高度（3 250、3 438、3 672、3 852 m和4 098 m）进行原位培养，定期采样测定土壤0～10 cm和10～20 cm水溶性有机碳（DOC）含量，揭示高寒土壤水溶性有机碳时间动态及受海拔高度的影响规律。结果表明，川西亚高山-高山森林土壤DOC主要在每年11月至次年5月的低温期间积累，在低温末期（5月）含量达到最高，土壤DOC含量在5月以后的温暖季节因消耗而逐步降低；在同一采样时间土壤DOC含量均随着海拔升高而增加。因此，因全球变暖而引起的高寒土壤低温期间缩短，将减少土壤DOC累积的时间，而可能使土壤中DOC含量降低；同时低温期缩短将可能使高寒土壤DOC消耗期延长，从而使高寒土壤碳成为一个潜在的碳源。
Abstract:
 Change patterns of dissolved organic carbon (DOC) along elevation gradients are important to elucidate responses of alpine cold soil carbon and its labile fractions to global change and soil warming. Repacked columns of homogenized alpine topsoil (0-20 cm) were incubated on-site at different altitudes (3 250, 3 438, 3 672, 3 852, and 4 098 m) along an altitudinal gradient. Incubated soil columns were sampled in September, November, March, May and July, respectively, and DOC contents in 0-10 cm and 10-20 cm in each column were respectively analyzed to determine seasonal variability in soil depth and altitude. The results showed that soil DOC was accumulated during the cold season and reached the peak in May, while decomposed in growth season; at the same sampling time, the contents of DOC tended to increase with altitude, soil DOC content at high-altitude zone was higher than at lower-altitude zones. Therefore, for subalpine soil, shrinkage of cold season induced by climate warming may extend the period of DOC depletion. Meanwhile, soil warming and contraction of freezing period could decrease the accumulations of soil DOC and enhance emissions of CO2, indicating that alpine cold soil carbon pool would become a potential carbon source in the context of soil warming.
