The optimization of carbon metabolism through land use/cover change and spatial adjustment has been the focus of sustainable development in urban areas. Under the framework of urban metabolism, this paper includes a comprehensive review of carbon metabolic process accounting, ecological network analysis of urban carbon metabolism, the relationship between carbon metabolism and land use/cover change, and the spatial patterns of carbon metabolism. This paper summarizes the insufficiencies of current research, including insufficient spatial analysis of the network of carbon metabolism, limitations to practical application of carbon budget and modeling results, and the disparity between natural and social-economic activities in the same system. Finally, future needs in research are proposed:1) A spatially explicit network model of urban carbon metabolism should be built within the perspective of land use/cover change. The model should investigate network flows, using carbon emission and sequestration accounting results, which could represented the carbon storage of the biosphere. Then, the flows between any two nodes of the network could be deduced by accounting for changes in storage. The spatial expression of the interaction between any two nodes could be explored using the model. 2) The model should also focus on natural activities in the urban metabolic system. The network model should include both natural and socio-economic nodes and should be constructed to support urban planning. 参考文献 相似文献 引证文献
