就南京、杭州两地的鸢尾属观赏植物资源及园林应用特点进行了调查研究。结果显示,两地在运用的植物种类以及应用特点上有着基本的一致性,但在应用的频度以及方式上有着明显的差异性。最后,对两地鸢尾属植物在园林应用中存在的问题提出建议,为今后在园林绿化建设和园林设计中合理利用鸢尾属资源,创造丰富多彩的园林景观提供思路。 The characteristics of Iris ornamental plant resources and garden application in Nanjing and Hangzhou were investigated. The results showed that there was a basic consistency in the types of plants and their application characteristics between the two places, but there were obvious differences in the frequency and manner of application. Finally, I put forward some suggestions on the existing problems of Iris plants in the garden, and provide ideas for rational utilization of Iris resources and creation of rich and colorful landscapes in landscape construction and landscape design in the future.
