Description

Technical Field

[0001] This invention relates to the field of water network construction technology, and in particular to a method, device and electronic equipment for evaluating the adaptability of water network construction. Background Technology

[0002] The national water network is a comprehensive system based on natural rivers and lakes, using water diversion and drainage projects as channels, water storage projects as nodes, and intelligent regulation as a means, integrating functions such as optimized allocation of water resources, flood control and disaster reduction in river basins, and protection of aquatic ecosystems. According to management authority and hierarchical management requirements, the national water network is divided into the national backbone network, provincial water networks, municipal water networks, and county-level water networks. With the rapid advancement of the construction of the main framework and major arteries of the national water network, provincial, municipal, and county-level water networks are also being planned intensively. Through major water source projects and important water diversion and drainage projects, interconnection and mutual assistance of water resources at all levels of the water network will be achieved, gradually forming a unified national water network, comprehensively improving my country's water security level from both macro-regional and administrative regional perspectives.

[0003] The national water network has diverse objectives and complex functions, with varying focuses in its construction at different levels. The national backbone network involves large investments, long construction periods, and wide-ranging impacts. It primarily leverages the advantages and comprehensive benefits of a super-large-scale water conservancy system to address the uneven spatial and temporal distribution of water resources and the accumulated ecological and environmental deficits, effectively responding to flood and drought risks, and achieving spatial balance, green development, and a higher standard of national security. Provincial water networks must connect with the national backbone network while coordinating the spatial balance of water conservancy development among cities and counties within the province. City and county-level water networks are mainly based on the provincial network, continuously optimizing and adjusting local water conservancy infrastructure construction. Therefore, the status and role of water networks at different levels differ, as do their impacts on economic and social development. Current technologies that use a uniform standard to measure the coordination between water network construction and the needs and pace of economic and social development cannot accurately reflect the differences between water networks at different levels and their impacts on economic and social development.

[0017] Currently, the national water network is divided into the national backbone network, provincial water networks, municipal water networks, and county-level water networks. The status and role of water networks at each level are different, and their impact on economic and social development is also different. The existing technology that uses a unified standard to measure whether the construction of water networks is in line with the needs and pace of economic and social development cannot reflect the differences between water networks at each level and the impact of water networks at each level on economic and social development in detail.

[0018] Based on this, the present invention provides a water network construction adaptability classification evaluation method, device and electronic equipment, which can alleviate the above-mentioned problems existing in related technologies.

[0019] To facilitate understanding of this embodiment, a detailed description of the water network construction adaptability grading evaluation method disclosed in this embodiment of the invention will be provided first. (See [link to relevant documentation]). Figure 1 As shown, the method may include the following steps:

[0020] Step S102: Obtain engineering information for water networks at all levels.

[0021] The aforementioned engineering information may include the type and details of each water network measure, as well as the number of measures for each type. The term "water network measure" can refer to water network engineering activities (i.e., water network engineering) and / or other construction activities related to the water network, and is not limited thereto. The measure information may include tasks, functions, and characteristic parameters, and is not limited thereto.

[0022] For example, the number of various water network projects (measures) can be statistically analyzed according to four levels: national backbone network, provincial water network, municipal water network, and county water network. The tasks, functions, and characteristic parameters of each water network project (measure) should be identified in detail. Various water network projects (measures) mainly include: flood control hub projects, flood (tide) dike projects, and flood (tide) drainage improvement projects related to the flood control and disaster reduction system; water source regulation and storage projects, water diversion projects, integrated urban and rural water supply projects, urban emergency backup water source projects, irrigation area projects, and centralized drinking water source protection projects related to the water resource allocation and water supply security system; ecological flow guarantee projects at important sections, soil and water conservation projects, ecological shoreline management projects, and fish protection and restoration projects related to the water ecological protection system; point source pollutant treatment projects, water body management projects, water ecological restoration and management projects, and river and lake shoreline renovation and upgrading projects related to the river and reservoir ecosystem protection and management system; waterfront environment improvement projects, water culture protection and inheritance measures, water-friendly and convenient facilities supporting projects, and water culture dissemination measures related to the water civilization construction system; and digital twin water network projects, water network intelligent scheduling and command platform construction projects, and water network full-element monitoring system construction projects related to the smart water network system.

