摘      要：The objective of this study was to quantify both soil organic carbon(SOC)and soil inorganic carbon(SIC)stocks in different ecological zones in Xinjiang Region,the largest arid and semi-arid region in northwest *** specific focus was on the vertical distributions of 641 typical soil profiles(0-100 cm).The study region covered five ecological zones:I-Altai/west Junggar;II-Junggar basin;III-Tianshan mountain;IV-Tarim basin;and V-Kunlun-Altun *** zones are categorized by their specific geographical locations from north to south with terrains derived from mountains to *** data used in the study were obtained from the first(1960s)and the second(1980s)National Soil Surveys and partially from the field survey of this study conducted in *** results suggest that there are 11.74 Pg SOC and 26.71 Pg SIC total stocks in the 0-100 cm surface soil over the entire study *** distributions of SOC and SIC were found to be *** Tianshan mountain zone has the highest SOC stock,followed by the Tarim basin,Kunlun-Altun mountains,Altai and west Junggar(Altai/west Junggar),and Junggar basin *** contrast,the Tarim basin zone had the highest SIC stock,followed by the Tianshan mountain,Kunlun-Altun mountains,Junggar basin,and Altai/west Junggar *** SOC content decreases gradually from northwest to southeast and from mountains to deserts;while the SIC content decreases gradually from south to *** SOC and SIC contents also change with soil *** a given ecological zone,the SOC content increased with increasing soil depth,peaked at about 20-40 cm,then it decreased with the bigger depths below 40 *** SIC contents increased gradually from 0 to 40 cm,and then decreased gradually with increasing soil depth over the 40-100 cm depth in all ecological zones except for the Tianshan mountain area.
