合肥地区公园绿地林下植物调查应用分析

Investigation and application of understory plants in parks and green spaces in Hefei area

通过对研究区公园绿地林下植物实地勘察和调查统计,了解不同林分林下植物应用情况和特点、植物种类和应用频率,为林下植物景观营建和配置研究提供参考。结果表明,该区共有乔、灌木83种,分属于45科,以蔷薇科、忍冬科、小檗科和木樨科所属种应用较多;地被及藤本植物47种,分属于27科,以天门冬科、石蒜科、酢浆草科和鸢尾科所属种应用较多。公园绿地常见的林下灌木主要为海桐、杜鹃、金丝桃和石楠等,耐阴的地被植物多集中使用萱草、玉簪、大吴风草、鸢尾和石蒜等。本次调查表明,应加大耐阴植物发掘和引种力度,拓展其林下应用范围,重视增加研究区林下植物多样性、植物景观配置和层次结构的构建,提升城市林下景观效果。

Through the field investigation and statistics of the understory plants in the park green space in the study area,the application situation,characteristics,plant species and application frequency of different stands of the understory plants were studied,so as to provide references for the construction and allocation of the understory plant landscape.The results showed that there were 83 species,belonging to 45 families,of which Rosaceae,Caprifoliaceae,Berberidaceae and Oleaceae were more widely used.There were 47 species of ground cover and lianas,which belongd to 27 families,most of which belong to Asparagaceae,Amaryllidaceae,Oxalidaceae and Iridaceae.The common understory shrubs in the green space of the park mainly included Pittosporaceae pittosporum,Ericaceae rhododendron,Hypericaceae hypericum,Rosaceae photinia,etc.For shade tolerant ground cover plants,Asphodelaceae hemerocallis,Asparagaceae hosta,Asteraceae farfugium,Iridaceae iris,and Amaryllidaceae lycoris were mainly used.More efforts should be made to explore and introduce shade tolerant plants,expand their understory application,and attach importance to increasing understory plant diversity,plant landscape configuration and hierarchy construction in the study area,so as to improve the urban understory landscape effect.
