Dangerous chemical road transportation ecological environment risk assessment method and system

Abstract

The invention discloses a dangerous chemical substance road transportation ecological environment risk assessment method, which comprises the following steps: (1) setting a risk assessment system based on a network, and (2) setting an environment risk assessment management module; (3) setting an environmental risk assessment sub-module; and (4) setting an environmental risk level evaluation modulefor determining the environmental risk level of the road section with the ecological environmental risk by combining the level of the ecological environmental sensitive receptor. The risk assessmentsystem comprises a basic information management module, an environment risk assessment management module, an environment risk assessment sub-module and an environment risk level assessment module which are mutually connected and run based on the network, and the level of the ecological environment sensitive receptor is combined with the road section with the ecological environment risk. Accordingto the invention, an ecological environment sensitive receptor influence derivation method is adopted to realize prediction simulation of an emergency environment event, which is helpful for improvingthe environment emergency disposal level.

Description

technical field [0001] The present invention relates to the technical field of environmental risk monitoring and governance, in particular to a method and system for assessing ecological environmental risks of road transport of hazardous chemicals. Background technique [0002] With the development of my country's social economy and technological level, the application of hazardous chemicals (hereinafter referred to as "hazardous chemicals") is becoming more and more extensive, and its production and transportation are also becoming more and more frequent. [0003] The transportation of dangerous goods in our country has always been a very special transportation industry. In my country, land road transport has become the main mode of transport for dangerous goods because it is less restricted by infrastructure than pipelines, railways, and waterways. [0004] Ecological environmental receptors refer to ecological entities exposed to the stress of environmental pollutants. ...

AI Technical Summary

Problems solved by technology

In particular, this technical solution does not take into account the degree of impact on ecological security of environmentally sensitive receptors (such as water bodies and the atmosphere) in the geographical area where each road section is located during the road transportation of hazardous chemicals from the perspective of watershed environmental protection and governance. , as well as the degree of environmental hazards, control and governance costs, etc.

[0007] Therefore, the existing technology cannot scientifically assess the risk of accidents such as road leakage during the transportation of hazardous chemicals from the perspective of environmental protection and emergency management. zoo and botanical gardens, etc.), and use this as a basic basis to screen and grade environmental risk road sections, and provide corresponding information for local governments, road administration departments, environmental protection management departments, traffic management departments, and managers of hazardous chemicals transportation and production enterprises. Scientific evaluation methods and decision-making basis to achieve the purpose of protecting regional environmental safety, reducing the accident rate and the degree of environmental damage during accidents
