Description

Technical Field

[0001] The present invention belongs to the technical field of infrastructure evaluation, and in particular relates to a method and system for evaluating the suitability of spatial distribution of transportation infrastructure. Background Art

[0002] With the acceleration of urbanization, the planning and construction of transportation infrastructure, a crucial pillar of urban development, are receiving increasing attention. Transportation infrastructure encompasses not only physical structures such as roads, bridges, tunnels, and public transportation systems, but also software technologies such as traffic signal control and intelligent transportation systems. However, as transportation demand continues to grow, the spatial distribution of existing transportation infrastructure often struggles to meet these increasingly complex and diverse needs.

[0003] Currently, the spatial distribution of transportation infrastructure relies primarily on the experience and intuition of urban planners, lacking a scientific, systematic evaluation method to guide its rational layout. This often leads to problems such as uneven resource allocation, traffic congestion, and low facility utilization during construction. Furthermore, as cities expand, the construction and maintenance costs of transportation infrastructure continue to rise. How to effectively utilize limited resources and achieve the optimal layout of transportation infrastructure is a key issue facing the current transportation planning field.

[0004] Existing technologies have the following problems when evaluating the spatial distribution suitability of transportation infrastructure: the evaluation method is single and lacks comprehensive consideration of multi-dimensional factors; it lacks dynamism and cannot adapt to the dynamic changes in transportation demand; it is highly subjective and the evaluation results are not objective and accurate enough; data utilization is insufficient and modern information technology is not fully utilized; it lacks systematicity and cannot form a complete evaluation system. Summary of the Invention

[0005] The purpose of the embodiments of the present invention is to provide a method and system for evaluating the suitability of spatial distribution of transportation infrastructure, aiming to solve the technical problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions.

[0007] In a first aspect, an embodiment of the present invention provides a method for evaluating the suitability of spatial distribution of transportation infrastructure, the evaluation method comprising the following steps:

[0008] Step S101: Evaluate the current habitat quality of the target area based on the Habitat Quality module in the InVEST model;

[0009] Step S102: Analyze the potential ecological losses of occupation, obstruction, and interference caused by the construction of transportation infrastructure in the target grid as the potential comprehensive ecological effects of transportation construction in the grid;

[0010] Step S103: Analyze the support role of resource conditions in the target area for transportation infrastructure, as well as the level of ecological environment recovery under natural conditions after being disturbed by transportation construction, and quantitatively evaluate the natural conditions for transportation construction in a grid-based manner;

[0011] Step S104: Using the grid as a unit and utilizing the 3D Magic Method, integrate the potential comprehensive ecological effects of transportation construction and the natural conditions of transportation construction, construct an assessment system for the carrying capacity of the ecosystem for transportation infrastructure, and conduct a quantitative assessment of the suitability of the spatial distribution of transportation infrastructure.

[0012] Furthermore, in step S101, the habitat quality assessment module based on the InVEST model conducts assessment with grids as units, and the formula is:

[0013]

[0014] In formula (1), H j is the habitat suitability of habitat type j; is the total threat level of habitat type j on grid x, k is the half-saturation constant, that is, half of the maximum degradation degree; z is the normalization constant, which is 2.5.

[0015] Furthermore, the overall threat level Based on habitat stress factors and ecological protection levels, the total threat level of each habitat type in each grid is analyzed. The value is [0,1]. The larger the value, the more susceptible the habitat type is to threats and thus to degradation.

[0016] Furthermore, in step S102, the comprehensive ecological effect of potential transportation construction is expressed as:

[0017] E = f(Q, S, D) (2);

[0018] In formula (2), E is the comprehensive ecological effect of potential transportation construction in the grid, Q is the loss of ecosystem occupied by potential transportation construction, S is the loss of ecosystem blocked by potential transportation construction, and D is the ecological loss of the system disturbed by potential transportation construction.

[0019] Furthermore, the potential ecological loss D of the transportation construction interference system is expressed as:

[0020]

[0021] In formula (3), d i represents the potential transportation construction-induced land use type conversion loss of the grid at distance i, x i Represents the probability of land use type conversion.

