英文摘要A series of ecological projects, including forest and dike-pond projects, were constructed in the littoral zone of the Three Gorges Reservoir (TGR) to maintain the ecological safety of this area. Previous ecological designs mainly focused on the functions of ecological engineering for environmental purification, economic value and increased biodiversity. However, the variations in land-use may alter the emissions of greenhouse gases (GHGs), which were ignored in our previous design. In this paper, the carbon sequestration benefits of ecological engineering were evaluated after dynamically monitoring the GHG emissions from different land-use sites during the growing (April-September) and submerged (October-March) seasons. The results showed that CH4 fluxes in the dike-ponds (3.76 CH4-mg m(-2) h(-1)) and rice paddies (6.09 +/- 1.60 mg-CH4 m(-2) h(-1)) were significantly higher than those in the natural littoral zone (0.77 +/- 0.27 mg-CH4 m(-2) mg-CH(4)m(-2) h(-1)) and forest project (0.57 +/- 0.31 mg-CH4 m(-2) h(-1)) during the growing season. There were no significant differences in the CO2 fluxes from different land-use sites. The emission of N2O from different land-use sites was low and ranged from -0.02 to 0.07 mg-N2O m(-2) h(-1). The growing season contributed to more than 76% of the cumulative annual GHG emissions. Direct GHG emissions and the carbon sequestration ability of species determined the net carbon sinks in the littoral zone. Net carbon sinks in the forest projects with different understory plant communities showed a small variation, with a range of -2.58 to 3.40 t-CO2 ha(-1) year(-1), but the design of the dike-pond projects should favor species that are positive net carbon sinks, e.g., Sagittaria (19.76 t-CO2 ha(-1) y(-1)) and Canna generalis (16.79 t-CO2 ha(-1) y(-1)), rather than those that are negative net carbon sinks, e.g., Trapa natans (-11.79 t-CO2 ha(-1) y(-1)).
