【摘要】：采用现场调查、社会调查和卫星遥感多种手段相结合,调查了南黄海绿潮早期零星漂浮到大面积暴发的时空变化过程,分析了紫菜养殖工艺对绿潮暴发的影响,估算了南黄海不同紫菜养殖区输入海洋的绿潮藻初始生物量,并探讨了主要海域紫菜养殖面积的增长与绿潮暴发的关系。结果表明,受紫菜养殖生产工艺的影响,数以千吨的绿潮藻在短期内被刮落集中输入至海洋,为绿潮的暴发提供了最为直接和充足的绿潮藻初始生物量,其主要来源为竹根沙、蒋家沙和东沙紫菜养殖区。2005年以来,上述3个养殖区的紫菜养殖面积持续扩大,是2007年以来南黄海绿潮持续暴发的主要原因。水温是影响绿潮形成的关键环境因素,4~6月份大量被刮落入海的绿潮藻在适宜环境条件下漂浮和快速生长,并最终形成绿潮。
[Abstract]:Field investigation, social investigation and satellite remote sensing were used to investigate the temporal and spatial variation process of the South Huang Hai green tide, which floated sporadically to a large area in the early stage, and the effect of porphyra chinensis culture technology on the green tide outbreak was analyzed. The initial biomass of green tide algae in different porphyra culture areas of South Huang Hai was estimated, and the relationship between the increase of culture area of porphyra chinensis and the outbreak of green tide was discussed. The results showed that thousands of tons of green algae were scraped and concentrated into the ocean in a short time, which provided the most direct and sufficient initial biomass of green algae for the outbreak of green tide, the main source of which was bamboo root sand. Jiangjiasha and Dongsha porphyra culture zones. Since 2005, the area of porphyra mariculture in these three zones has been continuously expanded, which is the main reason for the continuous outbreak of the green tide in South Huang Hai since 2007. Water temperature is a key environmental factor affecting the formation of green tide. In June, a large number of green algae which were scraped into the sea floated and grew rapidly under suitable environmental conditions, and finally formed green tide.
