Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cultural heritage protection, and more specifically, to a method and system for constructing a macro-scale earthquake disaster risk map of immovable cultural relics. Background Art
[0002] Earthquakes pose a severe challenge to the protection and preservation of my country's immovable cultural relics, especially the uncertainty of earthquakes, which greatly threatens the safety of these cultural relics. In my country, immovable cultural relics include ancient buildings, grottoes and stone carvings, modern and contemporary cultural relics, ancient sites and ancient tombs. They are not only large in number and diverse in type, but also in different states of preservation. Faced with natural disasters such as earthquakes, these cultural relics show different response characteristics and high vulnerability. The relevant theories of natural disaster risk assessment provide a solid theoretical support for assessing the earthquake disaster risk of immovable cultural relics. This assessment process comprehensively considers the earthquake hazard factor, that is, the probability and intensity of earthquake disasters, and the vulnerability of the disaster-bearing body, that is, the immovable cultural relics. By measuring and analyzing these key factors, we can conduct a more comprehensive and in-depth comprehensive assessment of the disaster risks that immovable cultural relics may face.
[0003] Existing earthquake disaster risk assessments for immovable cultural relics are mostly based on a certain type of immovable cultural relics. There is a lack of comprehensive assessments at the macro scale, which cannot fully consider the impact of earthquake disasters in different regions and lacks a basis for risk comparison. This restricts the formulation of preventive protection planning policies and strategies for immovable cultural relics at the macro scale and affects the scientificity and accuracy of risk decision-making.
[0004] A method for comprehensive economic risk assessment of natural disasters is proposed in the prior art, which includes: collecting data related to natural disasters in a region; generating risk assessment indicators for the region; assessing the degree of natural disaster risk that may occur in the region; creating a risk assessment technical report, a natural disaster economic growth and risk level map, and a comprehensive risk assessment result database. The drawback of this scheme is that it does not assess the risk caused by natural disasters to a certain macro-thing, and lacks similar comparisons, so the risk assessment value is low.
[0005] To this end, in combination with the above requirements and the defects of the prior art, the present application proposes a method and system for constructing a macro-scale earthquake disaster risk map of immovable cultural relics. Summary of the invention

[0043] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0044] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.
[0045] Example 1
[0046] like Figure 1 As shown, the present invention provides a method for constructing a macro-scale earthquake disaster risk map of immovable cultural relics, and the method comprises the following steps:
[0047] S1. Collect data related to earthquakes and immovable cultural relics, and conduct earthquake hazard analysis and cultural relic vulnerability analysis on the collected data.
[0048] S2. Construct a risk assessment matrix based on the impact of historical disasters on immovable cultural relics on different vulnerabilities.
[0049] S3. Input immovable cultural relics as the assessment object, and output the macro-scale immovable cultural relics earthquake disaster risk map according to the risk assessment matrix output results and the preset risk map parameters.
[0050] In step S1, the relevant data of earthquakes and immovable cultural relics include: earthquake hazard factor data and immovable cultural relics information data, and earthquake hazard analysis is performed on the earthquake hazard factor data to obtain the earthquake hazard level within a preset geographical range; data screening and cultural relic vulnerability analysis are performed on the immovable cultural relics information data to output the vulnerability level of the immovable cultural relics.
[0051] Among them, earthquake hazard factor data refers to a series of factors used to assess the disasters that earthquakes may cause, including but not limited to the frequency, intensity, focal depth, distribution of seismic faults, geological structure, etc. These data are crucial to understanding the earthquake disaster risks that may be suffered in a specific area and are the basis for earthquake disaster risk assessment.
[0052] In a specific embodiment, step S1 includes processing information data of immovable cultural relics and cultural heritage protection units to ensure risk assessment requirements and data validity, and collecting earthquake hazard factor data within a preset geographical range to construct an immovable cultural relic earthquake hazard factor database.
