中文摘要 自生植物在提升雨水花园的植被稳定性、水文功能和生物多样性方面具有重要价值,但由于人们对其物种构成、生态适应性和观赏价值认知不足,其在雨水花园中的应用仍有限。文章以武汉江滩雨水花园为研究地,于春夏秋三季开展调查并分析自生植物群落组成及多样性特征的季节变化,通过AHP层次分析法从生境适应性、观赏价值和入侵风险3方面对自生植物的园林应用潜力进行定量评价。结果表明:1)雨水花园内共发现自生植物101种,隶属34科83属,其中菊科、禾本科和豆科为优势科,狗牙根在春夏季表现出显著优势,蝴蝶花在春夏秋三季均展现较高的优势度;2)春夏季的物种丰富度显著高于秋季,夏季的Shannon-Weiner多样性指数和Pielou均匀度指数显著低于春秋季,而Simpson优势度指数则显著高于春秋季,说明雨季雨洪冲刷对植物多样性具有环境过滤效应;3)根据园林应用潜力评价,蝴蝶花、狗牙根、紫云英、南苜蓿、野豌豆、美丽月见草和救荒野豌豆等物种表现出强适应性、一定观赏价值且入侵风险较低的特征。综上可知,武汉江滩雨水花园自生植物多样性具有显著季节变化特征;蝴蝶花、狗牙根、紫云英等物种是适合应用于华中地区雨水花园景观营造的自生植物种类。

英文摘要 Abstract:Spontaneous plants hold considerable value in enhancing vegetation stability, hydrological functions, and biodiversity in rain gardens. However, limited understanding of their species composition, ecological adaptability, and ornamental value has restricted their broader application. This study investigates the seasonal variations in community composition and species diversity of spontaneous plants in the rain gardens along the Yangtze River in Wuhan. Using the Analytic Hierarchy Process (AHP), we quantitatively evaluate the potential of each species in landscape application in terms of habitat adaptability, ornamental value, and invasion risk. Key findings include: 1) A total of 101 spontaneous plant species in 83 genera of 34 families are identified, dominant with Asteraceae, Poaceae, and Fabaceae. Cynodon dactylon displays significantly higher dominance in spring and summer communities, while Iris japonica maintains high dominance throughout all three seasons; 2) Species richness is notably higher in spring and summer than in autumn. In summer, the Shannon-Weiner diversity index and Pielou evenness index are significantly lower, while the Simpson dominance index is higher, indicating the environmental filtering effect of rainwater runoff; and 3) The evaluation of landscape application potentials reveals that the species like I. japonica, C. dactylon, Astragalus sinicus, Medicago polymorpha, Vicia sepium, Oenothera speciosa, and V. sativa have the traits of high adaptability, good ornamental value and low invasion risk. To sum up, there are significant seasonal variations in the diversity of spontaneous plants in the rain gardens along the Yangtze River in Wuhan, and the species such as I. japonica, C. dactylon, and A. sinicus are suitable to be applied to rain garden plantscape across the Central China.
