摘 要
植物多样性在园林景观设计中扮演着至关重要的角色，其对景观稳定性的影响已成为生态学和景观设计领域的研究热点。本研究旨在探讨不同植物多样性水平对园林景观稳定性的具体影响，并通过实验和数据分析揭示其内在机制。研究背景基于当前城市化进程中园林景观面临的生态挑战，如生物多样性下降和生态系统服务功能减弱。为此，我们选取了多个具有不同植物多样性水平的园林作为研究对象，采用定量分析和实地观测相结合的方法，系统评估了植物多样性与景观稳定性之间的关系。较高的植物多样性显著提升了园林景观的稳定性，主要体现在土壤肥力、水分保持能力和病虫害抵抗能力等方面。具体而言，植物多样性通过促进土壤微生物群落的丰富度和活性，增强了土壤养分循环和水分利用效率；同时，多样的植物种类能够有效分散病虫害压力，减少单一物种遭受病害的风险。此外，本研究发现，植物多样性还对园林景观的美学价值和社会效益产生了积极影响，如提升游客满意度和促进社区参与度。

Abstract
Plant diversity plays a crucial role in landscape design, and its influence on landscape stability has become a research hotspot in the field of ecology and landscape design. The aim of this study was to investigate the specific effects of different levels of plant diversity on the landscape stability and to reveal the intrinsic mechanisms through experiments and data analysis. The research background is based on the ecological challenges faced by landscape landscapes in the current urbanization process, such as declining biodiversity and weakened ecosystem services. To this end, we selected multiple gardens with different levels of plant diversity, and evaluated the relationship between plant diversity and landscape stability systematically using a combination of quantitative analysis and field observations. High plant diversity significantly improves the stability of the landscape, mainly reflected in soil fertility, water retention, and pest resistance. Specifically, plant diversity enhances soil nutrient cycling and water use efficiency by promoting the richness and activity of soil microbial communities, and diverse plant species can effectively disperse pest stress and reduce the risk of disease in a single species. Furthermore, this study found that plant diversity also has a positive impact on the aesthetic value and social benefits of the landscape, such as enhancing visitor satisfaction and promoting community participation.
