The experiment lasted 46 days,and the results indicated that:respiration speed of forest soil was higher than that of paddy soil during the whole experiment period,especially in the prophase;after the soil respiration speed was steady,the dynamic change of soil respiration speed of forest-soil and paddy-soil was consiste.

The results showed: there were very significant annual and daily changing patterns of the forest soil respiration compared with a secondary evergreen broadleaved forest.
