| 中文摘要: |
| 广场绿地作为城市绿地系统的重要组成部分,其植物配置不仅影响景观效果,也直接关系到城市碳汇功能的发挥。以郑州市19个典型广场绿地为对象,系统调查地上部分的植被群落结构及碳储量,分析优势树种现存格局及其与碳汇效应之间的关系。结果表明,郑州市广场绿地存在明显的树种配置趋同现象,冬青卫矛、小叶女贞、雪松等景观型树种在多个样地中高频共现,构成了景观主导型群落。仅有25%的优势树种同时具备较高的单株碳储量,反映出当前植物配置模式的碳汇功能相对有限。此外,碳储量受绿地面积、高大乔木比例、平均冠幅的显著影响,而植物多样性对碳储量的解释力相对较低。以期为城市绿地碳汇功能的提升提供科学依据,郑州市未来绿地建设应优先选择兼具景观价值与高碳汇能力的乡土树种。 |

| Square green spaces, as integral components of urban green infrastructure, play a critical role in both landscape aesthetics and carbon sequestration. This study systematically investigated the aboveground vegetation community structure and carbon storage of 19 typical square green spaces in Zhengzhou City, and
analyzed the existing patterns of dominant tree species and their relationship with carbon sequestration effects. The results revealed a pronounced pattern of tree species convergence, with landscape-oriented species such as Euonymus japonicus, Ligustrum quihoui, and Cedrus deodara frequently co-occurring across multiple sites, forming a landscape dominant community. However, only 25% of the dominant tree species exhibited high carbon sequestration capacity, reflecting the insufficient carbon sequestration function of the current plant configuration model. In addition, carbon storage was significantly influenced by green space
area, the proportion of tall arbors, and the average crown width, while plant diversity had relatively low explanatory power for carbon storage. This study provides scientific support for improving carbon sequestration capacity of urban green spaces. Native tree species with both high ornamental value and strong carbon sequestration capacity should be prioritized in future green space construction of Zhengzhou City. |
