The phyllostachys edulis are the most important composition of forest resources in the south of China. In order to quantify soil respiration dynamics and its regulating factors, we conducted a set of relevant experiments in phyllostachys edulis forest in west Tianmu Mountain, Zhejiang province. Soil respiration rate and relevant factors were measured by Li-cor8100 from May 2007 to March 2008, then we investigated soil enzyme activities above 20cm surface. Results were displayed as follows: (1) Soil respiration of phyllostachys edulis forest emerged typical diurnal and seasonal dynamic patterns. The diurnal variation was gentle, the mean soil respiration showed significant difference among seasons (P < 005); the maximum (5.99μmol?m-2?s-1) appeared in August 2007, the minimum (1.08μmol?m-2?s-1) appeared in January 2008. (2) Regression equation analysis showed that the relationship between soil respiration and soil temperature of 5cm depth can be described as an exponential equation, and it was very significant (P< 0.001). The relationship between soil respiration and soil volumetric water content can be described as linear equation, but it was not significant (P> 0.05). The relationship between soil respiration and near-surface atmospheric temperature were described as an exponential equation, it was a close relation (P< 0.001). The relationship between soil respiration and CO2 concentration were described as a liner equation, it was a significant correlation (P< 0.05). (3)Correlation analysis showed that urease, sucrase and cellulase activities and soil respiration were positively correlated, but only the activity of cellulase achieved a significant level. All of these results suggest that soil temperature is a dominant factor to impact soil respiration, yet the effect of near-surface atmospheric conditions and soil enzymes could not be ignored.
