Abstract

The invention discloses a method for comprehensive environmental assessment and prediction based on remote sensing images, which collects satellite remote sensing images and environmental data of target areas through a data information system, and establishes a basic database; Parameters; based on the basic database and parameters, an environmental simulation prediction model is established; and the temporal and spatial distribution of pollutant concentrations is simulated through the environmental simulation prediction model; recently, the simulation results are analyzed with big data and imported into ArcGIS and web platforms to realize real-time dynamic visualization of simulation results show. The present invention can visually and intuitively display the pollutant concentration distribution and its dynamic changes at different times and in different spatial positions; provide a visual and intuitive performance platform for emergency treatment, and can effectively assist emergency decision-making.

Description

technical field [0001] The present invention relates to the field of environment prediction and assessment, in particular to a method for comprehensive assessment and prediction of environment based on remote sensing images. Background technique [0002] At present, the methods for comprehensive assessment and prediction of the environment (atmosphere, soil and groundwater) mainly include professional judgment method, analogy analysis method, mathematical model method and physical model method. [0003] Among them, for the professional judgment method, because it can qualitatively judge the environmental impact of the atmosphere, soil and groundwater. This method is generally used when the environmental impact problem is special and it is difficult to accurately identify its environmental impact characteristics or it is impossible to use common methods to predict the environmental impact. [0004] The analogy analysis method belongs to qualitative or semi-quantitative predi...
