[0022] exist Figure 1 In the urban geological hazard resilience level assessment device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the urban geological hazard resilience level assessment device of the present invention can be set in the urban geological hazard resilience level assessment device, and the urban geological hazard resilience level assessment device calls the urban geological hazard resilience level assessment program stored in the memory 1005 through the processor 1001, and executes the urban geological hazard resilience level assessment method provided by the embodiment of the present invention.

[0023] The embodiment of the present invention provides a method for evaluating the resilience level of urban geological hazards, referring to Figure 2 , Figure 2 This is a flow chart of the first embodiment of the urban geological hazard resilience level assessment method of the present invention.

[0024] In this embodiment, the urban geological disaster resilience level assessment method includes the following steps: Step S10: Determine a plurality of geological disaster assessment indicators corresponding to each district and county based on the geological disaster information of the city.

[0025] It is easy to understand that the execution entity of this embodiment can be an urban geological hazard resilience level assessment system with functions such as data processing, network communication and program running, or other computer equipment with similar functions, etc. This embodiment is not limited.

[0026] Furthermore, the processing method for determining multiple geological disaster assessment indicators corresponding to each district and county based on the city's geological disaster information is as follows: determining the geological disaster threat information, urban disaster bearing capacity information and disaster management capacity information corresponding to each district and county based on the city's geological disaster information; extracting multiple geological disaster characteristic data corresponding to each district and county from the geological disaster threat information, urban disaster bearing capacity information and disaster management capacity information; and determining multiple geological disaster assessment indicators corresponding to each district and county based on the multiple geological disaster characteristic data corresponding to each district and county.

[0027] It should be noted that geological disaster threat information includes disaster susceptibility information and meteorological conditions. Disaster susceptibility information includes the density of potential collapse, landslide, and debris flow risk points, and meteorological conditions include the number of days with heavy rain and rainfall.

[0028] The city's disaster bearing capacity information includes economic level information, infrastructure information and social security information. The economic level information can be per capita GDP, the infrastructure information can be the coverage rate of shelters, and the social security information can be the density of medical resources.

[0029] Disaster management capacity information includes the completeness of the early warning system, emergency team construction, and public education investment.

[0030] Furthermore, the processing method for determining multiple geological disaster assessment indicators corresponding to each district and county based on multiple geological disaster characteristic data corresponding to each district and county is to construct an assessment indicator system corresponding to each district and county based on multiple geological disaster characteristic data corresponding to each district and county, and the assessment indicator system is constructed by a pressure layer, a state layer and a response layer; based on the pressure layer, the state layer and the response layer, the multiple geological disaster assessment indicators corresponding to each district and county are determined.

[0031] In its implementation, an assessment indicator system was constructed based on the pressure-state-response framework. Each district and county has multiple geological hazard assessment indicators, including those for the pressure layer, the state layer, and the response layer. The pressure layer includes indicators for disaster susceptibility and meteorological conditions; the state layer includes indicators for economic development, infrastructure, and social security; and the response layer includes indicators for the completeness of the early warning system, emergency response team development, and public education investment.

[0032] The disaster susceptibility index can be expressed as:

[0033] Meteorological condition indicators can be expressed as: P 2 = Average number of rainy days per year P 3 = average annual rainfall The economic level indicator can be expressed as:

[0034] Infrastructure indicators can be expressed as: Social security indicators can be expressed as: The early warning system perfection index can be expressed as: R 1 = Early warning system coverage The emergency team construction indicators can be expressed as:

[0035] The public education investment index can be expressed as:

[0036] Step S20: Calculate the indicator weights corresponding to each geological disaster assessment indicator based on the analytic hierarchy process and the entropy weight method.

[0037] Furthermore, the processing method for calculating the indicator weights corresponding to each geological hazard assessment indicator based on the hierarchical analysis method and the entropy weight method is to perform range standardization processing on multiple geological hazard assessment indicators of each district and county based on the hierarchical analysis method to obtain the standardized indicator values ​​corresponding to each geological hazard assessment indicator; according to the standardized indicator values ​​corresponding to each geological hazard assessment indicator, the information entropy of each geological hazard assessment indicator is calculated by the entropy weight method; based on the information entropy of each geological hazard assessment indicator, the indicator weights corresponding to each geological hazard assessment indicator are calculated.

[0038] In this embodiment, the range method is used to normalize the positive and negative indicators, and the weight of each indicator is determined based on the entropy weight method combined with the Analytic Hierarchy Process (AHP) to ensure the objectivity and scientific nature of the indicator weight and eliminate subjective bias.

[0039] It should also be noted that the positive and negative indicators can be set by the user according to actual conditions. In this embodiment, the indicator corresponding to the pressure layer can be used as a negative indicator, and the indicators corresponding to the state layer and the response layer can be used as positive indicators.

[0040] Range method standardization processing: For positive indicators: For negative indicators:

[0041] in, is the jth original index value of a certain layer in the i-th district or county, is the normalized index value (range 0, 1).

