摘要
采用常规测试方法对村镇级河道——崇明瀛东村中心河的污染现状、影响因子进行了研究,并对其限制营养元素进行了分析。结果表明,瀛东村中心河水体处于富营养状态,磷为限制性营养元素,受人为干扰强烈,居民区和汇水区营养元素含量偏高;水体环境较适于藻类生长,具有藻类暴发的潜在威胁。
The pollution status and influencing factors of central channel which is a village channel in Yingdong Village of Chongming Island were studied by adopting the method of routine test,and its limited nutrient elements were also analyzed.The results showed that the water of the central channel was at the level of eutrophication,and phosphorus was the limited nutrient element.Due to the strong artificial interference,the contents of nutrient elements were large in residential areas and gathering ground.The water environment was adapted to the growth of algae,which had a potential threaten of algae bloom.
