Air-ground-space integrated hyperspectral water quality monitoring and analyzing method

Abstract

The invention provides an air-ground-space integrated hyperspectral water quality monitoring and analyzing method. The method comprises the following steps of: S1, acquiring of water quality monitoring data: including hyperspectral data acquisition and water body sample data acquisition; S2, water quality monitoring data processing: performing data processing on the acquired multi-source water quality monitoring data; S3, establishment of a water quality parameter inversion model: establishing a water quality parameter inversion model according to the multi-source hyperspectral monitoring data, and modeling the water quality parameters through the inversion model based on artificial intelligence; and S4, water quality parameter inversion analysis. The beneficial effects of the air-ground-space integrated hyperspectral water quality monitoring and analyzing method are that: the method can meet the requirement of large-range water quality monitoring, can reflect the distribution and change conditions of the water quality in space and time, can make up defects that water surface sampling is singly adopted, can find pollution source distribution and migration characteristics and influence ranges of pollutants which are difficult to reveal by some conventional methods, can provide a basis for scientifically monitoring the water environment, and has the remarkable characteristics ofhigh dynamic, low cost and macroscopicity.

Description

technical field [0001] The invention relates to a water quality monitoring and analysis method, in particular to an air-ground integrated hyperspectral water quality monitoring and analysis method. Background technique [0002] The deteriorating water quality of my country's urban water bodies and the shortage of fresh water resources have attracted great attention from the state and society. Water pollution is becoming more and more common in urban rivers and has become one of the ubiquitous problems in the urban water environment, seriously affecting the image of the city, the ecological environment and the physical and mental health of citizens. The water quality of inland water bodies affects people's production and life, so accurate and efficient water quality monitoring is particularly important. Water quality monitoring is the main basis for water quality evaluation and water pollution prevention and control, so its significance is becoming more and more significant. ...

Problems solved by technology

[0003] The conventional water environment monitoring method is to collect water samples from the water body to be monitored, send them to the laboratory for water quality analysis, or build a water quality monitoring network. Although these methods can make accurate analysis and evaluation of many water quality parameters, they are time-consuming and laborious. It is not economical, and the number of water samples collected and analyzed is very limited. For the entire water body, the data of these measuring points only have local and typical representative significance, and are not enough to reflect the temporal and spatial changes of water pollution.
