气候变化能显著地影响碳森林生态系统骑车。日报、季节在 Cinnamomum camphora 和 Liquidambar formosana 森林的土壤呼吸(R s ) 的动力学被每个月在 2006 使用 Li 英国管 6400-09 的红外线的煤气的交换分析器调查。土壤温度和潮湿也被测量。日报在与每天改变的 R s 的变化在二个森林里玷污温度。越过成长季节，土壤呼吸由于更高的土壤温度和潮湿条件在 7 月 28 日达到顶点。季节的 R s 变化被土壤温度主要影响。在 C 的季节的土壤呼吸。camphora 和 L。 formosana 森林是强烈与在5厘米的深度的土壤温度(x)有关( R s = 0.1598e0.1377x ( R 2 = 0.9289 ， P = 0.001 )并且 R s = 0.2177e0.0962x ( R 2 = 0.927 ， P = 0.000 ))，当年度吝啬的 R s 率是 2.614 和 1.397 摩尔 m 时? 2 s ? 1 并且 Q 10 价值分别地为二个森林是 3.96 和 2.62 。然而， R s 没被季节的变化在 2006 在二个森林里在土壤潮湿(w) 影响。我们开发了二个方程(R s =? 0.020w 2+0.497w+0.562 (R 2 = 0.109， P > 0.05 ) ， R s =? 0.001w 2+0.072w+0.731 (R 2 = 0.053， P > 0.05 )) 描述在 R s 和土壤潮湿之间的关系。当土壤潮湿低于 12.43% 和 18.00% 时，在 R s 和土壤潮湿之间的一种积极关系被观察，但是什么时候玷污潮湿，超过了 12.43% 和 18.00% 的阀值价值，土壤潮湿为 R s 成为了抑制因素。土壤呼吸和潮湿的长期的观察被要求理解土壤呼吸的时间的动力学。

英文摘要：

Climate change can significantly affect carbon cycling of forest ecosystems. The diurnal and seasonal dynamics of soil respiration （Rs） in Cinnamomum camphora and Liquidambarformosana forests were investigated by using infrared gas exchange analyzer of Li-Cor 6400-09 each month in 2006. Soil temperature and moisture were also measured. Diurnal variations in Rs varied with daily soil temperature in the two forests. Across the growing season, soil respiration peaked on July 28 due to higher soil temperature and moisture conditions. Seasonal Rs variations were predominantly influenced by soil temperature. Seasonal soil respirations in C. camphora and L. formosana forests were strongly related to soil temperature （x） at 5-cm depth （Rs = 0.1598e^0.1377x （R^2 = 0.9289, P = 0.001） and R^2= 0.2177e^0.0962x （R^2 = 0.927, P = 0.000））, while annual mean Rs rate was 2.614 and 1.397 μmol m^-2 s^-1 and Q10 values were 3.96 and 2.62 for the two forests, respectively. However, Rs was not influenced by seasonal changes in soil moisture （w） in the two forests in 2006. We developed two equations （Rs = -0.020w^2＋0.497w＋0.562 （R^2= 0.109, P 〉 0.05）, Rs = -0.001w^2＋0.072w ＋0.731（R^2= 0.053, P 〉 0.05）） to describe the relationship between Rs and soil moisture. A positive relationship between Rs and soil moisture were observed when soil moisture was below 12.43% and 18.00%, but when soil moisture exceeded threshold values of 12.43% and 18.00%, soil moisture became the restraint factor for R^2. Long-term observations of soil respiration and moisture are required to understand the temporal dynamics of soil respiration.