[0023] The characteristic parameters of water network projects (measures) include, but are not limited to, the flood control or flood regulation capacity of flood control (tide) control projects, the designed water supply capacity of water resource allocation projects, the designed irrigation area of ​​irrigation district projects, the improvement and enhancement capacity of water ecological environment management projects, and the level of intelligent construction of water network projects.

[0024] Step S104: Based on the engineering information of water networks at all levels, establish a correspondence between the corresponding water network measures and at least one degree of adaptability for each level of water network.

[0025] Each fitness level may include at least one evaluation coefficient, and each evaluation coefficient may include at least one evaluation index; the above-mentioned at least one fitness level may include at least one of the following: a first fitness level representing security, a second fitness level representing livability, and a third fitness level representing civilization.

[0026] For example, at least one evaluation coefficient for the first suitability may include a flood control safety coefficient and a water supply safety coefficient; at least one evaluation coefficient for the second suitability may include an ecological protection coefficient and a livability and comfort coefficient; and at least one evaluation coefficient for the third suitability may include a humanistic coordination coefficient and a modern and advanced coefficient. Based on this, water network projects (measures) can be categorized and associated with the three suitability levels of safety, livability, and civilization according to their tasks and functions. An equal number of water network projects (measures) are selected for each evaluation indicator to facilitate subsequent analysis and calculation of the weights between the evaluation indicators. Table 1 shows the correspondence between the types of water network projects (measures) in the national water network construction and their suitability levels.

[0027] Table 1. Correspondence between the types of water network projects (measures) and their suitability in the national water network construction.

[0028]

[0029] The safety adaptability evaluation coefficient can be composed of two parts: flood control safety coefficient and water supply safety coefficient. The flood control safety coefficient can include four indicators: flood (tide) protection rate, flood (tide) compliance rate, post-flood (tide) disaster recovery rate, and effective flood storage rate. The water supply safety coefficient can include seven indicators: water network flow allocation rate, water supply safety population coverage rate, centralized water supply population coverage rate, urban emergency backup water source guarantee rate, effective irrigation area ratio, high-efficiency water-saving irrigation coverage rate, and centralized drinking water source quality compliance rate.

[0030] The flood (tide) protection rate reflects whether it benefits all regions and every person, and reflects the comprehensiveness of flood (tide) protection; the core of flood (tide) disaster prevention and control is flood (tide) disaster prevention and control measures, and the flood (tide) compliance rate reflects the comprehensive effect of flood (tide) engineering measures and non-engineering flood (tide) prevention measures; the post-flood (tide) disaster recovery rate is an important indicator of flood control resilience, and whether it can recover quickly after a flood (tide) disaster is an important indicator of the execution capacity of administrative management units in the areas involved in the water network; the effective flood storage rate reflects the ability of flood control structures to disperse, store, and delay floods, and reflects the degree of rational utilization of flood resources.

[0031] The water network allocation rate indicates the newly added water supply capacity from water network construction; the population coverage rate for safe water supply is the basic requirement for safe water supply; the population coverage rate for centralized water supply is the intermediate requirement for safe water supply; the urban emergency backup water source guarantee rate, on the basis of ensuring centralized water supply, further requires cities to have emergency water supply guarantee capabilities, which is a higher requirement for safe water supply; the effective irrigation area ratio reflects the basic level of irrigation; the coverage rate of high-efficiency water-saving irrigation reflects the level of high-efficiency water-saving irrigation, which is a higher requirement for irrigation development; the water quality compliance rate of centralized drinking water sources reflects the quality of water supply from the perspective of water quality.

[0032] The livability suitability evaluation coefficient can be composed of two parts: ecological protection coefficient and livability comfort coefficient. The ecological protection coefficient can include four indicators: the degree of ecological flow protection of important sections, soil erosion rate, ecological shoreline retention rate, and fish retention index. The livability comfort coefficient can include nine indicators: pollutant inflow rate, river runoff-to-pollution ratio, water quality compliance rate, excellent water body rate, proportion of water bodies that have lost their function, water body cleaning rate, public space rate of river and lake shorelines, suitability for recreation of river and lake shorelines, and effective management rate of river and lake shorelines.

[0033] Ecological flow assurance is an important foundation for river ecological restoration, mainly meeting the needs of the ecosystem for hydrological processes; a low soil erosion rate and a high ecological shoreline retention rate are the main manifestations of the health of the water network and aquatic ecological environment; the fish retention index is an important reflection of the ecological health of the river.

