      abstract     = {It is a concern whether the effect of soil type on N2O
                      emissions has to be considered for regional mitigation
                      strategies and emission estimates in mountainous areas with
                      inherent spatial heterogeneities of soil type. To date,
                      there were few field experiments which investigated soil
                      type effects on N2O emissions. Thus a 2-year field study was
                      conducted to measure N2O emissions and soil environmental
                      variables from three different soils that were formed from
                      similar parental rock under the same climate. Seasonal N2O
                      fluxes ranged from 0.18 to 0.40 kg N ha−1 for wheat
                      seasons and 0.40 to 1.50 kg N ha−1 for maize seasons
                      across different experimental soils. The intra- and
                      inter-annual variations in N2O emissions were mainly
                      triggered by temporal dynamics of soil temperature and
                      moisture conditions. On average, seasonal N2O fluxes for
                      acidic soils were significantly lower than for neutral and
                      alkaline soils in cold-dry wheat seasons while significantly
                      greater than for neutral and alkaline soils in warm-wet
                      maize seasons. These determined differences of N2O emissions
                      were mainly caused by differences of initial soil properties
                      across different soils. Moreover, seasonal N2O fluxes were
                      positively correlated with soil pH in wheat seasons, but
                      negatively correlated in maize seasons. The temperature
                      sensitivity coefficient (Q10) of soil N2O emissions for
                      acidic soil (4.06) were significantly greater than those for
                      neutral (1.82) and alkaline (1.15) soils. Overall, N2O
                      emissions for acidic soils were not only higher than those
                      for neutral and alkaline soils but also more sensitive to
                      changing temperature. The present study highlights that soil
                      type is needed to be carefully considered for regional
                      estimate and proposing mitigation strategy of N2O emissions
                      especially in subtropical mountain regions with inherent
                      great heterogeneity of soil type.},
