Abstract: An automated chamber system LI—8100 was used to study how soil respiration differed with spatial and temporal in moso bamboo (Phyllostachys pubescens) plantations on the different elevations, in Dagangshan mountain range, Jiangxi province. Different mathematical models were used to describe the relationship between soil respiration and soil temperature, soil water content. The results showed that, at the diurnal scale, soil respiration decreased with elevation and had a similar temporal trend with soil temperature. Soil temperature at different depths(soil surface, 10, 20 and 30 cm depth)all had significant effect on soil respiration (P<0.1), and the 10 cm depth had an very significant (P<0.05) effect on soil respiration. The Van’t Hoff model had higher R2 than Lloyd and Taylor equation. The relationship between soil water content and soil respiration was smaller and could be described by linear equation (R2=0.133—0.377). After normalized the soil respiration at 10 ℃ (R10), the correlation between R10 and soil water content was enhanced (R2=0.303— 0445). Compared with the R2 of onedimensional equation, the R2 of the twodimensional equation (R2=0.450—0.768) increased to some extent.
