适用于杭州园林景观的珍稀濒危植物评价与筛选

Evaluation and Screening of Rare and Endangered Plants Applicable to Hangzhou Landscape Architecture

杭州植物园对于珍稀濒危植物种质资源的保存和扩繁是根据《国家重点保护野生植物名录(2021)》《国家重点保护野生植物》进行开展,挑选了目前保存和繁育的珍稀濒危植物100种,为了进一步筛选出适宜杭州市环境气候的珍稀濒危植物,使用层次分析法(AHP)对其进行了综合评价并构建了综合评价体系。其中,珙桐、银缕梅等10种珍稀濒危植物为第一层级,南方红豆杉、浙江楠等27种植物为第二层级,水松、鸡麻等43种植物为第三层级,山核桃、粗榧等为第四层级。选优了10种具有较好适应性的观赏珍稀濒危植物,为之后开展进一步工作提供理论基础和数据支持。The preservation and expansion of rare and endangered plant germplasm resources in Hangzhou Botanical Garden are carried out according to the National Key Protected Wild Plant List (2021) and the National Key Protected Wild Plants. 100 rare and endangered plants currently preserved and bred were selected. In order to further screen for rare and endangered plants suitable for the environmental climate of Hangzhou, the Analytic Hierarchy Process (AHP) was used to comprehensively evaluate them and a comprehensive evaluation system was constructed. Among them, 10 rare and endangered plants such as Gongtong and Silver Witch Plum are at the first level, 27 plants such as Southern Taxus and Zhejiang Nan are at the second level, 43 plants such as Water Pine and Chicken Ma are at the third level, and walnut and Chinese torreya are at the fourth level. 10 ornamental rare and endangered plants with good adaptability were selected to provide theoretical basis and data support for further work in the future.
