\begin{abstract}
Patterns and elevational controls on the response of soil organic matter
(SOM) decomposition to temperature in alpine forest soils are critical
to efforts to quantify the regional carbon cycle-climate feedback, but
are not well known. Here, we report rates of soil organic matter (SOM)
decomposition (Rs) and temperature sensitivity (Q10) determined in a
short-term laboratory incubation with a gradual warming from 5\selectlanguage{ngerman}°C to 29°C
of soils from different elevations in the Qilian Mountains, China
(2,600, 2,800, 3,000, and 3,200 m). The results showed the Rs
significantly increased with increasing elevation (P\textless{}0.001).
Across all elevations, RS first showed an increasing trend at
temperatures \textless{} 20 \selectlanguage{english} and then declined substantially, most
likely in response to the content of labile C (greater at the start of
incubation, and declining over time). Q10 of SOM decomposition increased
significantly with increasing elevation and deceasing incubation
temperature (P\textless{}0.001). More importantly, soil organic carbon
(SOC), total nitrogen (TN), 1-2 mm aggregate-associated OC, and
elevation were the main control factors affecting Rs and Q10. These
results indicate that high-altitude soils in alpine forests of the
Qilian Mountains are relatively more sensitive to temperature changes,
and have greater potential to release CO2 due to higher SOC contents and
1-2 mm aggregates-associated OC than low-altitude. The findings could
serve as a reference for how regional C pools may respond to future
warming in alpine forests of the Qilian Mountains.%
