摘 要
城市园林绿化是提升城市生态环境质量的重要手段，植物多样性保护与利用在其中发挥着关键作用。本研究旨在探讨城市园林绿化中植物多样性的现状、面临的问题及优化策略，通过实地调查、文献分析和案例研究相结合的方法，选取典型城市区域进行深入调研。研究发现，当前城市园林绿化存在植物种类单一、外来物种入侵风险增加、本土植物资源利用率低等问题。通过对不同绿化模式的对比分析，提出构建多层次、多类型的植物群落结构，强调本土植物的应用价值，建立科学合理的植物配置体系。研究创新性地引入生态适应性评价模型，为植物选择提供量化依据，同时提出基于生态系统服务功能的植物多样性保护框架，为城市园林绿化的可持续发展提供了理论支持和技术指导，有助于实现城市生态系统的稳定性和生物多样性保护目标。

ABSTRACT
Urban landscaping is a critical approach to enhancing the ecological environment quality of cities, with plant diversity protection and utilization playing a pivotal role. This study aims to investigate the current status, challenges, and optimization strategies of plant diversity in urban landscaping through a combination of field surveys, literature analysis, and case studies, focusing on typical urban areas for in-depth research. The findings reveal that current urban landscaping practices suffer from issues such as limited plant species diversity, increased risks of invasive alien species, and low utilization rates of native plant resources. By comparing different greening models, this study proposes the construction of multi-layered and multi-typed plant community structures, emphasizing the application value of native plants and establishing a scientifically sound plant configuration system. Innovatively, an ecological adaptability evaluation model is introduced to provide quantitative criteria for plant selection, while a plant diversity conservation fr amework based on ecosystem service functions is proposed. These contributions offer theoretical support and technical guidance for the sustainable development of urban landscaping, contributing to the stability of urban ecosystems and the achievement of biodiversity conservation ob jectives.