[0053] The specific process of the earthquake hazard analysis is as follows: collecting earthquake hazard factor data in the study area, including regional seismic intensity data with a probability exceeding 10% in a preset year, specifically peak ground acceleration and spatial distribution data of landform types; performing spatial projection, correction and coordinate transformation of the data in a geographic information system platform, and constructing an earthquake hazard factor database for immovable cultural relics; determining the direct hazard level of the earthquake based on the peak ground acceleration, and using regional environmental data to make hazard corrections, and calculating the corrected hazard level.
[0054] In a specific embodiment, the preset year is 50 years.
[0055] It should be noted that the regional seismic intensity data with a probability of exceeding 10% means that within a preset time period, there is a 10% probability of occurring or exceeding a certain level of seismic intensity. It is usually used in earthquake engineering and risk assessment to determine the seismic hazard of a specific area and the seismic design standards of buildings; the peak ground acceleration (PGA) is an important parameter in earthquake engineering, which is used to describe the maximum acceleration of ground motion during an earthquake.
[0056] Among them, the Geographic Information System platform, or GIS platform, is a system for capturing, storing, analyzing, and managing geospatial data. It allows users to visualize, query, edit, analyze, and map geographically distributed data. The GIS platform is capable of processing geographic data, which can be topography, location of buildings, demographic information, climate patterns, etc. The GIS platform is widely used in urban planning, environmental management, transportation and logistics, public safety, natural resource protection, agriculture, geological exploration, market analysis, and other fields. The use of the GIS platform includes: spatial projection, data correction, coordinate conversion, and database construction.
[0057] The spatial projection refers to the process of projecting geographic data to a preset area, which is used to ensure the accuracy of maps and geographic data, especially when data from different sources need to be integrated together. The data correction involves adjusting the accuracy and quality of geographic data to ensure that the data reflects the characteristics of the real world. The coordinate conversion is the process of converting geographic data from one coordinate system to another, which is used to convert geographic coordinate systems (latitude and longitude) to plane coordinate systems (such as UTM, etc.). The database construction: In the GIS platform, the construction of the database is specifically to organize and store data so that it can be effectively queried and analyzed. For the earthquake hazard factor database of immovable cultural relics, it includes the location of the cultural relics, structural characteristics, earthquake risk assessment data, etc.
[0058] As shown in Table 1, the direct hazard levels are:
[0059]
[0060] in, , , , and They represent low, lower, medium, higher and high levels of immediate risk respectively.
[0061]
[0062] The regional environmental data is the earthquake amplification factor , which is used to characterize the amplification level of earthquake risk in different regions. They represent the low, lower, higher and high amplification levels of the earthquake amplification factor to earthquake hazard respectively.
[0063] Table 1 Modified hazard level classification
[0064]
[0065] According to Table 1, the direct risk level of earthquake is corrected by using the regional environmental data to obtain the corrected risk level:
[0066]
[0067] in, Indicates the modified hazard level, Indicates the immediate danger of an earthquake. represents the earthquake amplification factor, h’ For the direct hazard level, s is the terrain amplification factor level, Indicates the corresponding hazard level h’ and terrain amplification factor level s The corresponding modified hazard level.
[0068] As shown in Table 2, the vulnerability levels are:
[0069]
[0070] Where, represents the vulnerability level, , , , and They represent the vulnerability levels as low, lower, medium, higher and high respectively.
[0071] Furthermore, the vulnerability is calculated using the following formula:
[0072]
[0073] in, is the actual vulnerability level of different vulnerability indicators, such as current quality, number of units, area, etc. It is the vulnerability level in risk assessment. The actual vulnerability level of the different vulnerability indicators is obtained according to the data information of the cultural relics protection unit of the immovable cultural relics to be assessed, and the indicator data with the highest vulnerability is taken as the vulnerability level. .
[0074] Table 2 Risk Level classification
[0075]
[0076] According to Table 2, in step S2, the specific process of constructing the risk assessment matrix is: combining the impact of historical disasters of immovable cultural relics on the vulnerability levels of different immovable cultural relics, construct the following risk assessment matrix:
[0077]
[0078] in, Indicates the earthquake risk of immovable cultural relics. r is the risk level, h To correct the danger, v For vulnerability.
