城市植物为人类福祉提供各种生态系统服务和生物多样性。有必要研究植物种类和功能性状的构成及其影响因素。以北京市建成区8种土地利用类型绿地为研究对象，采用棋盘格随机样地法对绿地植物种类和功能性状的变异性进行了研究。结果表明，北京市建成区木本植物中外来种85种（57%），花粉致敏种21种（14%），抗性种99种（67%）。住宅区，社区公园和机构领域有较高的木本植物物种丰富度比其他LUT。本地种和外来种分布较广。除了抗寒和抗旱性外，具有抗性的物种比例较低;因此，高强度的管理和维护对于该城市地区植物的生存至关重要。在不同的土地使用单位中，选择对恶劣条件有抵抗力的植物品种时应谨慎。房价、距市中心距离、建地年限和绿化率与植物功能性状和物种多样性有较强的相关性。城市森林管理者应考虑植物的功能特性和LUT的具体战略，以最大限度地提高森林和人类的健康。
Urban plants provide various ecosystem services and biodiversity for human well-being. It is necessary to examine the plant species and functional traits composition and the influencing factors. In this study, a field survey was conducted using the tessellation-randomized plot method to assess the plant species and functional traits variability in greenspaces across eight land use types (LUTs) in the built-up areas of Beijing, China. Results showed that the woody plants in the built-up areas of Beijing comprised 85 non-native species (57%), 21 pollen-allergenic species (14%), and 99 resistant species (67%). Residential areas, community parks and institutional areas had higher woody plant species richness than other LUTs. Native and extralimital native species were more widespread than exotic species. Proportions of species with resistances were low except for cold- and drought-resistance; consequently, a high intensity of management and maintenance is essential for survival of plants in this urban area. Caution should be exerted in selecting plant species with resistance to harsh conditions in different LUTs. Housing prices, distances from the urban center, years since the establishment of LUTs and greening rate were strongly correlated with the plant functional traits and species diversity. Urban forest managers should consider plant functional traits and LUT-specific strategies to maximize both forest and human health.
