Environmental risk assessment method and device based on population distribution, and computer equipment

Abstract

The invention discloses an environmental risk assessment method and device based on population distribution, and computer equipment, relates to the field of information processing, and can solve the technical problem that current environmental risk assessment is inaccurate and unreasonable. The method comprises the following steps: acquiring regional sample data in a preset region, and training a population distribution prediction model by using the regional sample data; extracting first feature data in the target area, inputting the first feature data into the trained population distribution prediction model, obtaining a prediction result corresponding to second feature data, the first feature data at least comprise night light data, a normalized vegetation index, data elevation model data, a slope, an interest point and insurance data, and the prediction result corresponds to the second feature data, the second feature data comprise population distribution data; and determining pollutant concentration data in the target area, and performing data overlay analysis on the population distribution data and the pollutant concentration data to obtain an environmental risk assessment result.

Description

technical field [0001] The present application relates to the field of information processing, in particular to a population distribution-based environmental risk assessment method, device and computer equipment. Background technique [0002] Population growth and huge population have caused excessive consumption of land resources, energy resources, mineral resources, etc., and also caused serious environmental pollution and ecological damage. As the smog continues to break out across the country, the public is concerned about the 2.5 The awareness of the hazards of air pollutants in China has rapidly increased, and the demand for haze control across the country has reached unprecedented heights. [0003] At present, the pollution exposure risk of the population is generally evaluated by the pollutant concentration indicators of air quality monitoring stations. However, since the spatial distribution of pollutants is not consistent with the spatial distribution of the popu...
