摘要
本文以藏东南具有典型垂直山地地带性的色季拉山为研究区,揭示了青藏高原高寒山区季节性冻土有机碳储量对坡位的响应特征。研究表明,坡位对土壤有机碳储量有显著影响,未来碳循环的预测应充分考虑微地形对坡面尺度下土壤碳垂直分布、碳库组成和空间变异的影响。
In this paper,the Sejila Mountains with typical vertical mountain zonality in southeastern Tibet are taken as the research area,and the response characteristics of the seasonally frozen soil organic carbon storage in the alpine mountains of the Qinghai-Tibet Plateau to the slope position are revealed.Studies have shown that slope position has a significant impact on soil organic carbon storage,and the prediction of future carbon cycle should fully consider the impact of microtopography on the vertical distribution of soil carbon,the composition of carbon pools and spatial variability at the slope scale.
