Pollution source management system based on geographic information system (GIS) technology and one-dimensional water quality model and operation method thereof

Abstract

The invention provides a pollution source management system based on a geographic information system (GIS) technology and a one-dimensional water quality model. The pollution source management system comprises a basic geographic database, a water quality monitoring database, a pollution source monitoring database, a water quality model predicting module, a statistical analysis module and a geographic information system module. The invention also provides an operation method of the pollution source management system based on the GIS technology and the one-dimensional water quality model; and by means of the operation method, the docking between a geographic information system and a management information system is realized to complete the effective management of a large amount of environmental information, analyze the changes in the environmental pollutants, and realize the visualization of a regional environmental pollution status, and thus, the execution of the water environment planning and decision is facilitated.

Description

technical field [0001] The invention belongs to the field of environmental information systems, and in particular relates to a pollution source management system based on GIS technology and a one-dimensional water quality model and an operation method thereof. Background technique [0002] In the 21st century, China's water environment is facing three serious problems: water shortage, water pollution, and floods. Among them, water pollution has led to a sharp decline in the quality of the water environment, so water pollution is an urgent problem to be solved. In natural rivers, when pollutants are discharged by non-point source discharge or in the uniform mixing section downstream of the pollution zone, the one-dimensional water quality model is a common method for quantitative calculation of water resource protection and water pollution control. The water quality model is a mathematical description of the water quality change law of a water body. It has advantages in nume...

AI Technical Summary

Problems solved by technology

The water quality model is a mathematical description of the changing law of water quality, which has advantages in numerical calculation and parameter setting, but is limited in data management, visualization of simulation results, and expressive capabilities of spatial analysis.

[0003] At present, the existing pollution source management systems have the following shortcomings: many systems realize the functions of editing, browsing, querying, statistical analysis and output of pollution data, but only stay at the management efficiency of pollution source data; many systems introduce geographical information System (GIS) technology mainly uses its spatial analysis and visualization effects, but its simulation function is lacking in the application system of water quality; many systems focus on the multi-level and multi-directional visual display of environmental data, but fail to realize the data analysis. Dynamic management and dynamic changes in the distribution of pollution sources; many systems use GIS technology and use its thematic map function to quickly display the environmental statistical report data on the map, which improves work efficiency and provides a clear effect in the visualization effect. Changes in the concentration of pollutants in rivers are not deeply reflected
