    Abstract: 本研究係從水工模型出發,比較不同物種之水生植物在抗流反應方面的種間差異。在水芹菜的研究中,發現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,根、莖與芽的生物量也隨之下降。
    鑑於適性植物種類可能是多元化的組成,因此本研究另針對不同的水生植物:台灣原生種—柳葉水蓑衣為材料,探討其面對不同流速之抗流機制的種間變化。結果顯示流速增加時,其生長速度、乾鮮重、直徑降低,但是與水芹菜反應不同的是水蓑衣在面對較高流速的環境,其平均根長變長,株高也較
    The present study is carried out in a simulated channel for examining how different aquatic macrophytes respond to different channel flow velocities in terms of changes in their flow resistance mechanisms. Preliminary research of the planting material Oen
