广西北部湾海域球形棕囊藻囊体时空分布及其影响因素
|
摘要
为揭示广西北部湾海域球形棕囊藻囊体的时空分布特征,探讨其与水体环境因素的关系,于2016年12月至2017年6月对该海域29个站位进行了6次综合调查。结果表明,调查海域球形棕囊藻囊体丰度介于0—4.09×10~4col/m~3,12月至次年3月囊体丰度较高;西南深水区域囊体丰度呈现逐月递减趋势,而广西和雷州半岛近岸海域囊体丰度呈现先升高再降低的趋势。相关性分析显示该海域囊体丰度与水温、磷酸盐和硅酸盐浓度呈显著负相关(P<0.01);与叶绿素a浓度、溶解氧呈显著正相关(P<0.01);在局部区域与盐度呈显著正相关(P<0.01),与硝酸盐浓度呈显著负相关(P<0.01)。典型站位分析结果显示球形棕囊藻囊体丰度的变化趋势与其他浮游植物的相同,而与群落多样性指数的变化趋势相反。球形棕囊藻囊体的时空分布主要取决于环境条件的变化,也会受到其他浮游植物群落结构改变的影响。
We investigated the spatial-temporal distribution of Phaeocystis globosa colonies in monthly cruise from December 2016 to June 2017 in Beibu Gulf, Guangxi, South China Sea, and analyzed the correlation between P. globosa colonies and environmental factors. Results show that P. globosa colony abundance was between 0 and 4.09×10~4 col/m~3,and the P. globosa colonies were abundant from December 2016 to March 2017. The colony abundance decreased month by month in the southwestern part of the investigation area, while fluctuated in the coastal waters of Guangxi and the western waters of Leizhou Peninsula. Correlation analysis colicated that colony abundance was correlated negatively with temperature, phosphate, and silicate(P<0.01), and positively with chlorophyll a and dissolved oxygen(P<0.01) in the study area. A significant positive correlation was found between colony abundance and salinity(P<0.01) in Region II of the study area and a significant negative correlation between coloney abundance and nitrate(P<0.01) in Region IV. The trend of colony abundance coincided with the abundance of other phytoplanktons, but was contrary to the trend of community diversity colex in some stations. Overall, the spatial-temporal distribution of P. globosa colonies varied with environment conditions and structures of other phytoplankton communities.
