辽河口地区浮游植物群落时空分布特征

Spatial and temporal distribution of phytoplankton communities in Liaohe Estuary

浮游植物可作为鱼产潜力估算的重要依据,在水域生态系统的上行效应和下行效应中发挥重要的作用,浮游植物的时空分布对环境因子有着重要的指示作用。本文针对2015年平水期和丰水期的大辽河、双台子河、大凌河及绕阳河浮游植物进行了定性与定量采样分析,通过对浮游植物时空分布的研究,间接反应出了河口营养时空分布状态,有助于提升河口环境管理的科学决策水平,可为我国河口海域的生态监测和管理等提供参考。

Phytoplankton can be used as an important basis for estimation of fish production potential,and play an important role in the upswing and downswing effects of aquatic ecosystems.The spatial and temporal distribution of phytoplankton is an important indicator of environmental factors.This paper conducted qualitative and quantitative sampling analysis of phytoplankton in Daliao River,Shuangtaizi River,Daling River and Huanyang River during normal and wet seasons in 2015.Through the study on the spatial and temporal distribution of phytoplankton,the spatial and temporal distribution of estuarine nutrients is indirectly reflected,which is helpful to improve the scientific decision-making level of estuarine environmental management.It can provide reference for ecological monitoring and management of estuarine sea area in China.
