广州夏季花境植物资源调查与评价

Investigation and Evaluation of Plant Resources of Summer Flower Border in Guangzhou

摘要:

为筛选出适合广州夏季花境应用的植物，对广州花境植物资源展开实地调查，运用层次分析法，从观赏性、适应性和种植养护3个方面进行评价。结果表明：广州夏季花境应用频度较高的植物有80种，隶属于45科71属，筛选出其中16种观赏价值高、生态适应性强、养护管理投入少的Ⅰ级花境植物；在准则层中，观赏性的权重值最大，在指标层中，花色和花量的权重值较大，因此在花境的植物配置中应重视色彩设计；广州夏季应用的花境植物以一年生草本、多年生草本和灌木为主，乡土植物应用较少。

Abstract:

In order to screen out the plant suitable for summer flower border applications in Guangzhou, a field investigation of plant resources was carried out, and the Analytic Hierarchy Process(AHP) was used to evaluate from three aspects: ornamental, adaptability and planting maintenance. The results show that there are 80 species of flowering plants, belonging to 45 families and 71 genera, which are frequently used in summer landscape in Guangzhou. Among them, 16 species with high ornamental value, strong ecological adaptability and low maintenance and management input were screened out as class I flower border plants. In the criterion layer, the weight value of ornamental was the largest, and in the index layer, the weight value of flower color and flower quantity were larger, so the color design should be paid attention to in the plant configuration of the flower border. The flower border plants applied in Guangzhou in summer were mainly annual or biennial herbs, perennial herbs and shrubs, and the application of native plants were relatively few.
