摘要：Both soil temperature and soil water condition are important factors that influence soil respiration at different forest. In this study, a throughfall exclusion experiment was carried out to explore effects of increased soil temperature and decreased soil water content on soil respirations in the bamboo forest in North Zhejiang of China. The results showed that 1) monthly variation in soil respiration ranges from 2.00 to 0.63 mu mol . m(-2) . s(-1) and 2.20 to 0.66 mol.m(-2).s(-1)in throughfall exclusion and control plots respectively. The soil respiration monthly variation following the monthly variation of soil temperature and in contrast to the monthly soil water content. 2) Soil temperature can explain 65.5%and 73.9% of the variance of soil respiration in throughfall exclusion and control plots respectively. Multivariate linear model based on temperature and soil water content explained 66.9% and 73.4% of the variance of soil respiration in throughfall exclusion and control plots respectively. Soil water content had no significant relationship with soil respiration. Q(10) values of throughfall exclusion and control plots were 5.99 and 4.44.
