英文摘要 | A field experiment was carried out to examine the soil respiration rate in Abies fabri forests in Gongga Mountain National Nature Reserve using LI-6400-09 portable soil respiration chamber. The results showed that the soil respiration rate and soil temperature of mature and middle-aged A. fabri forests were different in each month. The soil CO2 emission rates of the two stands had obvious seasonal variation characteristics, which were arranged: summer > autumn > spring > winter; the monthly average soil CO2 emission rate of the mature aged forest ranged from 0.82 to 5.88 μmol/(s·m2), with the coefficient of seasonal variation of 50.6%; and the average monthly soil respiration rate of middle-aged forest was in the range of 0.52-3.52 μmol/(s·m2), with the coefficient of seasonal variation of 48.5%. The seasonal variation of soil CO2 emission rate was positively correlated with the 5 cm soil temperature. And the Q10 values of the soil CO2 emission rates in the mature and middle-aged A. fabri forests were 3.2 and 2.6, respectively, and the sensitivity index of CO2 emission to temperature in the mature A. fabri forest was higher than that in the middle-aged forest. |
