摘要：

2011-11—2012-03，利用Li-6400系统测量锐齿栎林及其皆伐迹地土壤呼吸速率，研究锐齿栎林及其皆伐迹地休眠季土壤呼吸速率日变化、月变化和温湿度对土壤呼吸变化的影响，并估算休眠季锐齿栎林和皆伐迹地的土壤碳通量。结果表明：除2012年2月外，皆伐迹地土壤呼吸速率日变化幅度均大于对照林地；休眠季皆伐迹地和对照林地土壤呼吸速率均值分别为0.45和0.60 μmolCO₂·m^-2s^-1，差异显著（P<0.05）；无论是单因素模型还是双因素模型，其拟合方程的决定系数均表现为对照林地高于皆伐迹地；在土壤呼吸双因素模型中，5和10 cm深处土壤温湿度分别解释了皆伐迹地土壤呼吸速率变化的81.5%和82.0%，解释了对照林地的92.8%和89.0%；休眠季皆伐迹地和对照林地土壤碳通量分别为86.4和106.8 gC·m^-2。

Abstract:

By using a Li-6400 portable photosynthesis system with a soil chamber, the diurnal and monthly dynamics of soil respiration rate was measured in a Sharptooth Oak forest (Quercus aliena var. acuteserrata, served as control site) and its clear-cutting site in Xiaolong Mountain within the dormant season from November 2011 to March 2012 in order to investigate influences of the soil temperature and moisture on the soil respiration rate, and to estimate the soil carbon fluxes in the Sharptooth Oak forest and its clear-cutting site. The results showed that the daily variation in the soil respiration rate in clear-cutting site was greater than that in control site within the dormant season except February, but the mean value of the soil respiration rate in clear-cutting site was 0.45 μmol CO₂·m^-2s^-1, smaller (P<0.05) than that of the control of 0.60 μmol CO₂·m^-2s^-1. Regardless for the single and double factor models, the determination coefficients of fitting models for the control site were higher than that for clear-cutting site. With the double factor model, changes of the soil respiration rate could be explained 81.5% and 82.0% by the soil temperature and moisture at 5, 10 cm depth in clear-cutting site, respectively, and could be explained 92.8% and 89.0% by them at the same depth in control site, respectively. In the dormant period, the soil carbon effluxes in the clear-cutting site and the control site (forest land) were estimated to be 86.4 and 106.8 gC·m^-2, respectively.
