[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] At present, a lot of achievements have been made in the research of landslide susceptibility evaluation and landslide disaster risk assessment, and a series of theoretical methods and technical systems have been developed. The landslide susceptibility evaluation methods mainly include expert knowledge and statistical analysis models. Among them, the commonly used statistical analysis methods include binary statistics, hierarchical analysis method, logistic regression, artificial neural network, support vector machine, etc. Existing studies have shown that for earthquake zones in different study areas and different environmental backgrounds, various methods and models show different evaluation performance. However, the earthquake landslide susceptibility information produced by these research methods is mostly relative, and the susceptibility level does not have the real probability of earthquake landslide occurrence. To this end, a method of earthquake landslide probability combining sample collection of Bayesian probability method and machine learning model is proposed, and the real probability map of earthquake landslide is produced.

[0043] With the development of natural disaster risk assessment, landslide risk assessment has made great progress in theory and practice. Landslide risk assessment mainly analyzes the probability of landslide disasters and the hazards that may be caused under different environmental conditions, with the aim of determining the degree of harm caused by landslide disasters. In recent years, with the increasingly in-depth research on the causes and evolution of geological disasters based on remote sensing and GIS (Geographic Information System) technology, geological disaster risk assessment has shifted from early qualitative analysis to quantitative analysis, and a series of new technologies and methods have been developed. In the process of disaster risk assessment implementation, in general, a landslide disaster risk assessment system and a multi-factor evaluation model are constructed based on the specific environmental conditions of the assessment area, and the geological disaster hazard and vulnerability evaluation indicators are quantitatively analyzed, and finally the classification and zoning of disaster risk assessment are determined.

[0044] Landslide susceptibility and risk assessment is the basic work in disaster prevention and mitigation, and is also an important scientific and technological support and scientific reference for emergency rescue. After decades of development, landslide susceptibility and risk assessment has made great progress in theoretical exploration, method and technology research. However, current research lacks the necessary technical connection in the transformation and practical application of landslide susceptibility and risk assessment results, especially in the actual application of emergency rescue work in earthquake areas. There are certain defects, which are mainly reflected in:

[0045] (1) Lack of comprehensive standards for judging the susceptibility of landslides in earthquake zones and for risk classification and analysis

[0046] The existing research results on landslide susceptibility and risk assessment in earthquake zones are mostly presented in the form of regional-scale landslide susceptibility and risk levels. However, in earthquake emergency response, for earthquake zones of different magnitudes and environmental characteristics, the regional-scale earthquake landslide susceptibility and disaster risk zoning have very limited support for emergency rescue work. Certain connection standards are needed in technical and practical applications to more accurately serve earthquake emergency response.

[0047] (2) Lack of methods for rapid emergency mapping of landslide susceptibility and risk assessment in earthquake zones

[0048] After an earthquake occurs, it is the primary task to support emergency response to earthquake geological disasters by focusing on rapid response in the earthquake area in a short period of time, making rapid maps based on the landslide susceptibility and risk assessment results in the earthquake area, and providing landslide susceptibility and risk data in the earthquake area. However, on the one hand, in the absence of comprehensive judgment of landslide susceptibility and risk classification and analysis standards in earthquake areas, rapid emergency mapping products are difficult to effectively support earthquake response work. On the other hand, existing research on the transformation of results has failed to make full use of current big data analysis and network technology, thus failing to form a scientific and efficient rapid emergency mapping method.

[0049] Therefore, this application aims to improve the emergency response efficiency of earthquake geological disasters, expand the application level of geological disaster assessment scientific research results, and enhance the scientific and technological support capabilities of earthquake emergency services, and propose a landslide risk assessment and emergency mapping method for earthquake zones.

[0050] In an exemplary embodiment, Figure 1 As shown, a method for landslide risk assessment and emergency mapping in earthquake zones is provided, and the method is applied to an emergency mapping platform as an example for explanation, including the following steps:

[0051] Step 102, obtaining earthquake information of the earthquake area after the earthquake occurs.

[0052] Exemplarily, earthquake information of the earthquake area is collected immediately after the earthquake occurs.

[0053] Step 104, performing landslide risk assessment on earthquake information according to a comprehensive evaluation standard knowledge base, and obtaining landslide risk assessment information in earthquake areas; the comprehensive evaluation standard knowledge base is constructed according to comprehensive evaluation standards for landslide susceptibility and landslide risk classification in earthquake areas.

[0054] For example, the earthquake database is connected and accessed, the landslide susceptibility and risk in the earthquake area are retrieved, extracted, and calculated, and the comprehensive evaluation and judgment standard knowledge base is queried to obtain the landslide risk assessment information in the earthquake area. The comprehensive evaluation standard knowledge base is constructed based on the comprehensive evaluation standard of landslide susceptibility and landslide risk classification in earthquake areas.

