摘 要
城市化进程加速导致园林植物多样性面临威胁，同时景观质量亟待提升。本研究旨在探讨城市园林植物多样性保护与景观优化的协同路径，以实现生态效益与美学价值的统一。研究选取典型城市绿地为样本，通过实地调查、遥感分析与物种多样性评估等方法，系统分析了植物群落结构特征及其对景观功能的影响。结果表明，当前城市园林植物种类单一化趋势明显，外来物种引入比例较高，且乡土植物资源未得到充分挖掘和利用。基于此，研究提出构建多层次植物配置模式，并结合生态修复技术提升绿地综合效能。创新点在于将植物多样性保护融入景观设计全过程，提出了“功能性-美学性”双导向的优化策略。该研究为城市园林规划提供了科学依据，有助于推动可持续城市发展目标的实现。

Abstract
The accelerating urbanization process has posed threats to the diversity of landscape plants and highlighted the urgent need for improving landscape quality. This study aims to explore the synergistic pathways for conserving urban landscape plant diversity and optimizing scenic environments, thereby achieving the integration of ecological benefits and aesthetic values. Typical urban green spaces were selected as samples, and their plant community structure characteristics and impacts on landscape functions were systematically analyzed using field surveys, remote sensing analysis, and species diversity assessments. The results indicate a significant trend towards homogenization in urban landscape plant species, a high proportion of introduced species, and insufficient utilization of native plant resources. Based on these findings, this study proposes the establishment of multi-layered plant configuration models combined with ecological restoration techniques to enhance the overall efficiency of green spaces. An innovative aspect of this research is the integration of plant diversity conservation into the entire process of landscape design, proposing a dual-oriented optimization strategy focusing on functionality and aesthetics. This study provides a scientific basis for urban landscape planning and contributes to the realization of sustainable urban development goals.
