摘　　要：水质的人工监测与固定自动站监测断面数量有限、断面间距大,而水质自动巡测能够实现“高密度、多因子”的自由巡测,是研究水体污染物传输和分布规律一种新的技术方式,但目前该技术有待进一步在实践中运用与验证。利用“中国环监008”监测船,搭载自动监测设备,在长江干流(重庆至武汉区段)和三峡库区主要支流开展了水质巡测,掌握了长江重庆至武汉段水质状况和沿江污染物空间分布特征,证明了部分污染物分布特征与区域生产生活产生的污染负荷之间的相关性。通过质量控制及比对监测,评估了水质巡测技术的可行性和有效性。研究成果为开展长江大尺度、快速、动态、连续自动监测,摸清区域性水质问题,排查长江水环境风险提供技术支撑。The numbers of manual monitoring section and fixed automatic monitoring station are limited and the spacing of monitoring section is large.Shipborne automatic monitoring of water quality is a new technical approach to study the transmission and distribution law of water pollutants as it can accomplish automatic monitoring with high density and multiple parameters.However,this technology needs to be further verified in applications.In this study,the"China Environmental Monitoring 008"monitoring ship was equipped with the automatic monitoring devicesto monitor the water quality in the mainstream of the Yangtze River(from Chongqing to Wuhan)and the Three Gorges Reservoir area.The spatial distribution characteristics of pollutants along the Yangtze River from Chongqing to Wuhan was obtained.Correlation was found between the distribution of some pollutants and pollution load produced by regional production and life.The feasibility and effectiveness of the automatic monitoring technology was evaluated through quality control and comparison between automatic monitoring and manual monitoring.The research finding provides technical support for large-scale,rapid,dynamic and continuous automatic monitoring of the Yangtze River and investigations on water quality characteristics and environmental risks.
