摘　　要：运用景观生态学原理，在对越秀公园植被景观要素进行分类的基础上，运用Autocad软件提取了景观要素斑块信息，选取了斑块数目、斑块数目比、斑块面积、斑块面积比、斑块密度指数、斑块形状指数、优势度、分维度、均匀度等9个指标对越秀公园植被景观的多样性、异质性、均匀性及破碎化程度等景观格局进行了分析。结果表明：越秀公园植被景观整体布局基本合理，景观结构较为稳定，密林作为全园的基质，保持了较好的生态完整性和连续性，为越秀公园的整体景观与环境提供了良好的基础生态条件，但需对部分景区植被景观布局作相应调整。同时对越秀公园植被景观整体格局优化和生态完善建设提出了建议。Based on classified patch types of the vegetation landscape of Yuexiu Park according to the landscape ecology theory, this study analyzed the vegetation landscape pattern of Yuexiu Park by selecting nine landscape pattern indexes such as patch number, patch number ratio, patch area, patch area ratio, patch density index, patch shape index, dominance, fi＇actal dimension and evenness after obtaining the patch information on the support of Autocad. The results showed that the vegetation landscape pattern of Yuexiu Park was generally rational, and the landscape structure was generally stable. Flourish hurst patches, the matrix of the overall vegetation landscape, were better integrated, which provided a good condition to the overall environment of Yuexiu Park, but the pattern of some areas still needed to improve. Besides, suggestions on optimizing the vegetation landscape pattern and ecological construction of Yuexiu Park were put forwarded in this paper.
