Intelligent monitoring, preventing and controlling method and intelligent monitoring, preventing and controlling system for ecological region

Abstract

The invention provides an intelligent monitoring, preventing and controlling method and an intelligent monitoring, preventing and controlling system for an ecological region. The intelligent monitoring, preventing and controlling method comprises the following steps: automatically collecting a water sample retained in farmland soil, a water sample retained in an ecological ditch and water samples in an entrance and an exit of artificial wetland, and acquiring related water quality indicators of all the water samples; then automatically detecting part of water quality indicators in the ecological ditch and part of water quality indicators at the exit of the artificial wetland, determining a corresponding preventing and controlling technology according to the acquired related water quality indicators in all the water samples, the automatically-detected part of water quality indicator in the ecological ditch and the automatically-detected part of water quality indicator at the exit of the artificial wetland, and evaluating the effect of a preventing and controlling technology of the ecological region. The support is provided for nitrogen and phosphorus runoff loss in field scale; moreover, a monitoring system for runoff loss of farmland surface water is established by the monitoring, preventing and controlling method.

Description

technical field [0001] The invention relates to the technical field of intelligent monitoring and prevention and control of ecological areas, in particular to an intelligent monitoring and prevention and control method and system for ecological areas. Background technique [0002] The deterioration of water environment caused by runoff of farmland surface water has become a common environmental problem in the world. Farmland surface water runoff loss is widespread, intermittent, and random, and the pollution load varies greatly in time and space. The output of surface water runoff loss and its influencing factors on different catchment scales often show different characteristics. The current research on the mechanism and process of farmland surface water runoff loss mainly focuses on the experimental observation, data analysis and process simulation at the farmland scale or runoff plot scale, but there are few studies on the overall ecosystem. Therefore, the establishment o...

AI Technical Summary

Problems solved by technology

[0003] The difficulties in establishing this system are as follows. First, because the detection interval has become the watershed interval, the traditional farmland soil and rainwater monitoring instruments can no longer meet the needs; Downstream monitoring and recording doubles the workload and difficulty

Third, because the staff cannot wait for the rain to fall in the farmland, the traditional monitoring method is that when the rain notification is received, the staff rush to the monitoring site to carry instruments for measurement, which often leads to the loss of important data in the early stage of rainfall

[0004] Moreover, the main controlling factors of farmland surface water runoff loss vary with the environment (such as topography, farming mode, soil properties, fertilization methods, and climate characteristics), so its prevention and control techniques and means are also difficult to determine
