[Objective] The effects of rural land reclamation on CO₂ emission were analyzed to provide reference for relevant research in carbon emission.[Methods] Based on the project budget, the CO₂ emission was estimated and the key impacting factors were analysed using IPCC inventory methods. Scenarios of CO₂ emission changes in rural land reclamation under different policies were simulated and regulations of low carbonization land reclamation were proposed.[Results] The result showed that the total CO₂ emission of this project was estimated to be about 5.50×10⁵ t, the engineering works of irrigation and drainage had the largest proportion. The cement was the main carbon source, accounting for 92.07% of total emissions. The CO₂ emission of carbon source materials directly depended on the CO₂ emission coefficient and consumption of this materials, indirectly depended on the quantities and structure of the projects. With the implement of relevant emission reduction policies, CO₂ emissions would be reduced.[Conclusion] It is concluded that the concept of green, low carbon, environmental protection should be implemented in rural land reclamation planning and design, and the ecological effect of it should be more attention to. Energy conservation and emissions reduction for those energy intensive industries such as cement, electricity and steel, should be enhanced, and in these fields, national emission reduction policies should be implemented strictly.
