Abstract: Aerially seeded Pinus massoniana forest in the Three Gorges Reservoir area with different management treatments, including shrubs-cutting plus residue removal, harvest I (cutting intensity 15%, stem-only harvesting without residue removal), harvest II (cutting intensity 70%, harvest type as harvest I) and the control, were surveyed to measure the total soil respiration rates over a year by using LI-8100 system. The influence of various forest managements on soil respiration was discussed and the reasons causing the variability of soil respiration were analyzed. The results showed that: the annual soil respiration of forests with different treatments was1.82±0.07 μmol·m-2 s-1 (shrubs-cutting), 2.18±0.05 μmol·m-2 s-1 (control), 2.37±0.07 μmol·m-2s-1 (harvest I), and 2.86±0.1 μmol·m-2s-1(harvest II). The harvest intensity was positively related to soil respiration increment; soil respiration of all the harvest treatment reached the maximum in July and August. High intensity improved the soil temperature and moisture. The temperature sensitivity indexes of the control, shrubs-cutting, harvest I, and harvest II were 2.18±1.09, 1.65±0.07, 2.20 ±0.09 and 2.36±0.09 respectively.
