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...
