Abstract:	摘要許多研究已經證實植物對流速之影響力，也確認以植物材料作為緩衝可避免河岸沖蝕，然而，卻少有研究探討流速對於植物特性造成的影響，本研究擬由建構之人工水道探討（1）水生植物水芹菜因應不同流速下的形態變化，以及（2）界定水生植物在不同流速條件下的抗流耐度極限。研究結果顯示，水芹菜在不同流速下會產生如下的變化：當流速增高時，水芹菜之生長速度趨緩，莖芽變短且柔軟，以便增加植株的彈性，此外，並伴隨根長變短與降低根部錨定能力的現象。研究並發現，水芹菜的總新葉數與黃葉數的生長速度與不同的流速間呈現非線性相關，在流動的 Abstract Many studies have demonstrated that plants have the ability to affect flow velocity, and plant materials have been investigated for their potential to be used as a buffer zone to prevent riverbank erosion. However, relatively few studies have inv