[0055] For example, the seismic database adopts a lightweight model while ensuring that the data storage and management requirements of the platform are met. On the one hand, it can reduce maintenance costs, and on the other hand, it can improve the efficiency of data management.

[0056] Exemplarily, the types of data stored in the earthquake database include, but are not limited to, basic geographic information data, business model entity data (including input, output or intermediate data of each business model, etc.), user information and user behavior data (also including information communication and monitoring data between users), system configuration data (including system parameters, permission data, etc.), system log data (operation logs, error logs, etc.) and multimedia data (such as earthquake disaster site and emergency-related shared information).

[0057] For example, a modular calculation model can be used to calculate the susceptibility and risk of landslides. The model has simple and easy functions, high calculation efficiency, and can adapt to the diversity, complexity and specific scenario requirements of application scenarios.

[0058] Step 106, generating a landslide susceptibility and risk thematic map based on the landslide risk assessment information.

[0059] Exemplarily, the mapping module generates a landslide susceptibility and risk thematic map based on the landslide risk assessment information.

[0060] Step 108, generating earthquake emergency products based on the landslide susceptibility and risk thematic map.

[0061] For example, based on the thematic maps of landslide susceptibility and risk, combined with the comprehensive assessment criteria for landslide susceptibility and risk in earthquake zones, earthquake landslide emergency information is further improved and earthquake emergency products are generated, thereby achieving rapid support for earthquake emergency work.

[0062] The above-mentioned landslide risk assessment and emergency mapping method in earthquake zones provides a scientific and unified standard criterion for earthquake landslide emergency response by formulating a comprehensive evaluation standard knowledge base, greatly improving the accuracy and efficiency of emergency response; through the mapping module, it realizes the rapid collection, processing and mapping of earthquake landslide information, significantly shortening the emergency response time. At the same time, the emergency products generated by this application are not only rich in content and diverse in form, but also can closely fit the actual needs of earthquake landslide emergency response, provide comprehensive and reliable decision-making support, and realize rapid support for earthquake emergency work.

[0063] The following examples specifically illustrate the method for formulating the comprehensive evaluation criteria for landslide susceptibility and risk classification and analysis in earthquake zones of the present application.

[0064] In an exemplary embodiment, Figure 2 As shown, the above method also includes the step of constructing a comprehensive evaluation criterion, including:

[0065] Step 202, according to the magnitude of the earthquake, obtain the earthquake zone landslide risk classification evaluation standard corresponding to the magnitude of the earthquake.

[0066] Step 204, constructing a comprehensive evaluation standard knowledge base based on the comprehensive evaluation standard for landslide susceptibility and landslide risk classification in earthquake zones.

[0067] For example, the susceptibility of landslides in earthquake zones is classified into: extremely low susceptibility zone, low susceptibility zone, medium susceptibility zone, and high susceptibility zone. The susceptibility of landslides in earthquake zones presents the characteristics of multi-type cross-mixing, which can be classified into four situations: 1) earthquake zones are dominated by medium susceptibility zones and high susceptibility zones for landslides; 2) earthquake zones are dominated by medium susceptibility zones and low susceptibility zones for landslides; 3) earthquake zones are dominated by low susceptibility zones and extremely low susceptibility zones for landslides; 4) earthquake zones are dominated by extremely low susceptibility zones for landslides.

[0068] For example, the landslide risk in earthquake zones is classified into low-risk zone, medium-risk zone, and high-risk zone. Similarly, the zoning characteristics of earthquake zone risk assessment are obvious, and can be classified into four situations: 1) There are many high-risk areas in earthquake zones (high disaster risk); 2) There are many medium-risk areas in earthquake zones (high disaster risk); 3) There are scattered medium-risk areas in earthquake zones (low disaster risk); 4) The earthquake zone is basically a low-risk area (low disaster risk).

[0069] For example, the risk of landslide disasters will vary with the magnitude of the earthquake. For earthquakes of different magnitudes, the landslide risk classification evaluation criteria for earthquake zones corresponding to the magnitude of the earthquake are obtained. Further combined with expert experience and knowledge, a comprehensive evaluation standard knowledge base is constructed based on the comprehensive evaluation criteria for landslide susceptibility and landslide risk classification in earthquake zones.

[0070] In this embodiment, the evaluation criteria for landslide susceptibility and landslide risk in earthquake zones are given respectively, and combined with the earthquake magnitude and expert experience, a comprehensive evaluation standard knowledge base is jointly constructed, which provides a scientific and unified standard criterion for earthquake landslide emergency response, ensures the reliability of landslide risk assessment, and significantly improves the accuracy and efficiency of emergency response.