[0079] The preset risk map parameters in step S3 include: risk classification colors, map elements and drawing elements, the map elements include map base map data information and map size, and the drawing elements include legends and annotation information.
[0080] In a specific embodiment, the image element is as follows: Figure 2-Figure 5 As shown, it includes title, subtitle, legend, scale, annotation information and signature column / preparing unit, etc.
[0081] The specific process of step S3 is: inputting immovable cultural relics as the assessment object, collecting the location, preservation status and area of the assessment object, conducting a vulnerability analysis, combining the historical disaster information within the preset geographical range, and processing using the risk assessment matrix to obtain the earthquake risk R of the immovable cultural relics; according to the preset risk map parameters, outputting a risk map including the specific terrain of the preset geographical range and the earthquake risk of the immovable cultural relics.
[0082] In a specific embodiment, the output risk map is as follows: Figure 2 - Figure 4 shown.
[0083] According to the above technical features, the present invention adopts the regional seismic intensity under the scenario of 10% exceedance probability in 50 years as the hazard index, considers the terrain factors to amplify the hazard, and classifies them with reference to the vulnerability indicators of immovable cultural relics and cultural relics protection units. The risk matrix is used to conduct macro-scale risk assessment, and the relevant results can provide support for the formulation of preventive protection plans for immovable cultural relics and decision-making plans for protection projects.
[0084] Example 2
[0085] Based on the above embodiment 1, combined with Figure 2 - Figure 4This embodiment takes ancient buildings, grottoes and stone carvings as cultural relics protection units in a provincial area as the objects, and conducts an operational example verification of the method for constructing a macro-scale earthquake disaster risk map of immovable cultural relics.
[0086] In a specific embodiment, during the hazard analysis and vulnerability analysis, the regional seismic intensity data (PGA) of a provincial region under a 50-year exceedance probability of 10% and the spatial distribution data of China's 1:1 million landform types are first collected; and the data are spatially projected, corrected, and coordinate converted in the GIS platform. The natural disaster risk map presented by the regional seismic intensity data (PGA) is as follows: Figure 2 The spatial distribution data of landform types are shown in Figure 3 shown.
[0087] Import the hazard data into the hazard factor database; determine the earthquake hazard level according to PGA, where 0.05g is assigned to low hazard, 0.10g / 0.15g is assigned to lower hazard, 0.20g is assigned to medium hazard, 0.30g is assigned to higher hazard, and 0.40g is assigned to high hazard. Figure 2 The colors blue, green, yellow, orange and red are used to represent them respectively.
[0088] The earthquake hazard amplification level is determined based on the spatial distribution data of landform types at a scale of 1:1 million in a provincial area. The mountain amplification level is assigned a low value, the plain amplification level is assigned a low value, the hill amplification level is assigned a high value, and the platform amplification level is assigned a high value. Figure 3 Dark green, green, light green, yellow, orange-yellow, orange and red are used to represent the hazard levels. The revised hazard levels are given according to Table 1.
[0089] This paper analyzes the vulnerability of ancient buildings, grottoes, and stone carvings in a certain provincial area. First, the cultural relics survey data of ancient buildings, grottoes, and stone carvings in a certain provincial area are collected; the information of the obtained immovable cultural relics data is screened, space vectorized, space projected, calibrated, and coordinate converted.
[0090] The processed immovable cultural relics data are imported into the disaster-prone body database, and the indicators of the current quality, number of units, and area of the cultural relics protection units are graded, and the vulnerability calculation is performed. The vulnerability level is obtained according to Table 2.
[0091] According to the risk assessment matrix, combined with the impact of historical disasters on different vulnerabilities of immovable cultural relics, a risk assessment matrix was constructed and earthquake risk was assessed. The specific assessment results are shown in Tables 3 and 4.
