城市绿化中植物配置与生态效应分析
摘 要
城市绿化作为改善城市生态环境的重要手段，其植物配置的合理性直接影响到生态效应的发挥。本研究旨在探讨不同植物配置对城市绿化生态效应的影响，并提出优化策略。研究背景基于当前城市化进程中，绿地面积减少和生态环境恶化的问题日益突出。通过文献综述和实地调查，本研究选取了北京、上海、广州等典型城市的多个绿化项目进行分析。采用定量与定性相结合的方法，包括植物多样性指数、生态系统服务价值评估等，系统评估了不同植物配置下的生态效应。结果显示，混合种植模式相较于单一树种种植模式，显著提高了生物多样性和生态系统服务功能。具体而言，混合种植模式下的绿地能够更好地调节气候、净化空气和提供休闲娱乐空间。此外，研究发现本地植物的应用在提升生态效应方面具有显著优势。基于此，本研究提出了以本地植物为主导的混合种植策略，并结合实际案例进行了验证。

ANALYSIS OF PLANT CONFIGURATION AND ECOLOGICAL EFFECT IN URBAN GREENING
ABSTRACT
As an important means to improve the urban ecological environment, the rationality of the urban greening plant allocation directly affects the play of the ecological effect. The aim of this study was to investigate the effects of different plant configurations on the ecological effects of urban greening and propose optimization strategies. In the process of urbanization, the reduction of green space area and ecological environment deterioration are increasingly prominent. Through literature review and field investigation, several greening projects in Beijing, Shanghai, Guangzhou were selected. Combining quantitative and qualitative methods, including plant diversity index and value assessment of ecosystem services, we systematically evaluated the ecological effects under different plant configurations. The results showed that the mixed planting model significantly improved the biodiversity and ecosystem service function compared with the single tree planting model. Specifically, the green space under the mixed planting mode can better regulate the climate, purify the air and provide leisure and entertainment space. Moreover, it study found that the application of native plants has significant advantages in enhancing ecological effects. Based on this, this study proposed a mixed planting strategy dominated by native plants and verified it with real cases.
