六盘水市双桥水库供水工程区浮游植物调查报告

The Report of phytoplankton in Shuangqiao Reservoir Water Supply Works Watershed

浮游植物是水体中的初级生产者,长期被当作水质的指示性生物。对双桥水库建设淹没区阿勒河8个采样点的调查表明,该区域浮游植物4门9目14科20属34种。其中蓝藻门Cyanophyta有3目5科8属11种,占总种数的32.35%;硅藻门Bacillariophyta有3目4科7属16种,占总种数的47.06%;绿藻门Chlorophyta有2目4科4属5种,占总种数的14.71%;裸藻门Euglenophyta有1目1科1属2种,占总种数的5.88%。优势种群是硅藻类。依指示生物法,水体为寡污带水质。

Phytoplankton is one of the most important primary producers,and it is often used as sensitive indicator of water monitoring. Based on the data of 8 sampling points in Shuangqiao reservoir watershed of Aare River, there 34 species of phytoplankton belong to 20 genera, 14 families, 9 orders and 4 phyla. Among them, there are 11 species, 8 genera, 5 families, 3 orders belong to Cyanophyta,accounting for 32.35% of the total;there are 16 species, 7 genera, 4 families, 3 orders belong to Bacillariophyta,accounting for 47.06% of the total;there are 5 species, 4 genera, 4 families, 2 orders belong to Chlorophyta,accounting for 14.71% of the total;and there are 2 species, only 1 order belong to Euglenophyta,accounting for 5.88% of the total. The Diatomeae is the Dominant Species. By means of biological indicator, the water pollution condition belong to oligosaprobic zone.
