Research on Water Quality Monitoring and Evaluation System under Agricultural Irrigation Automation

Abstract

In order to timely grasp the status and change trend of the irrigated agricultural water environment, we refer to the farmland irrigation water quality evaluation standards, and select 11 monitoring items in different basins to monitor the agricultural irrigation water quality for 2 consecutive years. The article uses the pollution index method to evaluate the monitoring results. The results show that the comprehensive pollution index of surface irrigation water and underground irrigation water quality is less than 1, but there is a rising trend; the concentration of some pollutants in the irrigation return water is higher than that of the irrigation water, and some individual indicators exceed the standard, but they do not constitute comprehensive pollution. Finally, through the design of the remote sensing image water quality monitoring and evaluation system (RWQMES), the unified management of the three functions of water quality remote sensing image analysis and processing, water quality prediction and evaluation is realized.