[0022] Furthermore, in step S104, the specific steps of using the 3D Magic method to evaluate the carrying capacity of the ecosystem for transportation infrastructure include: data collection and processing, construction of a multi-dimensional input matrix, weight allocation, and comprehensive evaluation;

[0023] In the data collection and processing steps, data related to transportation infrastructure construction and ecosystems are collected, including habitat quality, ecological stress factors, ecological protection level, resource support capacity, and natural resilience; and the data are pre-processed for normalization and standardization;

[0024] In the step of constructing a multidimensional input matrix, the preprocessed data is constructed into a multidimensional matrix, where each dimension represents an evaluation factor and each element in the matrix corresponds to the evaluation value of a grid cell. For example, habitat quality can be used as a dimension, and its value may be obtained based on the habitat quality assessment module of the InVEST model; ecological stress factor can be another dimension, and its value is obtained based on the assessment of the potential impact of transportation infrastructure on the ecosystem.

[0025] In the weight allocation step, the weight of each dimension is determined. The weight allocation should be based on the importance of the factor, expert opinions, historical data or policy orientation. Weight allocation can be achieved through various methods, such as the Analytic Hierarchy Process (AHP), the Delphi method or statistical analysis based on data.

[0026] In the comprehensive evaluation step, the algorithm of the three-dimensional magic method is used to convert the multi-dimensional input matrix into a single-dimensional output result.

[0027] In a second aspect, another embodiment of the present invention provides a transportation infrastructure spatial distribution suitability evaluation system, the evaluation system comprising:

[0028] The first analysis module is used to evaluate the current habitat quality of the target area based on the Habitat Quality module in the InVEST model;

[0029] The second analysis module is used to analyze the comprehensive ecological losses of occupation, obstruction, and interference that may be caused by the construction of transportation infrastructure in the grid of the target area, as the potential comprehensive ecological effects of transportation construction in the grid;

[0030] The third analysis module is used to analyze the support role of resource conditions in the target area for transportation infrastructure, as well as the level of ecological environment recovery under natural conditions after being disturbed by transportation construction, and to quantitatively evaluate the natural conditions for transportation construction in a grid-based manner;

[0031] The comprehensive evaluation module is used to integrate the potential comprehensive ecological effects and natural conditions of transportation construction using the grid as a unit and the three-dimensional magic method, to build an assessment system for the carrying capacity of the ecosystem for transportation infrastructure and to conduct a quantitative assessment of the suitability of the spatial distribution of transportation infrastructure.

[0032] In the third aspect, another embodiment of the present invention further provides a computer device, including a memory and a processor, wherein the memory stores a computer program executable by the processor, and when the processor executes the computer program, it implements the method for evaluating the suitability of the spatial distribution of transportation infrastructure provided in the first aspect.

[0033] In a fourth aspect, another embodiment of the present invention further provides a storage medium having a computer program stored thereon. When the computer program is read and executed, the method for evaluating the suitability of the spatial distribution of transportation infrastructure provided in the first aspect above is implemented.

[0034] Compared to existing technologies, the present invention's method and system for evaluating the spatial distribution suitability of transportation infrastructure offer the following benefits: Based on the theoretical approaches of ecological carrying capacity and ecosystem dynamics, and taking into account the comprehensive ecological effects of grid-based transportation construction and the natural conditions of transportation construction, this invention constructs an assessment system for the carrying capacity of ecosystems for transportation infrastructure. This system conducts spatial quantitative assessments, comprehensively evaluating the spatial distribution suitability of transportation infrastructure and improving resource utilization efficiency.

[0047] like Figure 1 As shown, in one embodiment of the present invention, a method for evaluating the suitability of spatial distribution of transportation infrastructure is provided.

[0048] Step S101: Evaluate the current habitat quality of the target area based on the Habitat Quality module in the InVEST model;

[0049] Step S102: Analyze the potential ecological losses of occupation, obstruction, and interference caused by the construction of transportation infrastructure in the target grid as the potential comprehensive ecological effects of transportation construction in the grid;

[0050] Step S103: Analyze the support role of resource conditions in the target area for transportation infrastructure, as well as the level of ecological environment recovery under natural conditions after being disturbed by transportation construction, and quantitatively evaluate the natural conditions for transportation construction in a grid-based manner;

[0051] Step S104: Using the grid as a unit and utilizing the 3D Magic Method, integrate the potential comprehensive ecological effects of transportation construction and the natural conditions of transportation construction, construct an assessment system for the carrying capacity of the ecosystem for transportation infrastructure, and conduct a quantitative assessment of the suitability of the spatial distribution of transportation infrastructure.

[0052] Furthermore, in step S101, the habitat quality assessment module based on the InVEST model conducts assessment with grids as units, and the formula is:

[0053]

[0054] In formula (1), H j is the habitat suitability of habitat type j; is the total threat level of habitat type j on grid x, k is the half-saturation constant, that is, half of the maximum degradation degree; z is the normalization constant, which is 2.5.

