Embodiment

[0135] Based on the community disaster prevention safety resilience assessment model, a fuzzy judgment matrix model is established. Through the pairwise comparison between different factors in the index layer, the importance of each index factor before each other can be determined. According to the degree of importance, the corresponding scale is obtained, the judgment matrix is ​​established, and the evaluation process is quantified.

[0136] The indicator weights are calculated as follows:

[0137] (1) The hierarchical structure analysis method calculates the weights

[0138] The following takes the No. 1 expert questionnaire as an example, and takes C in Table 1 "Community Disaster Prevention Safety Resilience Assessment System" 3 -C 6 The indicator layer is used as an example to introduce the calculation process. Expert No. 1's judgment on the importance of indicators in the "Community Disaster Prevention and Safety Resilience Assessment System" (for the assignment of ...

Abstract

The invention discloses a flood-disaster-oriented community disaster prevention toughness evaluation method, and the method comprises the steps: constructing a community disaster prevention toughness evaluation system under a corresponding flood disaster scene through researching the pressure element of a pressure layer U1, the state element of a state layer U2 and the response element of a response layer U3 under the flood disaster scene based on a PSR model theory; the community disaster prevention toughness evaluation method specifically comprises the following steps: step 1, analyzing toughness characteristics of communities in a city; 2, constructing a community disaster prevention toughness evaluation system; 3, performing quantitative coupling to judge the community disaster prevention toughness; 4, establishing a community disaster prevention toughness evaluation model; and 5, formulating a community disaster response feedback strategy. Therefore, according to the method, the operability of promoting tough community construction can be enhanced, the impact of flood disasters on an urban system is reduced, and the loss caused by the disasters is reduced.

Description

technical field [0001] The invention relates to the technical field of disaster prevention resilience assessment of urban community systems under rain and flood prevention scenarios, in particular to a community disaster prevention security resilience assessment method oriented to flood disasters. Background technique [0002] Resilience originated in physics and was first understood as the meaning of "returning to the original state after disturbance". Initially, the ecologist Holling integrated the resilience and stability of ecosystem behavior into the resilience model to characterize the ecological stability of the system. Against the background of changes in extreme weather and climate disasters around the world, building resilient communities has become the focus of current urban planning and management in my country. If the building of urban resilient communities is not strengthened and the ability to resist and reduce disasters is enhanced, the losses caused by natu...
