| 当前城市化发展迅速，生物多样性日益受到威胁，城市绿地植物群落稳定性差，将直接影响其生态功能的发挥。对城市绿地植物群落的主要生态功能、稳定性及其关系进行阐释，论述了生物多样性影响群落稳定性的生物途径和非生物途径。在已有关于城市街区尺度生物多样性指标的研究基础上，提出城市绿地植物群落构建的原则，并基于生物多样性对城市绿地植物群落稳定性的作用机制，总结了高稳定性城市绿地植物群落的构建方法：1）从生物途径，选择具有优势性状的物种，选择可保证多种性状协同发展的结构和物种搭配；2）从非生物途径，选择合适的、抗干扰能力强的植物群落结构、物种及立地条件，为动植物构建适宜的小生境，同时实现群落中动植物对资源的高效利用。以期为中国城市绿地生态效能提升及植物群落的构建提供方法参考。 |

| Abstract: |
| With the rapid development of urbanization, biodiversity is increasingly threatened, and the poor stability of urban green plant communities will directly affect the performance of its ecological functions. It also directly affects the self-regulation of urban ecological functions. This research briefs the main ecological functions, stability and relationship of the urban green space plant communities, and explores the biological and non-biological pathways through which biodiversity affects the stability of the communities. Based on the existing researches on biodiversity indicators at the urban block scale, it proposes the principles for constructing urban green space plant communities, and based on the mechanism of biodiversity affecting the stability of urban green space plant communities, sums up the ways of constructing highly stable urban green space plant communities. 1) From the biological approach, it selects the species with dominant traits, and the structures and species collocations that can ensure coordinated development of multiple traits. 2) From the non-biological approach, select the appropriate and strong anti-interference structure, species and site conditions to build a suitable niche for animals and plants, and at the same time realize the efficient use of resources for animals and plants in the community. The ultimate goal of this research is to provide a method reference for the improvement of the ecological efficiency of urban green space and the construction of plant communities in China in the future. |
