摘要:
 梳理了土地利用碳源/汇途径，估算了2010年陕南不同土地利用方式的碳源/汇。结果表明：79%的碳源来自于建设用地；农作物、林业、林地碳汇分别占41.44%、31.12%、24.16%，区域碳吸收大于碳释放，净碳汇1 467 751 t C-eq；农作物碳汇区内差异很大，高值区在河谷地带，向两侧随高度增加递减，大巴山地高于秦岭山地；林业碳汇区内差异相对较小，河谷地带偏低，两侧山地区林业碳汇较高；两大盆地是净碳汇负值区，向周边山区碳汇逐渐增加，汉台区碳源密度值最高。
Abstract:
 The carbon source and sink of various land uses in southern Shaannxi in 2010 were estimated. The results were as follows:The construction land was the primary cause of carbon source, while corps,forestry and forest land were the main three types of carbon source;The corp carbon sink which was higher in Daba Mountainous areas than Qinling Mountainous area,and declined from the valley to the sides;The forestry carbon sink varied little form the valley with lower density to the flanks with higher density;The two great basins were the net carbon source,which accumulated gradually in its surroundings;The highest carbon source area was in Hantai district.
