Analysis of carbon emission structure of agricultural ecosystem - A case study of rural areas surrounding Yuqiao Reservoir in Ji County of Tianjin, China

With the development of low carbon economy, there is increasing interest in integrating the idea of low carbon into rural life and agricultural ecosystem. Determination of the main carbon sources from agricultural ecological system is an important basic work to reduce carbon emissions and construct the low carbon new countryside. In this paper seven towns surrounding Yuqiao Reservoir as investigation objects were used to determine the main carbon sources. It has been found that land respiration is the main carbon emission sources of agriculture ecosystem through calculation and analysis. Carbon emissions produced by the land respiration account for 51.68% of the total emission, followed by carbon emissions generated by the rural life, which account for 42.37% of the total emission. Control of land planting structure and use of low carbon new energy are the main direction of rural carbon emission reduction in the future.
