园林植物群落构建与生物多样性保护研究 -园林专业

摘要

园林植物群落构建与生物多样性保护密切相关，随着城市化进程加快，城市绿地成为维护生物多样性的重要载体。本研究旨在探索园林植物群落构建对生物多样性保护的影响及优化路径，以期为城市生态建设提供理论依据。合理的植物群落构建能够显著提高物种丰富度和均匀度，促进不同营养级生物间的协同进化，形成稳定而高效的生态系统。创新性地提出基于本地物种优先原则的群落构建模式，强调自然演替过程中的人为干预应遵循生态规律，避免外来物种入侵造成的生态风险。该模式不仅有助于维持较高的生物多样性水平，还可在景观美学价值提升方面发挥积极作用，为实现城市可持续发展目标提供了新思路。此外，研究发现不同类型绿地在生物多样性保护功能上存在差异，建议根据不同区域特点制定个性化群落构建方案，以达到最佳生态效益。本研究深化了对园林植物群落构建机制的理解，为城市绿地规划管理提供了科学指导，具有重要的理论意义和实践价值。

Construction of Landscape Plant Communities and Biodiversity Conservation

ABSTRACT

The construction of garden plant community is closely related to the conservation of biodiversity. With the acceleration of urbanization, urban green space has become an important carrier to maintain biodiversity. The purpose of this study was to explore the impact of garden plant community construction on biodiversity conservation and its optimization path, in order to provide theoretical basis for urban ecological construction. Reasonable plant community construction can significantly improve the richness and uniformity of species, promote the co-evolution of organisms of different trophic levels, and form a stable and efficient ecosystem. An innovative community construction model based on the principle of native species priority was proposed, emphasizing that human intervention in the process of natural succession should follow the ecological law to avoid the ecological risk caused by the invasion of alien species. This model not only helps to maintain a high level of biodiversity, but also plays a positive role in enhancing the aesthetic value of landscape, providing a new way to achieve the goal of urban sustainable development. In addition, the study found that different types of green space have different functions in biodiversity conservation, and it is suggested to formulate personalized community construction schemes according to different regional characteristics to achieve the best ecological benefits. This study deepens the understanding of the mechanism of garden plant community construction, provides scientific guidance for urban green space planning and management, and has important theoretical significance and practical value.
