摘    要:江蓠属大型海藻具有产氧强及高效吸收营养盐的特点,可用来缓冲赤潮消亡、崩溃造成的生态影响.本文的研究是在已发生骨条藻赤潮的系统中添加龙须菜,调节及缓冲赤潮系统的生态脆弱性.结果表明,水体中2kg/m^3密度的龙须菜可以较好地供应氧及稳定pH,并大量吸收营养盐及控制水体中的异养细菌的剧增,此外,该密度龙须菜的添加还能促进介质中单一微藻种群的改变,使得系统中的优势微藻种类的增加和丰度的下降.

关 键 词:海洋生态  骨条藻  赤潮  龙须菜  缓冲作用  中肋骨条藻  大型海藻  添加  高效吸收  生态脆弱性

Abstract:The die-out or crash of HAB is the most serious phase to enanger fishery. Macroalgae, Gracilaria , hold several characteristics, such as high ability to produce oxygen, rapid uptake to nutrients, can be used to buffer and modulate negative effects of HAB. This article investigated the function of G. lemaneiformis in system with Skeletonema costatum bloom, the result is as followed: G. lemaneiformis of 2 kg/m3 is enough to provide water bodies with dissolved oxygen ( DO) and stabilize pH value as well as uptake nutrients and bacterium control. Moreover, this density of macroalga can promote tha variation of phytoplankton population, increasing dominant species and decreesing, microalgal abundance.
Keywords:marine ecology  Skeletonema costatum  HAB  Gracilaria lemaneiformis  buffereffect
