Description

Technical Field

[0001] The present invention belongs to the technical field of spatial planning assessment, and specifically relates to a national land space planning risk assessment system and method. Background Art

[0002] With the acceleration of urbanization and the rapid development of social economy, land use and urban planning are crucial to achieving sustainable development. There are various risks in national land space planning, such as the possibility of natural disasters in the future and the uncertainty of environmental impacts, which require risk assessment and planning. National land space planning is an important decision involving the long-term future. Various risk factors need to be considered to improve the scientificity and rationality of the planning. Through risk assessment systems and methods, planners can better understand potential risks and reduce the risks of planning decisions. Through national land space planning risk assessment, potential disaster risks can be identified in advance, corresponding risk management strategies and measures can be formulated, and disaster losses can be reduced.

[0003] The current field of land and space planning risk assessment faces some challenges, which are mainly manifested in the following aspects: First, traditional assessment methods often cannot provide sufficiently accurate results, and the assessment errors are large. Second, the existing planning assessment process is relatively long, which is not conducive to rapid response to planning needs. In addition, existing methods usually lack multi-dimensional comprehensive assessment capabilities, which limits the comprehensiveness and depth of the assessment results. Since land and space planning risk assessment is highly dependent on a large amount of data, the incompleteness or inaccuracy of the data will directly affect the accuracy and credibility of the assessment. At present, many land and space planning risk assessment systems tend to assess a single risk type and fail to fully realize multi-dimensional comprehensive assessment. Given that land and space planning risks are affected by a combination of factors, it is urgent to build a multi-dimensional assessment system that can comprehensively consider various risk factors to improve the accuracy and practicality of the assessment.

[0021] Example 1 like Figure 1As shown, a national land space planning risk assessment system includes an ecological planning space risk characteristic value acquisition module, an energy planning space risk characteristic value acquisition module, a transportation space planning risk characteristic value acquisition module and a national land space planning adjustment module.

[0022] The module for acquiring the spatial risk characteristic value of ecological planning is used to acquire the national ecological spatial planning data set. Based on the acquired national ecological spatial planning data set, a comprehensive analysis is performed to obtain the spatial risk characteristic value of national ecological planning.

[0023] The specific analysis process is as follows: obtain the national ecological space planning data set, which specifically includes the area of ​​ecological protection areas in the national ecological space planning, the area of ​​ecological restoration areas in the national ecological space planning, and the area of ​​vegetation in the national ecological space planning; Ecological protection areas are areas established to maintain the integrity of ecosystems and biodiversity, protect rare and endangered species and important ecosystem functions. The area of ​​ecological protection areas refers to the total area of ​​the areas designated as ecological protection areas within the planning scope, and is an important protection area for protecting biodiversity and ecosystems; ecological restoration areas refer to areas where ecological environment degradation or damage caused by human development and utilization requires ecological restoration and recovery. The area of ​​ecological restoration areas refers to the total area of ​​the areas designated as ecological restoration areas within the planning scope, and is used to guide the restoration and construction of the ecological environment and improve the quality of the ecological environment; vegetation area refers to the total area covered with vegetation within the planning scope, including different types of vegetation such as forests, grasslands, and wetlands. The size of the vegetation area directly reflects the ecological environment quality and vegetation coverage within the planning area, and is an important indicator for evaluating the health and stability of the ecosystem; Based on the acquired national land ecological space planning data set, a comprehensive analysis is conducted to obtain the spatial risk characteristic values ​​of the national land ecological planning. The spatial risk characteristic values ​​of the national land ecological planning are used as the analysis basis for risk assessment of the national land space planning.

[0024] The area of ​​ecological protection areas, as an indicator for protecting biodiversity and important functional areas of ecosystems, generally includes various types of vegetation coverage areas, such as forests, wetlands, grasslands, etc. The increase in the area of ​​ecological protection areas can promote the protection and restoration of vegetation, which is beneficial to increasing the vegetation area and maintaining the stability of vegetation coverage; the area of ​​ecological restoration areas, as areas that need to be restored due to ecological environment deterioration caused by human activities, usually needs to improve the quality of ecological environment through vegetation restoration and recovery. The increase in vegetation area in ecological restoration areas can not only promote the progress of ecological restoration work, but also improve the degree and quality of vegetation coverage, thereby improving the health of the ecosystem; the area of ​​ecological protection areas and the area of ​​ecological restoration areas together constitute the ecological protection and restoration network in the national ecological space planning. Through scientific and reasonable planning and management of these two areas, a complete ecosystem protection and restoration system can be formed; the vegetation area, as the foundation and core element of the entire system, integrates vegetation restoration and protection into ecological protection areas and ecological restoration areas to achieve a dual improvement in vegetation coverage and ecological environment quality.

