[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.
