【摘要】：采用現(xiàn)場(chǎng)調(diào)查、社會(huì)調(diào)查和衛(wèi)星遙感多種手段相結(jié)合,調(diào)查了南黃海綠潮早期零星漂浮到大面積暴發(fā)的時(shí)空變化過(guò)程,分析了紫菜養(yǎng)殖工藝對(duì)綠潮暴發(fā)的影響,估算了南黃海不同紫菜養(yǎng)殖區(qū)輸入海洋的綠潮藻初始生物量,并探討了主要海域紫菜養(yǎng)殖面積的增長(zhǎng)與綠潮暴發(fā)的關(guān)系。結(jié)果表明,受紫菜養(yǎng)殖生產(chǎn)工藝的影響,數(shù)以千噸的綠潮藻在短期內(nèi)被刮落集中輸入至海洋,為綠潮的暴發(fā)提供了最為直接和充足的綠潮藻初始生物量,其主要來(lái)源為竹根沙、蔣家沙和東沙紫菜養(yǎng)殖區(qū)。2005年以來(lái),上述3個(gè)養(yǎng)殖區(qū)的紫菜養(yǎng)殖面積持續(xù)擴(kuò)大,是2007年以來(lái)南黃海綠潮持續(xù)暴發(fā)的主要原因。水溫是影響綠潮形成的關(guān)鍵環(huán)境因素,4~6月份大量被刮落入海的綠潮藻在適宜環(huán)境條件下漂浮和快速生長(zhǎng),并最終形成綠潮。
[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.
