Abstract

The factors influencing urban plant diversity in tropical cities remain underexplored. To address this gap, we conducted comprehensive field surveys and remote sensing analyses in Danzhou, Hainan Province, focusing specifically on urban functional units. Our study quantified the diversity of trees, shrubs, herbaceous plants, spontaneous species, and cultivated species, employing spatial autocorrelation analysis to assess their relationships with land cover, socioeconomic factors, greening management practices, and landscape patterns. Our results revealed that recreational and leisure areas contained the highest proportions of urban green space, while transportation zones had the lowest. Herbaceous plants were predominant across key urban functional units, and cultivated species consistently outnumbered spontaneous species. Notably, the richness of tree species correlated positively with the age of urban construction, indicating a legacy effect. Additionally, effective greening management practices, such as watering and fertilization, were essential for enhancing plant diversity, and landscape pattern indices significantly affected species richness. These findings provide valuable insights for managing urban plant diversity in Danzhou and contribute to the understanding of the driving factors behind plant diversity in tropical urban environments.

儋州市绿化管理与景观格局对城市绿地植物多样性的影响

热带城市植物多样性的影响因素尚未得到充分的研究。为了解决这一差距，我们在海南儋州进行了全面的实地调查和遥感分析，特别关注城市功能单元。本研究量化了乔木、灌木、草本植物、自然物种和栽培物种的多样性，采用空间自相关分析评估了它们与土地覆盖、社会经济因素、绿化管理实践和景观格局的关系。结果表明，休闲娱乐区城市绿地占比最高，交通运输区城市绿地占比最低。草本植物在城市主要功能单元中占主导地位，栽培物种数量持续超过自然物种。值得注意的是，树种丰富度与城市建设年龄呈正相关，表明存在遗留效应。此外，有效的绿化管理措施（如浇水和施肥）对提高植物多样性至关重要，景观格局指数对物种丰富度有显著影响。这些发现为儋州城市植物多样性的管理提供了有价值的见解，并有助于了解热带城市环境中植物多样性的驱动因素。

期刊介绍： Urban Forestry and Urban Greening is a refereed, international journal aimed at presenting high-quality research with urban and peri-urban woody and non-woody vegetation and its use, planning, design, establishment and management as its main topics. Urban Forestry and Urban Greening concentrates on all tree-dominated (as joint together in the urban forest) as well as other green resources in and around urban areas, such as woodlands, public and private urban parks and gardens, urban nature areas, street tree and square plantations, botanical gardens and cemeteries. The journal welcomes basic and applied research papers, as well as review papers and short communications. Contributions should focus on one or more of the following aspects: -Form and functions of urban forests and other vegetation, including aspects of urban ecology. -Policy-making, planning and design related to urban forests and other vegetation. -Selection and establishment of tree resources and other vegetation for urban environments. -Management of urban forests and other vegetation. Original contributions of a high academic standard are invited from a wide range of disciplines and fields, including forestry, biology, horticulture, arboriculture, landscape ecology, pathology, soil science, hydrology, landscape architecture, landscape planning, urban planning and design, economics, sociology, environmental psychology, public health, and education.
