    Abstract: 本研究係從模擬水道出發,探究不同群聚模式的水生植物對於不同流速之水道,在抗流力方面會產生如何之變化。研究結果發現,簇群栽培之水生植物,確實較單植者有較強之抗流能力,對環境之適應能力亦較單植者為強,以水芹菜為例,單植者在面對較高流速沖刷時,其生長速度趨緩,莖芽組織變得矮小且柔軟,以增加植物的抗流彈性,此外,其平均根長變短,錨定能力降低,乾鮮重與流速呈反比關係;至於簇群的水芹菜,在株高、根長與平均綠芽數方面,實驗組與控制組之差異並不明顯,但是平均單位面積之維管束數量仍是高流速之實驗組高於低流速之控制組,呈現與
    The aim of this study was to examine how clustered aquatic macrophytes respond to different channel flow velocities in terms of changes in their flow resistance mechanisms. Study results showed that the flow resistance ability and environmental adaptabili
