Regional comprehensive environmental risk assessment and division method

Abstract

The invention provides a regional comprehensive environmental risk assessment and division method. The environmental risk assessment and division can be regionally carried out to a large extent. The regional comprehensive environmental risk assessment and division method is characterized in that the essential factors of the environmental risks can be analyzed according to the regional comprehensive environmental risk system theory; a regional environmental risk assessment index system can be built, and the essential factors comprise risk sources, risk control mechanisms, risk fields, and risk receptors; the weight values and the assessment values of various indexes in the assessment index system can be determined based on the built assessment index system; the comprehensive environmental risk value of the assessment region can be acquired according to the weight values and the assessment values of various indexes of the assessment index system; the risk division of the assessment region can be carried out according to the preset classification method according to the comprehensive environmental risk value of the assessment region. The regional comprehensive environmental risk assessment and division method is suitable for the environmental science and technology field.

Description

technical field [0001] The present invention relates to the field of environmental science and technology, specifically to environmental risk management, in particular to a regional comprehensive environmental risk assessment and zoning method. Background technique [0002] Comprehensive environmental risk assessment is an emerging field in the current environmental protection work, which refers to the possible losses caused by various social and economic activities of human beings (including: natural disasters) to human health, social economy, ecological system, etc. On the one hand, it is the urgent need for environmental protection, and on the other hand, it is the inevitable result of the development of environmental science. [0003] my country's comprehensive environmental risk assessment research started in the 1990s, mainly to introduce and apply foreign research results, without its own assessment procedures, methods and techniques. After the 1990s, the content of ...

Problems solved by technology

[0009] The technical problem to be solved by the present invention is to provide a regional comprehensive environmental risk assessment and zoning method to solve the problem that the existing technology for a single risk factor comprehensive environmental risk assessment and zoning method for small-scale areas can no longer meet the needs of mesoscale areas and above. The need for environmental risk supervision, and the existing comprehensive environmental risk assessment and zoning methods ignore the effectiveness of control mechanisms, risk field characteristics, and the role of receptor vulnerability in the environmental risk assessment system, resulting in the inability to fully reflect the assessment area. The question of the real local environmental risk level
