The Response of River Biological Monitoring and Water Quality Based on Remote Sensing Image Technology

Abstract

With the development of space technology, the temporal resolution, spatial resolution and spectral resolution of remote sensing images have been greatly improved in accuracy. In the quantitative remote sensing monitoring of water quality, these characteristics of remote sensing images will affect the monitoring The accuracy of the results will have a great impact. Therefore, in the process of quantitative remote sensing monitoring of water quality, the selection of remote sensing image data is very important. In this paper, remote sensing image technology is used to study the biological monitoring and water quality responsiveness of a certain river. After taking water samples, SPOT-5 is used to obtain remote sensing data. After correlation analysis, the correlation of water quality indicators is obtained, and the response analysis of water quality indicators and microorganisms is carried out. The experimental results show that the total amount of microorganisms has a good response relationship with water quality.
