摘　　要：海草的分类划分同题相当混乱,作者在通过数值分类对海草的分类进行探讨基础上,利用支序分类,借助计算机技术,详细地探讨海草各科间的系统演化关系,对海草进行新的分类划分。The purpose of this article is to investigate the cladistic method for systematic taxonomy of seagrasses. Seagrasses occur world-wide with over 50 nominal species described. Ten characters have been selected for a cladistic analysis of twelve genera. Arcozostera is treated as the outgroup. We present an analysis which suggests a revised classification of seagrasses involving subdivision of the group into five families. They are Zosteraceae, Thalassiaceae, Amphibolisaceae, Posidoniaceae and Enhalusaceae.