[0055] Calculation process:

[0056] a. Habitat suitability: Comprehensive analysis based on grid land use types and biological remote sensing monitoring indicators;

[0057] b. Ecological stress factors: Taking roads and railways as ecological stress factors, based on the parameters of traffic disturbance ecosystem effects in Part 1, analyze the relative sensitivity of each habitat type to each stress factor, as well as the distance attenuation effect of ecological stress;

[0058] c. Ecological protection level: Based on the analysis of various ecologically sensitive areas, ecological protection red lines, and basic farmland, the ecological protection level can be divided into four levels, as shown in the following table:

[0059]

[0060] d. Overall threat level: The overall threat level stated Based on habitat stress factors and ecological protection levels, the total threat level of each habitat type in each grid is analyzed. The value is [0,1]. The larger the value, the more susceptible the habitat type is to threats and thus to degradation.

[0061] Furthermore, six threat factors were selected, namely farmland, urban land, rural land, industrial and mining land, railways and roads. Parameters were calibrated based on the above research results. At the same time, different ecological protection levels were set for the core area, buffer zone and experimental area of ​​the reserve to improve the accuracy of model assessment and conduct spatial mapping of habitat quality.

[0062] Furthermore, in step S102, the comprehensive ecological effect of potential transportation construction is expressed as:

[0063] E = f(Q, S, D) (2);

[0064] In formula (2), E is the comprehensive ecological effect of potential transportation construction in the grid, Q is the loss of ecosystem occupation caused by potential transportation construction (i.e., the quality of the grid habitat), S is the loss of ecosystem barrier caused by potential transportation construction (i.e., the importance of the grid in the regional ecological pattern), and D is the ecological loss of the potential transportation construction interference system (i.e., the loss of habitat quality caused by inducing land use changes in surrounding grids).

[0065] Furthermore, the potential ecological loss D of the transportation construction interference system is expressed as:

[0066]

[0067] In formula (3), d i represents the potential transportation construction-induced land use type conversion loss of the grid at distance i, x i Represents the probability of land use type conversion.

[0068] Furthermore, the main evaluation indicators of natural conditions for transportation infrastructure construction are as follows:

[0069] field index Resource support Elevation, slope, undulation, etc. Natural resilience Temperature, humidity, light, soil and water conservation, etc.

[0070] Further, such as Figure 2 As shown, in step S104, the specific steps of using the three-dimensional magic method to evaluate the carrying capacity of the ecosystem for transportation infrastructure include: step S1041: data collection and processing; step S1042: constructing a multi-dimensional input matrix; step S1043: weight allocation; step S1044: comprehensive evaluation.

[0071] In the data collection and processing steps, data related to transportation infrastructure construction and ecosystems are collected, including habitat quality, ecological stress factors, ecological protection level, resource support capacity, and natural resilience; and the data are pre-processed for normalization and standardization;

[0072] In the step of constructing a multidimensional input matrix, the preprocessed data is constructed into a multidimensional matrix, where each dimension represents an evaluation factor and each element in the matrix corresponds to the evaluation value of a grid cell. For example, habitat quality can be used as a dimension, and its value may be obtained based on the habitat quality assessment module of the InVEST model; ecological stress factor can be another dimension, and its value is obtained based on the assessment of the potential impact of transportation infrastructure on the ecosystem.

[0073] In the weight allocation step, the weight of each dimension is determined. The weight allocation should be based on the importance of the factor, expert opinions, historical data or policy orientation. Weight allocation can be achieved through various methods, such as the Analytic Hierarchy Process (AHP), the Delphi method or statistical analysis based on data.

[0074] In the comprehensive evaluation step, the algorithm of the three-dimensional magic method is used to convert the multi-dimensional input matrix into a single-dimensional output result.

[0075] Based on the theoretical methods of ecological carrying capacity and ecosystem dynamics, this paper constructs an assessment system for the carrying capacity of ecosystems for transportation infrastructure, based on the comprehensive ecological effects of potential transportation construction in a grid and the natural conditions of transportation construction. This system conducts a spatialized quantitative assessment, which can comprehensively evaluate the spatial distribution suitability of transportation infrastructure and improve resource utilization efficiency. In summary, this paper provides a scientific and systematic method for assessing the carrying capacity of ecosystems for transportation infrastructure, contributing to the sustainable development of transportation infrastructure and the protection of the ecological environment.
