Abstract

The invention discloses a method for monitoring hydrological area pollutant, and the method includes: 1, integrating a SWAT soil water evaluation model and a geographic information model, and evaluating and calculating NH4, TN, TP, COD and sediment content in the hydrology area by using area geographic information; 2: according to the content of pollutants, dividing the color of the sub-region into four levels: green, light green, yellow and red according to the classification rules of pollutants; 3: according to the content of pollutants, drawing out the change trend of pollution index of specified river and specified pollution points and sources; 4: according to the geographic information model, obtaining and adjusting of parameters of the pollution points and sources and new added pollution points and sources, and executing the step 1 until required pollution points and sources are completed; implementing data calculation, display, data output and early warning of hydrological area. The soil water evaluation model is combined with the geographic information model, which improves the calculation accuracy, solves the problem that general data model is not intuitive and is difficult to govern, so that the early warning is clear and intuitive.

Description

[0001] technical field [0002] The invention relates to the technical field of early warning and control of pollution in hydrological areas, in particular to a method for monitoring pollutants in hydrological areas. [0003] Background technique [0004] At present, more and more countries and regions in the world are applying remote sensing and telemetry technology, geographic information system, network communication technology, database technology and management information system to environmental monitoring, and have established an environmental online monitoring system based on comprehensive water quality indicators and specific projects. Monitoring information system. After years of vigorous development in many economic countries such as Europe and the United States, the online environmental monitoring information system has become more and more popular. A multi-level real-time monitoring system that can simultaneously reflect water quality concentration, total poll...
