Application of fine spectral detection and quantitative analysis technology in water quality and environmental monitoring of the Yangtze River main stream
Water eco-environment monitoring is the premise and foundation of habitat protection.In view of the characteristics of the Yangtze River Basin's water system,which is diverse,complex,and ever-changing,higher requirements are put forward for monitoring methods.At present,the water quality monitoring methods for large surface water systems are still mainly based on manual sampling combined with laboratory chemical analysis or on-site hand-held instrumental analysis.There are problems such as method lag,single means,low frequency,and lack of non-point sources.Therefore,there is an urgent need for new system monitoring technology,which breaks through real-time,fast,non-point source quantitative and other practical needs,and provides a reliable data source for the comprehensive simulation of the Yangtze River water system.In this context,this paper proposes a fine spectral detection and quantitative analysis technology with completely independent intellectual property rights,and develops ground-based,space-based and other system technologies and equipment.With the support of the relevant projects,the demonstration application of systematic technology was carried out,and the space-ground stereoscopic monitoring was conducted in the key sections of the main stream of the Yangtze River,the Three Gorges Demonstration Area and the Poyang Lake Demonstration Area,and good results were achieved.The monitoring data are connected to the"Yangtze River Simulator"through the cloud platform,which provides fast real-time data support for its comprehensive operation,as well as a new method and application model for the comprehensive monitoring of large-scale water systems in the future.
