In order to realize precise regulation and control of urban carbon sequestration and emission reduction,Dongguan City was taken as the research area,and an optimization framework of carbon metabolism pattern was constructed for predicting the carbon emission at the macro level and enhancing the urban carbon sequestration capacity at the medium and micro levels.Carbon emissions in energy consumption predicted by LEAP model scenarios were applied to urban land use types,and urban carbon sequestration potential areas predicted by LANDIS model were added.the weak areas of urban carbon metabolism in the future were identified,and then the optimization idea of urban carbon metabolism pattern was put forward.The results show that:l)The energy consumption in Dongguan City in future deviates from the carbon emission target,and the emission reduction scenario is more in line with the actual social and economic development than the high-limit scenario,so,energy conservation and emission reduction should be done from the industrial demand side.2)The carbon sequestration potential of Dongguan is relatively limited.Under the emission reduction scenario,there are only 9 nodes for increasing sinks.The carbon sequestration and emission reduction need to be guaranteed by constructing ecological corridor network framework,setting carbon emission expanding belt,and restorating the ecological base.3)The key to realizing the optimization of carbon metabolism pattern by Leap-Landis in future is to apply the carbon emissions of energy consumption predicted by LEAP model to the urban land use pattern.