[0025] By obtaining and comprehensively analyzing the national land ecological space planning data set, we can understand the important parameters such as the area of ​​ecological protection areas, ecological restoration areas and vegetation areas in the national land ecological space planning.

According to the problems identified in the ecological risk characteristic value, reasonable ecological planning strategies and measures can be formulated to promote the continuous improvement of the ecological environment and the protection of the ecosystem; the ecological planning spatial risk characteristic value obtained by comprehensive analysis of the national land ecological space planning data set can help monitor and evaluate the implementation effect of the ecological planning and achieve the ecological goals; adjust the ecological planning according to the evaluation results, guide relevant parties to better fulfill their ecological protection and ecological restoration responsibilities, and help achieve the long-term sustainable development goals of the national land ecological space planning; based on the ecological planning spatial risk characteristic value, the adaptability of the national land space planning to the ecological environment can be enhanced, the planning can be adjusted in time, the ecosystem can be protected, the challenges of the ecological environment can be effectively responded to, and the ecological sustainable development of the national land space planning can be promoted.

[0026] By obtaining the national land ecological space planning data set, comprehensively analyzing the spatial risk characteristic values ​​of the national land ecological planning, obtaining the national land ecological space planning data set, and systematically collecting various data related to the ecological environment, a comprehensive assessment of the national land ecological space can be achieved, and the risk characteristics of the national land ecological planning space can be identified more comprehensively and accurately, providing a scientific basis for subsequent decision-making; the information in the national land ecological space planning data set not only helps to assess the current risk situation, but also provides support for future sustainable development planning, and evaluates and analyzes ecological and environmental factors, which can provide a scientific and sustainable direction for future national land space planning.

[0027] The calculation formula for the spatial risk characteristic value of national ecological planning is: ; In the formula, α is the spatial risk characteristic value of the national land ecological planning, BS is the area of ​​the ecological protection zone of the national land ecological space planning, XS is the area of ​​the ecological restoration zone of the national land ecological space planning, ZS is the vegetation area of ​​the national land ecological space planning, BS0 is the area of ​​the ecological protection zone defined by the national land ecological space stored in the database, XS0 is the area of ​​the ecological restoration zone defined by the national land ecological space stored in the database, and ZS0 is the reference vegetation area of ​​the national land ecological space stored in the database. is the compensation factor of the set BS, is the compensation factor of the set XS, is the compensation factor of the set ZS.

[0028] Monitoring and evaluating the area of ​​ecological protection areas can timely discover and solve the problems of ecological environment damage, protect precious ecological resources and maintain ecological balance; the area of ​​ecological restoration areas reflects the degree of repair and recovery of the damaged ecosystem. By calculating the area of ​​ecological restoration areas, the progress and effect of ecological restoration work can be evaluated, and the damaged ecosystem can be further improved; vegetation area is an important part of the ecosystem. By monitoring and evaluating the changes in vegetation area, the ecological environment status of different regions can be understood, and ecological planning and resource allocation can be adjusted in time to protect and promote the healthy development of vegetation; The spatial risk characteristic values ​​of national land ecological planning can accurately assess the risk level of national land ecological planning by comprehensively considering factors such as ecological protection areas, ecological restoration areas and vegetation areas, provide a basis for planning adjustments and risk warnings, and help to promptly discover and resolve existing ecological risk problems; monitoring and evaluating the spatial risk characteristic values ​​of national land ecological planning can ensure the continuous improvement of the ecological environment and the sustainable use of resources, thereby promoting national land ecological planning to develop in the direction of eco-friendly and sustainable development; through field investigations of national land ecological space, detailed measurements, inspections and evaluations of ecological protection areas, ecological restoration areas, vegetation areas, etc. are carried out to obtain accurate data, remote sensing technology is used to obtain high-resolution satellite images, ecological protection areas, ecological restoration areas and vegetation coverage in different regions are interpreted, and relevant area information is extracted. With the help of geographic information system technology, data processing, spatial analysis and graphical display of various indicators of national land ecological space can be carried out to achieve comprehensive data utilization and planning management.