[0071] In an exemplary embodiment, obtaining earthquake information of an earthquake region after an earthquake occurs includes the following steps:

[0072] After an earthquake occurs, earthquake information in the earthquake area is obtained based on multi-source information channels.

[0073] Among them, earthquake information includes earthquake time, longitude and latitude of the epicenter, location, magnitude and focal depth.

[0074] For example, the channels for collecting earthquake parameters include, but are not limited to, information shared by earthquake monitoring networks, earthquake reports and parameter information released by governments or scientific research institutions, and data released by international earthquake data sharing platforms. The collection method is mainly automatic acquisition. Comprehensive collection of earthquake information ensures the comprehensiveness of comprehensive assessment of landslide susceptibility and risk in earthquake zones and emergency mapping.

[0075] The following embodiments specifically introduce the emergency mapping method of the present application.

[0076] In an exemplary embodiment, Figure 3 As shown in the figure, based on the landslide risk assessment information, generating the landslide susceptibility and risk thematic map includes the following steps:

[0077] Step 302, calling an application interface based on geographic information system technology to transmit the landslide risk assessment information to a mapping module integrated with the application interface.

[0078] Step 304, generating a landslide susceptibility and risk thematic map based on the landslide risk assessment information through a mapping module.

[0079] Exemplarily, data processing is performed based on an application interface of GIS technology to transmit landslide risk assessment information to a mapping module of an emergency mapping platform, and the mapping module is integrated with the application interface; the mapping module uses the landslide risk assessment information to generate a thematic map of landslide susceptibility and risk.

[0080] For example, the emergency mapping platform is developed based on WebGIS (the product of Internet technology applied to GIS development).

[0081] Exemplarily, the development mode of the emergency mapping platform includes but is not limited to the B / S mode (Browser / Server), and the system consists of a three-layer structure of a front-end interactive interface, a back-end logic server, and a database system.

[0082] For example, in the user management of the emergency mapping platform, multi-level permissions and multi-dimensional views can be designed for four types of users: technical personnel, business personnel, managers or decision makers. The number of user categories can be adjusted according to actual requirements to meet the diverse needs of different users for platform functions and information visualization.

[0083] Exemplarily, the functional modules of the emergency mapping platform include:

[0084] 1) Database management module: It is aimed at professional and technical personnel and is responsible for the standardized storage, processing, and standardized call of earthquake and secondary geological disaster related data.

[0085] 2) Earthquake secondary geological disaster emergency assessment module: for professional and technical personnel, to manage and apply various earthquake secondary geological disaster assessment models integrated in the platform.

[0086] 3) Rapid mapping and emergency assessment product production module: For professional and technical personnel, the module uses the result data produced by the emergency assessment module to efficiently, accurately and automatically produce thematic maps, realize the rapid production of emergency assessment products, and improve the efficiency of earthquake disaster emergency response work.

[0087] 4) Emergency product sharing and release module: for government decision makers, receiving and reviewing emergency assessment products reported by professional and technical personnel to assist emergency decision-making.

[0088] 5) Data visualization module: For all users, it provides visualization and interactive views of various types of data and information through interactive design and graphic rendering methods to assist users in understanding data and information.

[0089] 6) Decision support auxiliary module: As an extension of the auxiliary capabilities of emergency assessment products, it provides decision makers with technical support and decision support for emergency response.

[0090] In this embodiment, the emergency mapping platform takes into account the characteristics of earthquake disaster emergency response and meets the functional design requirements of high efficiency, professionalism, easy operation and standardization. In terms of technical architecture, it realizes diverse user roles and user needs and reduces the development, deployment and maintenance costs of the information platform.

[0091] In an exemplary embodiment, the development method of the application interface includes pre-calculation.

[0092] Exemplarily, the application interface based on GIS technology involves functional modules of complex computing models, and the development method includes but is not limited to using a pre-calculation method to calculate and store the necessary intermediate mapping data in advance in the database, thereby reducing the amount of calculation during application and ensuring the efficiency of mapping.

[0093] In an exemplary embodiment, the method for integrating the application interface with the mapping module is to publish the encapsulated application interface and the mapping module as a remote call technical service.

[0094] In an exemplary embodiment, the technical method for integrating the application interface with the mapping module is to deploy the application interface and the mapping module on the server side.

[0095] Exemplarily, there are two integration technologies for application interfaces and mapping modules. One is to publish the encapsulated application interfaces and mapping modules as Web (remote call technology) services, which are highly flexible and scalable, such as Django (Python Web framework), Flask (lightweight Python Web application framework) and other frameworks, supporting distributed computing and load balancing. The other is to deploy the application interface and mapping module on the server side as a component of the system logic layer, such as Java Servlet (small service program or service connector), Spring MVC (java framework), Python, etc., to achieve close integration between the modules within the system, so that high-frequency and low-latency interactions can be carried out with other modules of the mapping platform, reducing the overhead of network calls and improving the overall performance and response speed of the system.

