| In order to accurately, objectively and comprehensively evaluate the water environmental quality of the Yangtze River and support the Yangtze River great protection, through the research and development of a series of management systems and technical specifications, based on the optimized and adjusted water environmental quality monitoring network, a network operation mechanism of combining automatic water quality monitoring and separate sampling and testing manual monitoring involving management system, monitoring technology, quality control and data review was established. Automatic and manual monitoring of total phosphorus pretreatment methods were studied, the matching and integration of automatic and manual monitoring data were realized. The integrated data was applied to the evaluation, early warning, assessment and ranking of the water environmental quality of the Yangtze River, and the operational running of the water environmental quality monitoring network of the Yangtze River was realized. |
