英文摘要	Warming affects forest soil denitrification and nitrogen losses. The authors show that temperature enhances nitrous oxide and dinitrogen but varies by soil; temperature sensitivities are similar across soils but are higher for dinitrogen, suggesting complete denitrification in a warmer climate. Soil nitrous oxide (N2O) and dinitrogen (N-2) emissions from denitrification are crucial to the nitrogen (N) cycle. However, the temperature sensitivities (Q(10)) of gaseous N losses in forest soils are poorly understood, with implications for prediction of N cycle responses to warming. Here, we quantify temperature sensitivities of denitrification-derived potential N2O and N-2 production. Using soils from 18 forest sites in China along a 4,000 km north-south transect we find that N2O and N-2 production rates increased with temperature, with large variations across soils. In contrast, the Q(10) values for N2O (2.1 & PLUSMN; 0.5) and N-2 (2.6 & PLUSMN; 0.6) were similar across soils. N-2 was more sensitive to temperature than N2O, suggesting that warming could promote complete denitrification. Moreover, the Q(10) for denitrification (2.3 & PLUSMN; 0.5) was comparable to Q(10) for aquatic sediments. This finding of universal temperature sensitivity of gaseous N losses from denitrification will facilitate modelling N losses in response to warming globally.