[0096] In an exemplary embodiment, earthquake emergency products include earthquake zone landslide susceptibility and risk assessment reports, landslide susceptibility and risk thematic maps, and emergency plan recommendations; emergency product formats include paper documents, electronic documents, visual display applications, and terminal applications.

[0097] In an exemplary embodiment, Figure 4 As shown, it also includes a method for realizing visualization and function expansion, comprising the following steps:

[0098] Step 402, generating visualization and interactive views of various data and information of the landslide susceptibility and risk thematic map according to the interactive design and graphics rendering method.

[0099] Exemplarily, through interactive design and graphic rendering methods, visualization and interactive views of various types of data and information are provided to all users to assist users in understanding the data and information.

[0100] Step 404, assist in expanding the functions of earthquake emergency products and generate emergency response decision plans.

[0101] For example, as an extension of the auxiliary capabilities of emergency assessment products, it provides decision makers with technical support and decision support for emergency response.

[0102] In this embodiment, the visual interaction and decision support auxiliary functions are conducive to the rapid processing of data required for mapping, the rapid production of emergency assessment products, the provision of emergency response auxiliary solutions, and the improvement of disaster emergency response work efficiency.

[0103] Figure 5 A flow chart of a method for designing landslide risk assessment and emergency mapping in an earthquake zone is provided in an embodiment. Figure 5 , detailing the implementation steps of the method of the present application after an earthquake occurs.

[0104] In another exemplary embodiment, Figure 6 As shown, a method for landslide risk assessment and emergency mapping in an earthquake zone is provided, comprising the following steps:

[0105] Step 602, integrating earthquake early warning data access function, automatically receiving earthquake information at the first time after an earthquake occurs.

[0106] Step 604, using the earthquake secondary geological disaster emergency assessment module to promptly carry out secondary geological disaster hazard assessment and risk assessment in the earthquake zone, and can produce earthquake intensity simulation results, earthquake secondary geological disaster hazard assessment results and earthquake secondary geological disaster comprehensive risk assessment results within 5 minutes.

[0107] Step 606, using the rapid mapping and emergency assessment product production module, combined with mapping standards and comprehensive geological disaster identification standards corresponding to the assessment model, thematic maps and standardized emergency assessment products are produced within 1 minute.

[0108] Step 608, report to the emergency management department through the platform communication function or multiple channels such as e-mail, to provide auxiliary decision-making basis and technical support for earthquake secondary geological disaster risk prevention and emergency rescue.

[0109] Step 610, after review, share the emergency assessment information with relevant institutions or departments to jointly carry out earthquake disaster emergency work; make information public through the information release function of the platform to provide the public with relevant information such as earthquake secondary geological disaster risk assessment and early warning.

[0110] Taking the emergency response to a magnitude 6.8 earthquake in a certain area as an example, according to the preliminary analysis of the emergency mapping results and comprehensive evaluation criteria, the west side of the epicenter of the 6.8-magnitude earthquake is mainly a low-prone area and an extremely low-prone area for landslides and collapses, while some areas are medium-prone areas, but the east side of the epicenter is mainly a medium-prone area, and some areas are high-prone areas. The earthquake zone has a large population, mainly medium-risk areas, and scattered high-risk areas. According to factors such as the magnitude of the earthquake, the susceptibility of collapse and landslides in the earthquake zone, and the population distribution, it is preliminarily judged that the possibility of this earthquake triggering collapse and landslides is high, and the risk of co-seismic landslide disasters is high. It was later confirmed that the high-prone and high-disaster risk areas in the emergency mapping results of the present invention are indeed the areas that suffered the most serious damage due to geological disasters and the most concentrated number of deaths and missing persons in this earthquake.

[0112] Based on the same inventive concept, the embodiment of the present application also provides a system for comprehensive evaluation and emergency mapping of landslide susceptibility and risk in earthquake zones for realizing the above-mentioned method for comprehensive evaluation and emergency mapping of landslide susceptibility and risk in earthquake zones. The implementation scheme for solving the problem provided by the system is similar to the implementation scheme recorded in the above-mentioned method, so the specific limitations in the embodiments of one or more systems for comprehensive evaluation and emergency mapping of landslide susceptibility and risk in earthquake zones provided below can refer to the limitations of the method for comprehensive evaluation and emergency mapping of landslide susceptibility and risk in earthquake zones above, and will not be repeated here.