[0029] The preset national ecological space is obtained from the database to define the ecological protection area, ecological restoration area, and reference vegetation area. The ecological service value of the ecological protection area, ecological restoration area, and vegetation is quantitatively evaluated through ecosystem service value assessment methods, such as market value method, replacement cost method, conditional value method, etc., and then the compensation factor is determined. Experts in this field are invited to provide consultation and demonstration to ensure the scientificity and rationality of the compensation factor.

[0030] The energy planning spatial risk characteristic value acquisition module is used to obtain the national land energy spatial planning data set, and based on the acquired national land energy spatial planning data set, a comprehensive analysis is performed to obtain the national land energy planning spatial risk characteristic value.

[0031] The specific analysis process is as follows: obtain the national land energy space planning data set, which specifically includes the annual extraction of traditional energy in the national land energy space planning, the traditional energy reserves in the national land energy space planning, and the annual use of new energy in the national land energy space planning; The annual extraction of traditional energy in the national land and energy space planning refers to the total amount of traditional energy extracted within the scope of the national land and energy space planning within one year, reflecting the actual extraction of traditional energy resources in the national land and space, and is of great significance for evaluating the stability of energy supply, resource utilization efficiency and environmental impact; the traditional energy reserves in the national land and energy space planning refer to the total reserves of traditional energy within the scope of the national land and space planning. Traditional energy reserves refer to the amount of resources that can be mined under current technical and economic conditions, and are an important measurement indicator of traditional energy resources in the national land and space; the annual use of new energy in the national land and energy space planning refers to the total amount of new energy used within the scope of the national land and space planning within one year. The annual use of new energy reflects the utilization of new energy resources in the national land and space, and plays an important role in promoting the development of clean energy, reducing dependence on traditional energy and reducing carbon emissions; Based on the acquired national land and energy spatial planning dataset, a comprehensive analysis is conducted to obtain the spatial risk characteristic values ​​of national land and energy planning, which are used as the analysis basis for risk assessment of national land and energy spatial planning.

[0032] An increase in mining volume may lead to a decrease in reserves, especially when resources are depleted during the mining process. An increase in traditional energy mining may compete with the use of new energy and may also affect the environment, thereby affecting the development and utilization of new energy. The abundance of traditional energy reserves may affect the development of new energy, because the abundance of resources may reduce the demand for new energy, but at the same time it may also provide transitional energy during the transition period.

[0033] The spatial risk characteristic values ​​of national land and energy planning can provide scientific data support for decision makers, help them better formulate national land and energy planning policies, and reduce risks in the process of resource exploitation and utilization. These characteristic values ​​can serve as an important basis for risk assessment of national land and space planning, and help assess the risk level of energy resource exploitation and utilization within the national land space, so as to take corresponding risk management measures. Through the analysis of the spatial risk characteristic values ​​of national land and energy planning, we can better guide national land and space planning to develop in the direction of sustainable development, balance the relationship between resource utilization and environmental protection, and achieve sustainable utilization of resources.

[0034] The calculation formula for the spatial risk characteristic value of national land energy planning is: ; Where β is the spatial risk characteristic value of national energy planning, KC is the annual extraction of traditional energy in national energy space planning, CL is the traditional energy reserves in national energy space planning, XY is the annual use of new energy in national energy space planning, KC0 is the annual extraction of traditional energy defined in national energy space stored in the database, CL0 is the traditional energy reserves of national energy space reference stored in the database, XT0 is the annual use of new energy defined in national energy space stored in the database, is the compensation factor of the set KC, is the compensation factor of the set CL, is the compensation factor of the set XY, and e is a natural constant.

