Abstract:
Data of soil respiration taken at the proper time that can represent the daily average value was widely used in annual soil efflux evaluation. In this study, we used an automatic measuring system to observe and collect the data of Xishuangbanna tropical seasonal rain forest soil respiration in January, April, July and October, 2009. The representative time period for soil respiration observation was estimated. Results showed that the errors of the mean values during 9:00—11:00 comparing with the daily average values in April, July and October were all less than 10 % under control,indicating that the values during the period could reasonably represent the daily average value. The errors could vary with months, were the lowest in October and the highest in July. Mean value of soil respiration and Q10 during 9:00—11:00, which was tested at multipleday scale, could well fit the daily average value.
