摘　　要：于2014年1月至2015年12月对我国沿海城市的大型沙滩潮间带进行季节性的沙粒硅藻样品采集与处理,利用扫描电子显微镜(SEM)进行形态学观察与拍照,对常见沙生环境生活硅藻进行了形态分类学的初步研究,共记录到3种中国新记录海洋硅藻种类,分别是甜蹄状藻(Hippodonta dulcis(Patrick)Potapova)、密福氏藻(Fogedia densa Park,Khim,Koh&Witkowski)和科威特曲壳藻(Achnanthes kuwaitensis Hendey),对它们的分类特征以及生态分布特点进行了描述,并提供了每个种的扫描电镜照片.Sandy grain samples were collected in the intertidal zone of beaches from several cities along the coastline of China seasonally during January 2014 to December 2015.The morphological taxonomy of mezophytopsammic diatoms were preliminarily studied using scanning electron microscope （SEM）.Three species were identified as new records in China, which were Hippodonta dulcis （Patrick） Potapova,Fogedia densa Park,Khim,Koh＆Witkowski,Achnanthes kuwaitensis Hendey.The morphological characteristics,habits and their distribution were described together with SEM photos of each species.
