泰山湖泊浮游动物群落优势种调查及分析

Surveys and Analysis of Dominant Species in Dahe Reservoir and Weiliao Lake of Taishan University.

本文通过对泰安地区的大河水库、泰山学院未了湖6个采样站点的浮游动物及其相关水环境指标进行了初步调查,共鉴定出16种浮游动物,其中轮虫6种,桡足类5种,枝角类2种,原生动物2种,糠虾1种.水域的主要优势种为轮虫和桡足类,而且所出现的优势种多为水体富营养化和渔场天然饵料的指示种.根据优势种指示生物法与理化因子相结合,推断该水域存在水体富营养化.

A preliminary investigation of zooplankton and related environmental indicators was get from six sampling stations, which located in Dahe Reservoir and Weiliao Lake of Taishan University. In this survey, 16 kinds of zooplankton were identified, including 6 kinds of rotifer, 5 kinds of copepoda, 2 kinds of cladocera, 1 kind of protozoa and 1 kind of mysidacea. The dominant species in the water are rotifer and copepoda, which are the indicator species of eutrophication and fishing natural bait. According to the combination of dominant species bioindicators and physical and chemical factors, we know that Dahe Reservoir and Weiliao Lake of Taishan University exist eutrophication.
