昭通省耕公园水体藻类群落组成与水质分析

Analysis of Algae Community Composition and Water Quality of Shenggeng Park in Zhaotong City

通过对昭通市昭阳区省耕公园水体藻类多次采集、观察、鉴定,研究藻类群落组成及水质分析,发挥淡水藻类对水环境的监测作用;鉴定结果:鉴定了藻类植物340种(包括变种),隶属9门,52科,101属,优势种为绿藻门(26科,55属,180种),亚优势种为硅藻门(9科,19属,99种),根据优势种与营养状态的对应关系、复合藻商法和绿藻商法三个指标,确定了省耕公园的水体质量为富营养型。

Through repeated collection,observation and identification of algae of Shenggeng Park in Zhaotong City,this paper studied algae community composition and water quality analysis,and played the monitoring role of freshwater algae on water environment.The results showed that:340 species(including varieties)of freshwater algae were recorded and identified,belonging to 9 phyla,52 families and 101 genera.The dominant species are Chlorophyta(26 families,55 genera,180 species),and the sub dominant species are Bacillariophyta(9 families,19 genera,99 species).According to the corresponding relationship of superior species and nutritional state,compound algae method and green algae method,the water quality of the provincial tillage park is eutrophic.
