摘　　要：对绿潮的主要组成种类之一扁浒苔进行了分子鉴定和生活史的初步研究。ITS序列分析结果显示,12个样品聚为3个类群,即Ulva-linza-procera-prolifera(LPP)复合体类群(7个样品)、Ulva compressa类群(4个样品)以及Ulva flexuosa类群(1个样品)。扁浒苔的生活史主要包括单性生殖、无性生殖和有性生殖3种方式,单性生殖最为常见,有性生殖相对较少。In this research,based on molecular identification,we studied the life history of Ulva compressa,one of main contributing species for the green tide. ITS sequence analysis showed that 12 samples were clustered into 3 different cladesUlva linza-procera-prolifera（LPP）（7 samples）,Ulva compressa（4 samples）and Ulva flexuosa（1 sample）. Three different reproduction modes of Ulva compressa were observed parthenogenesis, asexual and sexual reproduction, among which parthenogenesis was the most common mode and sexual reproduction was relatively less.
