| 城市生物多样性与人类生活密切相关，而校园植物是其中的重要一环。本研究统计了39个中国高校校园的完整植物名录，并对其进行区域划分，进而研究各区域内校园植物的多样性和区域间植物组成的相似性。此外，我们还选取了两个常见行道树分布的科——樟科（Lauraceae）和杨柳科（Salicaceae），分析它们在不同纬度校园间分布的差异性。结果显示，我国南方地区校园植物的多样性较高，但各区域间较为相似，相似性系数在0.675~0.721；北方地区的校园植物虽然丰富度较低，但各区域间的差异较大，相似性系数在0.417~0.609。与东、西部地区相比，同纬度中部地区的校园植物特异性较低。樟科植物的丰富度从南向北依次递减，杨柳科植物的种丰富度从南向北依次递增。地理环境和气候因素导致了这些差异的形成。这些信息有助于各地校园合理配置植物，并将为各地区城市生态系统的管理提供参考。 |

| Abstract: |
| Urban biodiversity is closely related to the human life， and the campus plants are important part of it. We collected the complete plant lists of 39 Chinese university campus in different regions， and studied the diversity and similarity of campus plants among these regions. In addition， we also selected two common street tree distribution families， Lauraceae and Salicaceae， and analyze their distribution differences between different latitudes. Results show that plants in the south Chinese campus have a higher species diversity， but are more similar among different regions， the similarity coefficient is 0.675~0.721. While campus plants in the northern area have a lower abundance， but show greater differences between various regions， the similarity coefficient is 0.417~0.609. Compared with plants in east and west regions of the same latitude， the campus plant specificity in the central regions is lower. The richness of Lauraceae decreases successively from south to north， while the species richness of Salicaceae increases successively from south to north. These differences are caused by geographical and climatic factors. The information in this study can help campus horticulturist in China allocate plants rationally， and will provide references for the regional urban ecosystem management. |
