以浮游藻类的种群组成评价珠江广州段水质情况

The Appraisal of the Water Quality in the Zhujiang Guangzhou with the Composition of Planktonic Algae

2002年3月对珠江广州段(广氮码头、车陂砂石场、北帝沙河段)3个采样点的浮游藻类种群组成进行调查,经鉴定统计共有浮游藻类574种,总个体数为108298个,分别隶属于裸藻门、绿藻门、蓝藻门、硅藻门、金藻门.采用Lloyd—Ghelardi的均匀度指数对水质进行评价,研究结果表明,均匀度指数车陂砂石场(e=0.5)>北帝沙(e=0.4774)>广氮码头(e=0.3240).珠江广州段(广氮码头至北帝沙河段)水质基本上是属于β-中污带,含油废水污染比较突出.

In March 2003,we examined the composition of planktonic algae (from wharf of Guangdan to Beidishahe),three sampling places (Guangdan wharf,Chebosha shichang,Beidisha). 574 species of planktonic algae were found,and the total number is 108 298. They belong respectively to Rhodophyta,Cyanophyta,Bacillariophyta,Chrysophyta and Pyrrophyta. We made an appraisal of water quality with lyody-chelarrdi and Phaeophyta. The result is Beidisha e=0.4774,Guangdan Wharf e=0.324,Chebosha e=0.5.The water from wharf of Guangdan to Beidishahe is practically polluted,the pollution of water containing oil is quite an alarming fact.
