1980-2014年新疆地区碳库时空动态研究

摘要

通过对1980-2014年新疆地区时空尺度上碳库的动态进行研究,结果表明,1997年之前气候变化波动相对较小,碳收支基本处于平衡状态,1998-2008年有2次较大的碳流失现象发生.南疆和北疆呈现出不同的碳汇趋势,碳汇发生在天山及阿尔泰山等山区的中低山带,昆仑山北部山区以及阿尔泰山南缘出现较大程度的土壤碳降低态势.%The dynamics of carbon stocks on the spatiotemporal scale of Xinjiang from 1980 to 2014 was studied.The results showed that the fluctuation of climate change was relatively small before 1997,and the carbon budget was basically in equilibrium,and between 1998 and 2008,there were two times large loss of carbon.It showed different trends of carbon sequestration in southern and northern Xinjiang,and carbon sequestration occurred in the low altitude of Tianshan Mountain and Altai Mountain,and a large extent of soil carbon reduction occurred in the northern mountainous area of the Kunlun Mountains and southern Altay Mountains.
