三环泡湿地浮游生物群落结构时空分布特征研究

Spatial and Temporal Distribution of Plankton Community in Sanhuanpao Wetlands

三环泡湿地位于黑龙江省三江平原腹地,是典型的内陆淡水沼泽、湖泊湿地,是三江平原湿地的典型代表。作为湿地水生生态系统的初级生产者和食物链基础环节的浮游植物和浮游动物,由于对环境变化敏感,其群落变化常被认为是评价水环境质量的一个重要指标。文章通过对三环泡湿地浮游生物的种类组成和水平分布的调查与分析,确定了三环泡湿地浮游生物的常见种和优势种,分析了三环泡湿地浮游生物群落结构时空分布的特征,对揭示东北不同类型湿地浮游生物功能群对各种人为污染的响应机制具有重要意义。

Sanhuanpao wetland is located in the hinterland of the Sanjiang Plain in Heilongjiang Province.It is a typical inland fresh water swamp and lake wetland,and is a typical representative of wetlands in the Sanjiang Plain.Phytoplankton and zooplankton,which are primary producers of wetland aquatic ecosystems and the food chain linkages,are often considered as important indicators of water quality due to their sensitivity to environmental changes.Through the investigation and analysis of the species composition and horizontal distribution of plankton in Sanhuanpao wetlands,the common species and dominant species of plankton in Sanhuanpao wetlands were determined.The characteristics of spatial and temporal distribution of the plankton communities in Sanhuanpao wetlands were analyzed.Phytoplankton functional groups in different types of wetlands in northeast China are of great significance to various man-made pollution response mechanisms.
