Abstract:It is of great importance to study the carbon metabolism of the production-living-ecological space (PLES) for the integration of various elements and the structural adjustment in PLES. Taking Tangshan city as an example, this paper tracks and evaluates the carbon flow in the PLES from 2010 to 2015. It is indicated that the net carbon flow of the PLES in Tangshan is negative from 2010 to 2015, and the evolution of the PLES increases the carbon emission. The negative carbon flow is caused by the transformation from the Ecological Space to the Production Space while the positive carbon flow is due to the reverse transformation between the Ecological Space and the Production Space. In addition, the ecological relation of the carbon metabolism in Tangshan is mainly to limit the predatory relation, with the urban and the unutilized lands as the main part.
