柳江市区段底栖动物的生态研究

Ecosystem Survey of Zoobenthos in the Cantonal of Liujiang

采用底栖动物作为指示物种对柳江的水生态进行了调查研究。结合相似水体研究结果比较,并辅以生物指数分析,对调查水域进行了水生态环境质量评价。结果表明,目前该水体明显受到污染,水质可初步划定为富营养型。提出了对该水域环境管理和改善水质的措施和建议。

The aquatic ecology of the Liujiang River Basin was investigated and evaluated by using benthic invertebrate as indicator species.Based on the present study and comparing with analogical water bodies,the environmental quality evaluation on the wetland area was carried out.The results suggested that the water quality of this area could be delimited to eutrophic type.Several countermeasures for protecting water environment and improving water quality were put forward.