[0042]

[0043] Normalized matrix:

[0044] Calculate the proportion of each district and county in each indicator:

[0045] Calculate information entropy: ,

[0046] Where n is the number of districts and counties.

[0047] Furthermore, the weights of the indicators corresponding to the geological disaster assessment indicators are calculated based on the information entropy of the geological disaster assessment indicators. The index difference coefficients of the geological disaster assessment indicators (i.e., 1-H j ); Calculate the indicator weights corresponding to the geological disaster assessment indicators of each place according to the indicator difference coefficient of each place.

[0048] Calculate the weight of each indicator:

[0049] Where m is the number of indicators.

[0050] Step S30: Calculate the index closeness of each district and county respectively by using the TOPSIS method according to the multiple geological hazard assessment indicators corresponding to each district and county and the indicator weights corresponding to each geological hazard assessment indicator.

[0051] Furthermore, the indicator closeness of each district and county is calculated respectively according to the multiple geological hazard assessment indicators corresponding to each district and county and the indicator weights corresponding to each geological hazard assessment indicator through the approximate ideal solution ranking method or the superior and inferior solution distance method (Technique for Order Preference by Similarity to Ideal Solution TOPSIS). The processing method is to determine the maximum and minimum values ​​of the multiple geological hazard assessment indicators corresponding to each district and county respectively; based on the TOPSIS method, the indicator ideal solution and the indicator negative ideal solution are constructed according to the maximum and minimum values ​​of each geological hazard assessment indicator; and the indicator closeness of each district and county is calculated according to the indicator ideal solution, the indicator negative ideal solution and the indicator weights corresponding to each geological hazard assessment indicator.

[0052] In the specific implementation, the entropy weight-TOPSIS method is used to quantitatively evaluate the level of urban geological disaster resilience, calculate the closeness of each district and county to the ideal solution (T value), and divide the resilience levels (high, relatively high, medium, relatively low, and low).

[0053] Calculate closeness: The ideal solution is a hypothetical solution where each evaluation metric takes the most favorable and ideal value. As the optimal benchmark for evaluation, the closer the evaluation object is to the ideal solution, the better its performance or status.

[0054] A negative ideal solution is a virtual solution where each of the evaluation indicators takes the most unfavorable and undesirable value. As the worst benchmark for evaluation, the further the evaluation object moves from the negative ideal solution, the better its performance or status.

[0055] By calculating the distance between each indicator and the ideal solution and the negative ideal solution, the comprehensive resilience level of the city's geological disaster resilience level is obtained.

[0056] Determine the ideal solution (i.e., the index ideal solution) and the negative ideal solution (i.e., the index negative ideal solution): Ideal solution:

[0057] For each indicator x j : If it is a benefit indicator (the bigger the better), then .

[0058] If it is a cost-type indicator (the smaller the better), then .

[0059] Negative ideal solution:

[0060] For each indicator x j : If it is a benefit indicator (the smaller the better), then .

[0061] If it is a cost-type indicator (the larger the better), then .

[0062] Furthermore, the index closeness of each district and county is calculated based on the index ideal solution, the index negative ideal solution and the index weight corresponding to each geological disaster assessment index. The ideal weighted Euclidean distance and negative ideal weighted Euclidean distance of each district and county are calculated based on the index weight corresponding to each geological disaster assessment index according to the index ideal solution and the index negative ideal solution and the standardized index value corresponding to each geological disaster assessment index. The indicator closeness of each district and county is calculated based on the ideal weighted Euclidean distance and negative ideal weighted Euclidean distance of each district and county.

[0063] Calculate the weighted Euclidean distance between each evaluation object (i.e. each district and county) and the ideal solution and the negative ideal solution: The distance to the ideal solution (i.e., the ideal weighted Euclidean distance):

[0064] The distance to the negative ideal solution (i.e., the negative ideal weighted Euclidean distance):

[0065] Calculate the indicator closeness:

[0066] Where C i is the indicator closeness of the i-th district or county.

[0067] Step S40: Evaluate the geological disaster resilience level of the city based on the indicator proximity of each district and county.

[0068] In the specific implementation, according to the indicator closeness C i Determine the toughness level.

[0069]

[0070] In this embodiment, first, multiple geological disaster assessment indicators corresponding to each district and county are determined based on the geological disaster information of the city. Then, the indicator weights corresponding to each geological disaster assessment indicator are calculated based on the hierarchical analysis method and the entropy weight method. Then, the indicator closeness of each district and county is calculated based on the multiple geological disaster assessment indicators corresponding to each district and county and the indicator weights corresponding to each geological disaster assessment indicator using the TOPSIS method. Finally, the city's geological disaster resilience level is evaluated based on the indicator closeness of each district and county. Compared with the existing technology that focuses on a single type of disaster or static indicators, resulting in insufficient comprehensiveness and strong subjectivity, this embodiment quantitatively evaluates the city's geological disaster resilience level by constructing a scientific and reasonable evaluation index system, thereby providing a scientific basis and decision-making support for urban geological disaster prevention and control.
