多年生草本植物在沈阳地区的适应性及应用研究

Adaptability and Landscape Application of Perennial Herbaceous Plants in Shenyang Area

在中国城市景观可持续和生物多样性的目标需求下,多年生草本植物已然受到风景园林领域的广泛关注。立足于沈阳地区,在沈阳及周边地区进行大量野外调查的基础上,运用单播方式对收集的45种多年生草本植物进行适应性试验,记录分析其生态适应性、物候期和生物特性等相关指标参数。筛选出37种在沈阳地区适应性较高的多年生草本植物,如白头翁(Pulsatillachinensis)、溪荪鸢尾(Iris sanguinea)、玉蝉花(I.ensata)、黄花败酱(Patrinia scabiosifolia)、芒(Miscanthussinensis)、埃丽蓝羊茅(Festucaglauca‘ElijahBlue’)、荆芥(Nepeta cataria)、狼尾草(Pennisetum alopecuroides)等,从空间结构和时间动态2个维度阐述景观应用策略。旨在挖掘更多具有生态价值和景观价值的多年生草本植物,拓展沈阳地区适生草本植物名录,为建立可持续的近自然草本植物群落提供基础数据和理论参考。

Perennial herbaceous plants have attracted the attention of landscape architecture and been widely used in landscape architecture at home and abroad under the multi-objective requirements of urban biodiversity and landscape sustainability in China. Based on a large number of field investigations in Shenyang and its surrounding areas, the adaptability test of 45 perennial herbaceous plants is carried out by means of broadcast sowing,and the related indexes of ecological adaptability, phenology and biological characteristics are recorded and analyzed 37 species of perennial herbs with high adaptability are selected in Shenyang area, such as Pulsatilla chinensis, Iris sanguinea, I. ensata, Patrinia scabiosifolia, Miscanthus sinensis, Festuca glauca ‘Elijah Blue’,and Pennisetum alopecuroides. The landscape application strategies of the 37 herbaceous plants are discussed from two dimensions of spatial structure and temporal dynamics. The purpose of the research is to excavate more perennial herbaceous plants with ecological and landscape values, expand the list of suitable plants established by herbaceous plant community in Shenyang area, and provide basic data and theoretical reference for the establishment of sustainable quasi-natural herbaceous plant community.
