Original river basin monitoring technology includes traditional manual monitoring, automatic station monitoring of quality of water and remote sensing monitoring. Due to the inefficiency of manual monitoring, it has become an auxiliary measure for river basin supervision in recent years. The continuous water quality data can be obtained in real time by the online automatic monitoring station of the river basin, but the coverage and the monitoring range of the online automatic monitoring station have limitations. Although the remote sensing technology can obtain high-precision and large-range monitoring data, the remote sensing technology is easily affected by weather, and hidden pollution areas are difficult to identify. So modern river basin monitoring systems are gradually developing towards the intelligent direction of air-day-ground integration. As pollution source emission is a decisive factor for causing the water quality of the receiving water body not to reach the standard, the field of pollution source monitoring and watershed water body monitoring does not form a unified linkage monitoring network for a long time. The two sets of monitoring systems independently operate, the technology is fused and relatively split, a large number of environment-friendly monitoring devices are in an individual combat state, and the phenomena of data fragmentation and data island are prominent. The dynamic and continuous three-dimensional monitoring system of the pollution source and the watershed water quality can not be effectively established, and becomes an important technical bottleneck for limiting the water environment treatment and management development.
