摘要

本研究在中俄边界乌苏里江最大的支流进行。木陵河流域经过长期的疏浚工程，水体浑浊严重。2015年对该河流浮游植物功能群演替及环境因子进行了采样。共鉴定出83种，隶属于17个功能类群，其中F、M、MP、P和y 5个功能类群占优势地位。浮游植物功能类群的季节演替顺序为M/P-F/MP/P-MP/P。Spearman相关分析和典型对应分析(CCA)结果表明，浮游植物官能团主要受营养物浓度和光有效性的影响，包括全氮(TN)、铵态氮(NH4+ -N)、硝态氮(NO3−-N)、氮磷比(N:P)、水深(D)和透明度(SD)。

Phytoplankton functional groups response to environmental parameters in Muling River basin of northeast China

The present study was carried out in the biggest tributary of Ussuri River of boundary between China and Russia. The Muling River basin has undergone a long-term dredging works, and waterbody became seriously turbid. The succession of phytoplankton functional groups succession and environmental factors in the river were sampled in 2015. We totally identified 83 species, belonging to 17 functional groups which 5 were predominant, including group F, M, MP, P and Y. The seasonal succession of phytoplankton functional groups was M/P-F/MP/P-MP/P. Results of Spearman correlation analysis and canonical correspondence analysis (CCA) revealed that phytoplankton functional groups were mainly influenced by nutrient concentrations and light availability including total nitrogen (TN), ammonium nitrogen (NH4+–N), nitrate nitrogen (NO3−–N), N:P ratio (N:P), water depth (D) and transparency (SD) in the basin.

期刊介绍： Annales de Limnologie - International Journal of Limnology publishes papers on the ecology of freshwater systems, ranging from studies of aquatic organisms, physical and chemical works which relate to the biological environment, to ecological applications and frameworks for water management directives. Main topics: Ecology of freshwater systems ; biodiversity, taxonomy, distribution patterns in space and time, biology of animals and plants ; experimental and conceptual studies which integrate laboratory and/or field work on physiology, population dynamics, biogeochemistry and nutrient dynamics, management, mathematical modelling ; techniques for sampling and chemical analyses, ecological applications, procedures which provide frameworks for environmental legislation.
