摘要
为了更好地服务和支撑河长制的执行,及时准确掌握河流健康程度,对徽成盆地南河的水质优劣程度、饮用水水源地水质、水功能区水质进行外业监测及调查;对上述3个重要指标展开评估,经过加权计算得到南河化学完整性赋分。结果表明:南河水质优劣程度得分为94.6分,上游水质优于下游水质,中下游属于人类活动密集区,水质受到一定程度的影响;饮用水水源地各项检测项目均为合格,水质达标率为100%,赋分为100分;水功能区达标率100%,指标赋分100分;化学完整性得分为95.7分,处于非常健康状态。研究结果可为流域水生态修复、水资源规划、水生态保护提供技术支撑,也可为相似流域化学完整性评估提供参考。
To better serve and support the river chief system and grasp the health level of rivers timely and accurately,the field monitoring and investigation on the water quality of the Nanhe River Basin in the Huicheng Basin was conducted,including the status of water quality of Nanhe River,water quality of drinking water sources and functional areas.The above three indicators were evaluated and weighted to obtain the chemical integrity score of Nanhe River Basin.The results showed that the water quality of Nanhe River Basin scored at 94.6,with water quality at upstream better than the downstream.The middle and lower areas were densely populated with human activities,so the water quality was affected to a certain extent.All testing items in the drinking water source area were qualified,and the water quality compliance rate is 100%,with a score of 100 assigned.The compliance rate of the water function zone was 100%,and the indicator scored at 100.The chemical integrity score was 95.7,indicating a very healthy state.The study can provide technical support for watershed water ecological restoration,water resource planning and water ecological protection,which can also serves as a reference for chemical integrity assessment in similar watersheds.
