Abstract

【Purpose】Urban green spaces mitigate carbon emissions, boost carbon sinks, and address environmental risks. Analyzing their types, carbon stocks, and key tree species' sequestration capacity aids in improving green space management. This advances the "Carbon Peak, Carbon Neutral" strategy, guiding greening industry development and robust ecosystem construction.【Method】A systematic survey was conducted at representative urban green space sites, establishing observation plots to study species composition and woody plant populations. The carbon sequestration capacity of major tree species was evaluated considering baseline carbon stock and a latitude correction parameter.【Result】The total carbon stock in Suqian's urban green spaces stands at 136,285.47 tons, with regional green spaces contributing the most, followed by parks and protective green spaces, while subsidiaries account for the least. Analysis reveals that the arbor layer is the primary carbon pool, surpassing soil, shrub, and herb layers. Notably, different arbor species exhibit significant variations in carbon sink capacity. There is an obvious difference in the carbon sink capacity of different tree species, and among the 30 major tree species in Suqian City, there is an obvious difference in the carbon sink capacity of different tree species, and there is an obvious difference in the carbon sink capacity of different tree species，Populus adenopoda, Populus × canadensis, Cedrus deodara, Triadica sebifera, Celtis julianae, Celtis sinensis, Liquidambar formosana, Malus spectabilis, Ligustrum lucidum, Acer buergerianum, Osmanthus fragrans, Metasequoia glyptostroboides, Ginkgo bilobaet al. Carbon sink capacity is weaker, and the carbon sink capacity of species will not be insignificantly related to the length of the time interval, but will be affected by the latitudinal zonal space。【Conclusion】 For urban green space management, trees are pivotal, dominating carbon sequestration potential compared to shrubs and herbs. Thus, studying carbon sequestration and oxygen release of tree communities is crucial. Additionally, attention should be given to tree configuration and species selection, prioritizing locally adapted, high-carbon sequestration trees while considering landscape aesthetics and biodiversity conservation, for efficient urban green space management.

Abstract

Wood‐decay macrofungi play a vital role in forest ecosystems by promoting nutrient cycling and soil structure, and their evolution is closely related to their host plants. This study investigates the potential evolutionary adaptation of wood‐decay macrofungi to their host plants, focusing on whether these relationships differ between gymnosperms and angiosperms. While previous research has suggested non‐random associations between specific fungi and plant deadwood, direct evidence of evolutionary adaptation has been lacking. Our study, conducted in a subtropical region, utilized metabarcoding techniques to identify deadwood species and associated fungi. We found significant evidence of evolutionary adaptation when considering all sampled species collectively. However, distinct patterns emerged when comparing angiosperms and gymnosperms: a significant evolutionary adaptation was observed of wood‐decay macrofungi to angiosperms, but not to gymnosperms. This variation may be due to the longer evolutionary history and more stable species interactions of gymnosperms, as indicated by a higher modularity coefficient (r =.452), suggesting greater specialization. In contrast, angiosperms, being evolutionarily younger, displayed less stable and more coevolving interactions with fungi, reflected in a lower modularity coefficient (r =.387). Our findings provide the first direct evidence of differential evolutionary adaptation dynamics of these fungi to angiosperms versus gymnosperms, enhancing our understanding of forest ecosystem carbon cycling and resource management.