[0035] Calculating spatial risk characteristic values ​​can comprehensively evaluate the extraction, reserves and usage of national energy resources, identify potential risk factors, and help timely discover and respond to possible problems; based on the calculation results of spatial risk characteristic values, relevant departments and institutions can make scientific plans and decisions, reasonably arrange the extraction and utilization of traditional energy, promote the development and utilization of new energy, and achieve sustainable utilization of energy resources; analysis of traditional energy extraction and reserves can help achieve optimal resource allocation, reasonably allocate and utilize energy resources within the country, and improve resource utilization efficiency; Comprehensive consideration of factors such as the annual use of new energy can promote environmental protection and ecological balance, reduce the impact on the environment, and promote the adjustment and optimization of the energy structure; based on the calculation results of the spatial risk characteristic value, a sound risk management and early warning mechanism can be established to respond to potential energy risks in a timely manner and ensure the security and stable supply of national energy; the annual extraction of traditional energy in the national energy space planning is obtained through statistical data from the energy department, reports from energy production enterprises, and local annual energy extraction plans; the traditional energy reserves in the national energy space planning are obtained through geological exploration reports, mineral resource assessment reports, and reserve data from the energy department, and the annual use of new energy in the national energy space planning is obtained through statistical data on new energy power generation, new energy utilization planning reports, and new energy development plans from the energy department. You can query databases for data such as the annual extraction of traditional energy defined in the national land and energy space, including databases of the national energy department, mineral resources databases, databases of geological exploration institutions, etc. You can query databases for data such as traditional energy reserves defined in the national land and energy space, including databases of mineral resources databases, databases of geological exploration institutions, etc. You can query databases for data such as the annual usage of new energy defined in the national land and energy space, including databases of new energy power generation statistics, databases of new energy development plans, etc.

[0036] The compensation factors for the annual extraction of traditional energy in the national land energy space planning are set through energy demand forecasting, resource extraction cost assessment and other analyses to determine appropriate compensation factors. The compensation factors for traditional energy reserves in the national land energy space planning are set through geological exploration results analysis, resource reserve surveys and other studies to determine appropriate compensation factors. The compensation factors for the annual use of new energy in the national land energy space planning are set through new energy technology maturity assessment, market demand forecasting and other studies to determine appropriate compensation factors.

[0037] The module for acquiring risk characteristic values ​​of transportation space planning is used to acquire the data set of national land transportation space planning. Based on the acquired data set of national land transportation space planning, a comprehensive analysis is performed to obtain the risk characteristic values ​​of national land transportation space planning.

[0038] The data set of land and transportation spatial planning includes the load flow of the transportation network in the land and transportation spatial planning, the total length of railway facilities in the land and transportation spatial planning, and the daily flow limit of urban roads in the land and transportation spatial planning. The load flow of the transportation network in the land and transportation spatial planning indicates the traffic flow carried on the transportation network in the land and transportation spatial planning. The load flow of the transportation network refers to the number of vehicles or traffic flow passing through the transportation network in a certain period of time, which reflects the usage and carrying capacity of the transportation network and is of great significance for evaluating the degree of traffic congestion, planning transportation infrastructure, and optimizing traffic flow. The total length of railway facilities in the land and transportation spatial planning indicates the total length of the railway network in the land and transportation spatial planning. The total length of railway facilities refers to the cumulative length of railway lines within the land and transportation spatial planning, including various types of railway facilities such as high-speed railways and ordinary railways. The total length of railway facilities reflects the coverage and scale of the railway transportation network and plays an important role in promoting the development of railway transportation and improving transportation efficiency. The daily flow limit of urban roads in the land and transportation spatial planning indicates the average daily flow limit on urban roads. The daily flow limit of urban roads refers to the maximum number of vehicles passing through urban roads every day, which is used to control road traffic flow, maintain traffic order and safety, and is of great significance for urban traffic management, road planning, and traffic congestion relief.

[0039] The construction and coverage of railway facilities will have an impact on the load flow of the transportation network. As an important mode of transportation, railways can share the road traffic load and reduce road traffic congestion. The increase in the total length of railway facilities may reduce the load flow of the road traffic network and improve the operating efficiency of the overall transportation system. The daily limit flow of urban roads directly affects the load flow of the transportation network. When the daily limit flow of urban roads is small, it may cause traffic congestion and increase the load flow of the transportation network. Reasonable setting of the daily limit flow of urban roads can help control traffic congestion and reduce the load flow of the transportation network. The construction and improvement of railway facilities can reduce dependence on urban roads and reduce the load flow and daily limit flow of urban roads. As an efficient mode of transportation, railways can share the traffic pressure of urban roads and reduce road traffic congestion, thereby affecting the daily limit flow of urban roads.

