Problems solved by technology

[0006] Aiming at the problems existing in the prior art about natural disaster-induced technical accident disaster risk assessment methods being immature, risk spatial distribution pattern not clear, risk assessment accuracy not high, etc., the present invention provides a natural disaster-induced technical accident disaster risk assessment method and system , based on the four first-level indicators of risk sources, natural disaster hazards, control mechanism level, and receptor vulnerability, expand to the corresponding second-level indicators, build a risk assessment system, and comprehensively evaluate natural disaster-induced technical accident disasters in a region or watershed Risk index, and then identify the spatial pattern of natural disaster-induced technical accident disaster risk

Embodiment 1

[0037] The environmental risk system is an organic whole composed of environmental risk sources, environmental risk receptors and control mechanisms. The environmental risk sources harm the environmental risk receptors, and at the same time affect the control mechanism, representing the exposure and harmfulness of the environmental risk system; the control mechanism Protecting environmental risk receptors while controlling the hazards of anti-anti-environmental risk sources characterizes the effectiveness of the environmental risk system; environmental risk receptors withstand the hazards of environmental risk sources while affecting the control mechanism to characterize the vulnerability of environmental risk receptors. The risk assessment in this embodiment is based on the first-level indicators and the second-level indicators corresponding to the expansion of the first-level indicators to build a risk assessment system. The first-level indicators include risk source indicator...

Embodiment 2

[0091] This embodiment is basically the same as Embodiment 1, the difference is that the disaster-causing factors of natural disasters in this embodiment are specifically described by taking geological disaster factors as an example. In this example, natural disasters induced by geological disaster factors induce technical accident disaster risk When calculating the index CRG, the first-level indicators obtained by the data acquisition module include risk source indicators (SG), geological hazard hazard indicators (HG), control mechanism level indicators (CG) and receptor vulnerability indicators (VG). Among them, the calculation methods of the risk source index SG, the control mechanism level index CG and the receptor vulnerability index VG are the same as those in Example 1 when the natural disaster disaster-causing factor is the flood disaster-causing factor.

[0092] Geological hazard factor data include magnitude index, focal depth index, seismic intensity index caused by ...

Embodiment 3

[0109] This embodiment is basically the same as Embodiment 1 and Embodiment 2, the difference is that the disaster-causing factors of natural disasters in this embodiment are specifically described by taking typhoon-induced as an example. In this example, the natural disasters induced by typhoon induce technical accident disaster When calculating the risk index CRT, the first-level indicators acquired by the data acquisition module include risk source indicators (ST), typhoon hazard factor indicators (HT), control mechanism level indicators (CT) and vulnerability indicators (VT). Among them, the calculation methods of the risk source index ST, the control mechanism level index CT and the receptor vulnerability index VT are the same as those in Example 1 when the natural disaster disaster-causing factor is the flood disaster-causing factor.

[0110]Typhoon hazard factor data include typhoon duration index, typhoon frequency index, typhoon affected area precipitation index, direc...

Abstract

The invention discloses a natural disaster induction technology accident disaster risk assessment method and system, and belongs to the technical field of risk assessment. In order to solve the problems of immature accident disaster risk assessment method, unclear risk spatial distribution pattern, low risk assessment accuracy and the like of a natural disaster induction technology in the prior art, the invention provides a risk assessment method and system. The method comprises the following steps of enlarging four types of first-grade indexes including a risk source, a natural disaster causing factor, a control mechanism level and receptor vulnerability to corresponding secondary indexes, finishing indexes calculations according to scores acquired by calculations of an analytic hierarchyprocess, constructing a risk assessment system, and calculating risk indexes. The assessment method is high in universality, a basis can be provided for further evaluation and risk management of theNatch risk, priority determination and key point evaluation are carried out on a Natch high-risk-level area, and the evaluation method can also be used as a basis for evaluating and analyzing the Natch risk in the area, the drainage basin or within the nation.

Description

technical field [0001] The present invention relates to the technical field of risk assessment, more specifically, to a method and system for assessing the risk of technical accidents induced by natural disasters. Background technique [0002] With the continuous development of industry and the continuous occurrence of environmental risk accidents, people's management of environmental risks is becoming increasingly stringent, especially in the current environment of frequent natural disasters, which pose constant threats to key industrial development areas and industrial-intensive areas promote. Therefore, the environmental and safety incidents of industrial enterprises caused by natural disasters will become one of the focuses of the authorities. This kind of technical accidents caused by natural disasters is called natural disaster-induced technical accident disaster (Natech) risk. A Natech is a low-probability but high-impact risk event that could involve the release of ...
