摘　　要：我国黄海绿潮是目前世界上发生规模最大的绿潮灾害。浒苔(Ulva prolifera)由于其独特的生物学特性,在与其他海藻竞争中占据明显优势,导致暴发性生长从而形成浒苔绿潮。目前迫切需要验证并完善有效可行的漂浮浒苔藻体健康评价体系,来判断其生长状态、健康状况及增殖潜力。文章研究了黄海青岛海域漂浮绿潮藻浒苔光合作用的基本特性,并评价了其健康状况的等级。根据藻体状态对应其颜色和最大光量子产量(Fv/Fm)的差异,对2016年6—7月青岛近岸海域的漂浮浒苔藻体健康状态等级进行了测定和评价,发现各采样站位的浒苔藻体处于以下3个不同等级:Ⅱ级亚健康藻体,其Fv/Fm最高出现在站位L24,仅为0.66;Ⅲ级半健康藻体,其Fv/Fm最高出现在L2,为0.59;Ⅳ级衰老藻体,其Fv/Fm最高出现在L1,仅为0.40。其中,6月各采样站位主要以Ⅲ级和Ⅳ级藻体为主;而7月各站位主要以Ⅳ级藻体为主。结果表明,漂浮至青岛海域的绿潮藻浒苔大多状态较差,趋于衰亡,不能健康存活。研究处于不同时期漂浮浒苔藻体的光合生理参数,筛选合适的评价指标,并试用于绿潮监测和评价业务化工作中,对于今后确立黄海漂浮浒苔藻体健康评价方法以及预测绿潮发展趋势具有重要意义。The macroalgal blooms occurred in the Yellow Sea is currently the largest green tide disasters in the world. Because of its unique biological characteristics,Ulva prolifera occupy obvious advantage in the competition with other algae,leading to explosive growth in green tide.There s an urgent need to validate and perfect the effective and feasible health evaluation method for the green tide algae, to determine its growth status, health status and proliferation potential. This paper studied the photosynthetic physiological parameters and grade evaluation of free floating al gae Ulva prolifera along Qingdao coast area in the Yellow Sea.According to the algae physiolog cal states corresponding to the color and maximum light quantum yield （Fv/Fm）, in June and July,2016,the health status and the evaluation grade of free floating algae Ulwa prolifera along Qingdao coast in the Yellow Sea were determined. It was found that all samples belonged to the following three different levels： Grade Ⅱ ,sub health algae, its highest Fv/Fm value in 1.24 was only 0. 66 ;Grade Ⅲ ,ill health algae,its highest Fv/Fm in 1.2 was 0. 59 ;Grade IV,decayed algae, its highest Fv/Fm in IA was only 0.40.Furthermore,the health grades of floating Ulwa prolifera were mainly composed of Grade Ⅲ and Ⅳ in June and were predominated by Grade Ⅲin July,in dicating that most free floating Ulva prolifera could not survive in Qingdao coast. The results showed that most of the green tide algae was tending to decline, couldn＇t healthy survival. Research on photosynthetic physiological parameters, such as screening suitable evaluation index of the free floating green tide algae in different period is of great significance,which can be applied to the system of monitoring Ulva prolifera ,establishing the health evaluation method and fore casting the trend of green tide
