广州荔湾湖整治前后生态环境变化调查

Investigation of Eco-environment Variety in Liwan Lake of Guangzhou After Field Curing

文章根据广州荔湾湖清淤截污前后水质监测结果、水生物藻类和鱼类鉴定及荔湾湖周边植被调查进行综合分析,结果表明:荔湾湖水质有了一定的好转,生物多样性也有明显改善,但湖水水质仍处于富营养状态,部分污染物浓度仍较高。因而,荔湾湖的环保工作应进一步加强,使该湖区水质达到广州市水质标准。

The results of water quality monitoring and algae-fish-vegetation investigation showed that,after field curing the waterquality of Liwan Lake was improved,and biological diversity increased obviously. However,the lake is still eutrophicated and the concen-trations of some pollutants are still high. Therefore,the environmental protection work around Liwan Lake should be further strengthened tomake water quality of the Lake meet the water quality standard of Guangzhou City.