[0040] Based on the acquired spatial data set of land and transportation planning, a comprehensive analysis is performed to obtain the risk characteristic values ​​of land and transportation spatial planning. The specific analysis process is: based on the acquired spatial data set of land and transportation planning, a comprehensive analysis is performed to obtain the risk characteristic values ​​of land and transportation spatial planning. The risk characteristic values ​​of land and transportation spatial planning are used as the analysis basis for risk assessment of land and transportation spatial planning.

[0041] Risk assessment based on actual data can provide a scientific basis for land and transportation planning, help planners identify risks more accurately and take corresponding decision-making measures. By analyzing the risk characteristic values, problems and bottlenecks in transportation planning can be discovered, resources can be allocated in a targeted manner, and planning efficiency and effectiveness can be improved. Early detection of potential risks can help planners adjust measures in a timely manner to avoid the expansion of risks and the impact on the safe and stable development of land and transportation. Continuously analyzing and evaluating the risk characteristic values ​​of land and transportation spatial planning can continuously improve planning schemes and improve the sustainability and stability of planning.

[0042] By obtaining the national land and transportation spatial planning data set and conducting a comprehensive analysis to obtain the risk characteristic value of the national land and transportation spatial planning, the national land and transportation spatial planning data set can systematically collect various data related to transportation development, including road network conditions, traffic flow, distribution of transportation facilities and other information. By comprehensively analyzing these data, we can comprehensively and scientifically evaluate the risk characteristics of the national land and transportation spatial planning and provide scientific support for planning decisions. By obtaining the risk characteristic value of the national land and transportation spatial planning, we can formulate targeted transportation planning risk management measures. Based on the in-depth analysis of transportation planning risks, we can provide a scientific basis for transportation planning and decision-making, and effectively respond to various risk challenges in transportation planning.

[0043] The formula for obtaining the risk characteristic value of land and transportation space planning is: ; In the formula, is the risk characteristic value of land and transportation space planning, FH is the traffic network load flow of land and transportation space planning, TC is the total length of railway facilities in land and transportation space planning, RX is the daily flow limit of urban roads in land and transportation space planning, FH0 is the traffic network load flow defined by land and transportation space stored in the database, TC0 is the total length of railway facilities in reference to land and transportation space stored in the database, RX0 is the daily flow limit of urban roads defined by land and transportation space stored in the database, is the compensation factor of the set FH, is the compensation factor of the set TC, It is the compensation factor of the set RX.

[0044] Calculating risk characteristic values ​​can evaluate and manage the risk status of the transportation system, which helps to identify possible traffic risks, including congestion, safety hazards and other problems, so as to take corresponding measures to reduce the possibility of risk occurrence; based on the calculation results of risk characteristic values, it can provide decision support for national land transportation space planning, help planners better understand the operation status and potential problems of the transportation system, optimize the planning and layout of transportation infrastructure, and improve the operation efficiency and safety of the transportation system; analyzing risk characteristic values ​​can better guide the rational allocation of resources. According to the risk assessment results, the resource allocation of the transportation system can be optimized, including road construction, transportation facility improvement and other aspects, so as to improve the overall operation efficiency and sustainability of the transportation system; The analysis based on risk characteristic values ​​can provide a basis for the formulation of emergency plans, understand possible risks and problems, formulate corresponding emergency response measures, and improve the ability and efficiency of responding to emergencies. The load flow of the transportation network, the total length of railway facilities, and the daily flow limit of urban roads in the national land transportation space planning are obtained through data collection, investigation and analysis by transportation planning departments, urban planning departments, transportation departments and other institutions. Traffic surveys, traffic model analysis, traffic demand forecasting and other methods can be used to obtain these data; The national land transportation space defines the traffic network load flow, the total length of railway facilities, and the daily flow limit of urban roads, which are stored in the traffic planning database, the urban planning database, the transportation statistics database, etc. These data need to be obtained through database query and data extraction; the compensation factors for the traffic network load flow, the total length of railway facilities, and the daily flow limit of urban roads in the national land transportation space planning are set, and the preset compensation factors are obtained from the database. The compensation factors need to be evaluated by traffic planning experts, analyzed by traffic demand forecasting models, and formulated by traffic planning policies. It is usually necessary to comprehensively consider the operating characteristics of the transportation system, future development trends and other factors to determine the appropriate compensation factors.

