The results were as follow: At fine, cloudlet and cloud weather in rainy season,the mean value of CO 2 content varied in a range of 349 to 350ml/m\+3 at 2.8m above the canopy, 346 to 348ml/m\+3 at 0.8m above the canopy, 345 to 349ml/m\+3 at 16m inner the forest and 352 to 357ml/m\+3 at 5m above ground in the period from 9:00 to 18:00.The CO 2 content in rainy season was lower than that in dry season. At the same weather and space-time, CO 2 content in rainy season was higher than that of CO 2 in dry season at both day and night. According to the grads calculation, there were the CO 2 flux from atmosphere to canopy with 0.61×10 -6 and 0.71×10 -6kg/(m 2·s) during day time in dry and rainy seasons respectively.
