城市绿地中园林植物群落结构对生物多样性的影响研究

Research on the Impact of Garden Plant Community Structure in Urban Green Spaces on Biodiversity

摘要: 随着城市化进程以前所未有的速度推进，城市绿地作为城市生态系统不可或缺的关键组成部分，在维系生态平衡、提升城市环境品质、推动生物多样性保护等方面发挥着无可替代的核心作用。园林植物群落作为城市绿地的核心构成要素，其结构特征犹如生态系统的“骨架”，不仅直接决定生物多样性水平，更深远影响着整个城市生态系统的稳定性与可持续发展能力。本文综合运用理论分析与实证研究相结合的方法，深入剖析城市绿地中园林植物群落结构对生物多样性的影响机制，旨在揭示植物群落结构特征(涵盖物种组成、空间配置、层次结构等多个维度)与生物多样性之间的内在关联，从而为城市绿地科学规划与合理设计提供坚实的理论支撑和实践指导。

Abstract: With the urbanization process advancing at an unprecedented pace, urban green spaces, as an indispensable key component of the urban ecosystem, play an irreplaceable core role in maintaining ecological balance, enhancing the quality of the urban environment, and promoting the conservation of biodiversity. As the core constituent element of urban green spaces, the structural characteristics of garden plant communities are like the “skeleton” of the ecosystem, directly determining the level of biodiversity and profoundly influencing the stability and sustainable development capacity of the entire urban ecosystem. This paper comprehensively employs a method combining theoretical analysis and empirical research to deeply analyze the influence mechanism of the structure of garden plant communities in urban green spaces on biodiversity, aiming to reveal the intrinsic connection between the structural characteristics of plant communities (covering multiple dimensions such as species composition, spatial configuration, and hierarchical structure) and biodiversity, thereby providing solid theoretical support and practical guidance for the scientific planning and rational design of urban green spaces.