[0045] The national land space planning adjustment module is used to conduct risk assessment on the national land space planning based on the spatial risk characteristic values ​​of the national land ecological planning, the spatial risk characteristic values ​​of the national land energy planning, and the risk characteristic values ​​of the national land transportation space planning, and adjust the national land space planning according to the results of the national land space planning risk assessment.

[0046] The specific analysis process is as follows: based on the spatial risk characteristic values ​​of national ecological planning, the spatial risk characteristic values ​​of national energy planning and the risk characteristic values ​​of national transportation planning, a comprehensive analysis is performed to obtain the risk assessment value of national space planning, which is used as the analysis basis for risk assessment of national space planning; Compare the national land space planning risk assessment value with the national land space planning risk reference assessment value stored in the database; If the national land space planning risk assessment value is higher than or equal to the national land space planning risk reference assessment value, then there is no risk in the national land space planning; If the national land space planning risk assessment value is lower than the national land space planning risk reference assessment value, there is a risk in the national land space planning and it needs to be adjusted. The difference between the national land space planning risk reference assessment value and the national land space planning risk assessment value is obtained, and the difference between the national land space planning risk reference assessment value and the national land space planning risk assessment value is recorded as the national land space planning risk assessment deviation value. The national land space planning risk assessment deviation value is compared with the national land space planning adjustment plans corresponding to the national land space planning risk assessment deviation values ​​stored in the database to obtain the national land space planning adjustment plan corresponding to the national land space planning risk assessment deviation value. Based on the compared national land space planning adjustment plan, the national land space planning is adjusted.

[0047] By formulating and implementing adjustment plans based on risk assessment deviation values, we can more effectively control potential risks, improve the stability and reliability of the plan, and adjust the plan in a timely manner to make it more in line with current and future development needs, enhance the adaptability and flexibility of the plan. Adjusting the plan can optimize resource allocation, improve the efficiency of plan execution, avoid waste of resources and problems in the implementation of the plan. Through the adjustment of the plan, we can better promote the sustainable development of the national space, protect the ecological environment, and improve the efficiency of resource utilization. Adjusting the plan can make the plan more practical and more in line with the actual situation, and improve the effectiveness and success rate of plan implementation.

[0048] By conducting a risk assessment on the national land space planning and adjusting the national land space planning according to the results of the risk assessment, we can make planning adjustment decisions based on scientific data and analysis results, improve the scientificity and accuracy of planning decisions, and make the adjusted planning more targeted and better adapted to development needs under different risk scenarios. After conducting a risk assessment on the national land space planning, adjustments can be made based on the assessment results to increase the flexibility and adaptability of the planning. By adjusting the planning in a timely manner, we can better cope with changes and uncertainties in the external environment, making the planning more capable of responding to challenges. It can also help avoid waste of investment and resources, and improve the efficiency of planning implementation and social and economic benefits.

[0049] Risk Assessment Value of National Land Space Planning The calculation formula is: ; Comprehensive consideration of the risk characteristic values ​​of ecology, energy and transportation can realize the assessment of the comprehensive risk of national land space planning, which is helpful to fully understand the risks and challenges in ecology, energy and transportation that may be faced in the development process of national land space planning, and provide basic data support for scientific decision-making; integrating and calculating the risk characteristic values ​​of the three aspects can promote cross-departmental coordination and cooperation. Ecological, energy and transportation planning often involve multiple departments and stakeholders. Comprehensive assessment of national land space risks can promote information sharing and resource coordination among departments, which is conducive to forming comprehensive planning decisions; combining the risk characteristic values ​​of ecology, energy and transportation can provide important reference information for the formulation of comprehensive planning, promote the coordinated development of various national land space plans, and based on the analysis of comprehensive risk assessment values, it can guide the risk regulation and prevention work of national land space. Through the assessment of the overall risk, corresponding risk management strategies can be formulated to improve the sustainability and safety of national land space planning.
