Method for comprehensively evaluating regional abrupt environmental pollution accident risk

Abstract

The invention discloses a method for comprehensively evaluating a regional abrupt environmental pollution accident risk. The method comprises the following steps: building a multilayer evaluation index system for the regional environmental pollution accident risk; building a risk source dangerousness quantitative model, a receptor sensitivity quantitative model and a restoring force quantitative model by using an objective weighting method, and acquiring risk source dangerousness indexes, receptor sensitivity indexes and restoring force indexes of different study units in a study region; building an environmental risk receptor vulnerability evaluation concept model and a regional abrupt environmental pollution accident comprehensive risk evaluation concept model, and calculating an environmental risk receptor vulnerability index and a regional environmental pollution accident comprehensive risk index according to the concept models, the risk source dangerousness indexes, the receptor sensitivity indexes and the restoring force indexes; and hierarchically clustering comprehensive environmental risk profiles of evaluation units. Through adoption of the method, a scientific theoretical foundation is laid for regional environmental risk comprehensive management, industrial distribution adjustment and optimization, accident emergency and the like. The method has the advantages of high efficiency, low cost, high accuracy and the like.

Description

technical field [0001] The invention relates to a plurality of subject fields such as geographical science, environmental science, disaster science, risk management and emergency management, and specifically relates to a comprehensive risk assessment method for regional sudden environmental pollution accidents. Background technique [0002] The risk of environmental pollution accidents refers to the probability and consequences of events that are caused by natural causes and human activities and can cause damage, damage or even destructive effects on human society and the natural environment through environmental media. Our country is in a critical period of accelerated transition to a modern society marked by industrialization and urbanization. In the process of this social change, the economy continues to grow at a high speed, and the level of industrialization and urbanization has been greatly improved. However, environmental risks are also deepening day by day, and sudde...
