简介：自从2007，Ulvaprolifera在黄海引起的巨大的绿潮每夏天发生了并且为本地政府引起了巨大的经济损失。Subei(诺思江苏省，中国)浅与它的大规模Porphyra水产业，被认为是U的最重要的来源。为绿潮的prolifera。揭示在西南的黄海在这个区域，水流的特征，温度，咸度和推迟的微粒物质(SPM)漂浮和漂流的水藻的物理机制，特别在Subei浅，被学习。光线的沙的地形学在Subei隆起浅抑制水流和原因网的特征纵、纬度的运动。纵的网运动是能带U的一个主导的动态因素。prolifera进近海流水。被水藻在光合作用期间生产的气体的数量决定是否U。在它从Porphyraaquacultural仪器被处理进水以后，prolifera能漂浮很好在海表面上。Subei浅被高混浊描绘，它能导致重要轻变细并且和U的快活影响光合作用。水里的prolifera。根据从2012的卫星遥感数据，在Subei的three-month-averaged表面SPM(4月，5月和6月)浅是140mg/dm3,和Subei的北方浅(34.5的北方
