Abstract
浮游植物作为海洋生态系统中最主要的初级生产者,是整个海洋食物链的起点和生物地化循环的重要环节。浮游植物群落结构与动态直接影响并反映着生态系统的稳定性,其群落的组成变化对海洋环境和全球气候有着深刻的影响。本文根据2011年4月(春季)和8月(夏季)分别在北部湾北部海域(20.06°N~21.46°N,108.25°E~109.88°E)进行了两个航次的调查,对调查区域浮游植物群落生态特征进行了初步研究。研究内容包括浮游植物群落的种类组成、数量分布、生物多样性、群落划分、空间生态位以及叶绿素a和初级生产力的水平分布,并且探讨了环境因子对其季节变动的调控机制。主要结果如下: (1)浮游植物的种类组...
 
As the main component of primary producers in marine ecosystems, phytoplankton is the starting point of the entire marine food chain and a vital link in the biogeochemical cycle. Phytoplankton community structure and dynamics directly reflect the stability of the ecosystem, which has a profound impact on the marine environment and global climate. Two cruises were carried out in northern Beibu Gu...
