Abstract

An environmental impact assessment method based on an atmospheric diffusion model and a linear programming is characterized in that the method comprises the following steps: (1) determining an assessment area on an atmospheric diffusion model platform and dividing the assessment area into computational grids; (2) establishing a parameter database of the assessment area which meets the requirementsof the atmospheric diffusion model platform, and selecting several points of interest in the assessment area; (3) The atmospheric diffusion model platform outputs the results of the concentration contribution value of each pollutant emitted from each pollution source to each point of interest for use by the linear programming platform; (4) the linear programming platform establishes the maximum emission model of atmospheric pollutants, the model is as follows: the objective function is f (Q) = D * B * Q 0 * A; (5) After waiting for the end of the current appraisal cycle, return to step (3) toenter the next appraisal cycle. The method of environmental impact assessment based on atmospheric diffusion model and linear programming has high accuracy and real-time performance.

Description

technical field

[0001] The invention relates to the technical field of environmental impact assessment, in particular to an environmental impact assessment method based on an atmospheric diffusion model and linear programming. Background technique

[0002] At present, the environmental impact assessment method generally adopts the linear programming method to plan and evaluate the emission of pollutants by establishing the maximum emission model of air pollutants, so as to achieve the control of the total amount of air pollutants in the region and improve the quality of the regional air environment. Linear programming can be automatically realized by using the Matlab platform, but the constraints and indicators used in linear programming are often static, simple, and artificially calculated, while the diffusion of atmospheric pollutants is a complex, dynamic, and nonlinear process , so it is difficult to obtain real-time and dynamic environmental impact assessment results, w...
