Abstract:: In order to study the effects of land consolidation on carbon emissions, this paper took the land consolidation project in Julu Conty of Hebei Provimec as the study area, and analyzed the carbon emission caused by the energy consumption in land leveling, irrigation and drainage, road construction, farmland protection and land use type changes based on energy consumption and land use change theory and using carbon emission inventory methods. We made clear the land consolidation carbon source or sink effect and its calculation methods. And suggestions of low carbonization land consolidation were put forward in order to provide scientific reference on researching carbon emissions of land consolidation. The result shows that the total carbon emission resulting in energy consumption is 303.87 t. The land leveling project is the major source of carbon emission, accounting for 64.53% of total carbon emissions of engineering construction, the road engineering and irrigation and drainage engineering accounting for 30.24% and 5.23%. The maximum value of the proportion investment quantity carbon emissions and proportion investment volume of carbon emission rate is land leveling project, respectively of 677.87 kg/10 000 yuan. and 10.02, indicating that the project has the characteristics of less investment and low carbon emission. The minimum value is irrigation and drainage engineering, it has the characteristics of large investment and low carbon emissions. Land consolidation of Julu County made regional vegetation and soil carbon storage decrease by 4 160.3 t caused by land use type change, presenting the effect of carbon source. According to the environment economic cost-benefit analysis method, land consolidation area carbon emissions of Julu County is equivalent to 4 464.17 t, the per unit area of carbon emission is 1 966.52 kg/hm², the unit investment of carbon emission is 994.19 kg/10 000 yuan.
