“…From a network perspective, it is possible to identify and quantify the characteristics of spatial and temporal carbon flow exchange resulting from land use changes. This approach helps identify the processes associated with carbon stock increases and decreases, enabling a better understanding of how to balance the carbon budget and promote sustainable urban development [10][11][12]. Researchers are able to investigate how different land use patterns impact urban carbon neutrality during urbanization, and how they can be optimally adjusted to reduce or eliminate carbon metabolism disorders in cities.…”

Carbon-neutral growth is a crucial long-term climatic aim in the context of global warming. This paper introduces complex network theory and explores its potential application to achieve this goal. Specifically, we investigate the spatial and temporal distribution of nodes and sources in the ecological network, and examine whether a relationship between the topological index of network nodes and the landscape pattern index of ecological source areas exists. We also determine the contribution of nodes to the carbon stock of the entire network by exploring the correlation between the carbon stock of nodes and sources, in order to develop an optimization strategy based on the synergistic effect of node-source carbon enhancement. Finally, we test the effect of network optimization through robustness. Our results show that (1) The correlation topological feature index analysis reveals that the degree distribution of the node network's topological characteristics becomes dispersed and modular, exhibiting the characteristics of small-world networks according to a large clustering coefficient. The heterogeneity and extent of ecological source landscapes have increased by modularity index, but remain distributed and locally fragmented. (2) According to correlation analysis, by enhancing the eccentricity of the node topology, the patch cohesion index (COHESION) of the ecological source site can maximize the contribution of the node to the enhancement of the carbon stock benefits of the source site. (3) According to the tests on the robustness of nodes and edges, and the robustness of network links, network stability is improved and carbon sink capacity is enhanced. Simultaneously, the restoration and rejuvenation of ecological space through national ecological construction projects can effectively improve the carbon sink within the organised region, contributing to the carbon neutrality aim. This research gives scientific and quantifiable references for potential ecological construction projects for sustainable cities and the optimisation of urban ecological space structure.
