广州下沉式绿地草本植物应用综合评价

对广州市主城区9处下沉式绿地植物种类及其配置进行调研,采用AHP层次分析法,从植物生长势、观赏性2个方面的11个主要指标,来构建植物综合评价模型,结合文献资料进行综合评价。在34种草本植物中筛选出生长势强、观赏性好、抗倒伏、虫害少等优良性状的8种植物:芦竹(Arundo donax)、狗尾草(Setaria viridis)、玉蝉花(Iris ensata)、花叶艳山姜(Alpinia zerumbet)、黄菖蒲(Iris pseudacorus)、翠芦莉(Ruellia brittoniana)、鹤望兰(Strelitzia reginae)和山菅(Dianella ensifolia),建议将此优势种类作为广州下沉式绿地建设的优先选择植物。此外,还分别针对不同类型下沉式绿地给出植物配置建议。

Comprehensive Evaluation of the Application of Herbaceous Plants in Guangzhou Sunken Green Space

In this paper, the plant species and their configuration of sunken green space in six key built-up areas in Guangzhou were investigated and the analytic hierarchy process (AHP) was used to construct the relevant plant evaluation model from the growth potential and ornamental characters. By comparing the leaf rate, lodging rate, pest rate, new tender leaf potential and growth competitiveness, combined with their ornamental data, 8 excellent species: Arundo donax, Setaria viridis, Iris ensata, Alpinia zerumbet, Iris pseudacorus, Ruellia brittoniana, Strelitzia reginae, and Dianella ensifolia were selected from 34 herbaceous plants with a view to offering references for plant selection and community allocation in sunken green space.
