Enterprise cumulative environmental risk assessment system and method based on environmental risk system

Abstract

The invention discloses an enterprise cumulative environmental risk assessment system and method based on an environmental risk system, and belongs to the field of environmental science and environmental risks. The evaluation system and method are used for enterprise cumulative environmental risk evaluation. The method comprises the steps: based on an environmental risk system theory, establishingan enterprise cumulative environmental risk index evaluation model according to an enterprise cumulative environmental risk source index, an enterprise cumulative environmental risk management and control level index and an enterprise cumulative environmental risk receptor sensitivity index; and then grading the enterprise cumulative environmental risk, and evaluating the grade to which the enterprise cumulative environmental risk belongs according to the established index evaluation model. The method is not limited to a single pollutant, takes the enterprise as an evaluation object, effectively identifies the polluted enterprise with potential risks, has relatively high applicability and universality, can scientifically, systematically and accurately evaluate the cumulative environmentalrisks of the enterprise, and enriches the cumulative environmental risk evaluation theory.

Description

technical field [0001] The invention belongs to the field of environmental science and environmental risk, and in particular relates to an enterprise cumulative environmental risk assessment system and method based on an environmental risk system. Background technique [0002] Environmental risks can usually be divided into accidental environmental risks and cumulative environmental risks, among which cumulative environmental risks have been ignored for a long time due to their cumulative and concealed nature. In recent years, with the continuous deepening of our country's awareness of environmental risks, the scope, type and level of risk prevention and control have gradually improved, and cumulative environmental risks have received increasing attention and attention in environmental risk management and control. In the face of diversified cumulative environmental risks, it is an inevitable trend for effective risk management to identify cumulative environmental risk factor...

Problems solved by technology

[0004] At present, scholars at home and abroad have carried out many beneficial studies on cumulative environmental risk assessment, and have conducted a lot of discussions on cumulative environmental risk assessment frameworks, models and methods. However, most of the current cumulative risk assessment methods at home and abroad focus on environmental media ( (such as water, air, soil, etc.), focusing on a single pollutant or chemical as the research object, lack of cumulative environmental risk assessment for enterprises, and seldom focus on the possible impact on surrounding areas It is difficult to identify potential cumulative environmental risk enterprises from the source, and the applicability is weak in the actual business scenario of cumulative environmental risk management, so the versatility is relatively poor

In addition, the existing environmental risk assessment methods are relatively inaccurate in assessing cumulative environmental risks, and it is easy to divide the environmental risk levels of enterprises unreasonably, making it difficult to scientifically and accurately assess cumulative environmental risks
