Research on non-point source pollution and prevention countermeasures of river basin based on remote sensing and GIS

Many environmental safety issues in real life have hidden periods. Take environmental pollution as an example. Excessive automobile exhaust gas may not have obvious adverse effects on the environment in a short period of time, but over time postpone, environmental problems will slowly surface. Therefore, traditional environmental problem monitoring procedures can often only detect environmental problems that may exist in a short time. The GIS environmental problem monitoring program introduced in this article has great advantages compared with the traditional monitoring program. The program uses advanced multimedia technology to perform statistical monitoring on the hydrological and environmental information of various regions, and can monitor the upcoming events in a certain area. It can effectively predict water pollution incidents. In addition, corresponding preventive measures are designed according to the degree of pollution in the accident, which provides great help for relevant departments to control environmental pollution and ensure environmental sanitation. At the same time, the program can also investigate the environmental problems that have occurred, analyze the technical means needed to solve the pollution problem, and provide technical support to relevant staff. © 2021, Saudi Society for Geosciences.