[0034] The pollutant discharge rate reflects the treatment level of point source pollutants; the river runoff-to-pollution ratio characterizes the water body's self-purification capacity in response to the amount of pollutants entering the river; the water quality compliance rate is a basic requirement for the livability of the water environment; the rate of excellent water bodies reflects a higher level of livability in terms of water quality; the higher the proportion of water bodies that have lost their function, the less suitable they are for living; the water body cleanliness rate is reflected in the sensory effects, and floating garbage in water bodies directly reduces the sensory appeal of the water body; the public space rate of river and lake shorelines is a basic condition for residents to freely approach and experience the water environment; the suitability of river and lake shorelines for recreation is a direct reflection of the livability of the water environment; and the effective management rate of river and lake shorelines is an important measure to maintain the sustainable livability of the water environment.

[0035] The civilization compatibility evaluation coefficient can be composed of two parts: the humanistic coordination coefficient and the modern advancement coefficient. The humanistic coordination coefficient can include four indicators: the level of waterfront environment creation, the level of water culture protection and inheritance, the level of supporting facilities for waterfront convenience, and the level of water culture dissemination. The modern advancement coefficient can include two indicators: the water network coverage rate and the intelligentization rate of water network projects.

[0036] The level of waterfront environment creation refers to the degree to which water culture is showcased, the experience and participation of visitors are enhanced, and the social and economic benefits are stimulated and improved while protecting the surrounding ecology. The level of water culture protection and inheritance refers to the strength of protection and inheritance of related water resources in the surrounding area, so as to reflect higher historical, scientific and economic value. Water-friendly and convenient facilities are an important part of the water culture landscape system, and the quality of their facilities directly affects the display effect of the landscape and the public's sensory experience of the landscape. The dissemination of water culture is the driving force for maintaining the enduring vitality of water culture. High-level dissemination helps to raise public awareness of water culture, cultivate and educate water culture professionals, and ensure the smooth progress of high-quality water conservancy projects.

[0037] The water network coverage rate represents the scope and area covered by the water network, reflecting the level of modernization in water network construction; the intelligentization rate of water network projects integrates the concept of digital twins, reflecting the degree of high-quality development of water conservancy in terms of measurement, monitoring, and management.

[0038] In practical applications, considering the different construction tasks and objectives of water networks at different levels, subjective evaluation can be the primary approach. The main evaluation indicators for different levels of water networks can be selected according to Table 2 to analyze the role of water networks at different levels more effectively and better reflect the degree of compatibility between the national water network and economic and social development.

[0040]

[0041] Step S106: Based on the correspondence between water network measures and adaptability at each level, determine the evaluation index information and weight information for each level of water network.

[0042] The evaluation index information mentioned above may include the value of each evaluation index, and the weight information mentioned above may include the first weight of each evaluation index and the second weight of each evaluation coefficient.

[0043] Step S108: Based on the evaluation index information and weight information of water networks at all levels, determine the suitability information of water networks at all levels.

[0044] The aforementioned fitness information may include the values ​​of each fitness level and a third weight.

[0045] Step S110: Based on the adaptability information of water networks at all levels, evaluate the adaptability of water network construction at all levels.

[0046] This invention provides a method for hierarchical evaluation of the adaptability of water network construction. First, it acquires engineering information for water networks at each level. Then, based on this information, it establishes a correspondence between corresponding water network measures and at least one degree of adaptability for each level of water network. Next, based on the correspondence between these measures and adaptability, it determines evaluation index information and weight information for each level of water network. Finally, based on these evaluation index and weight information, it determines the degree of adaptability for each level of water network. Finally, it evaluates the adaptability of water network construction at each level based on the degree of adaptability. This method, employing the above techniques, hierarchically evaluates the adaptability of water network construction to economic and social development from the perspectives of safety, livability, and civilization. This broadens the scope and depth of water network construction analysis and argumentation, thereby alleviating the problem that existing methods using uniform standards to measure the coordination between water network construction and the needs and pace of economic and social development cannot accurately reflect the differences between water networks at each level and their impact on economic and social development.

[0047] As one possible implementation, step S106 (i.e., determining the evaluation index information and weight information of each level of water network based on the correspondence between water network measures and adaptability) may include: determining the evaluation index information of each level of water network based on the correspondence between water network measures and adaptability; and determining the first weight of each evaluation index of each level of water network and the second weight of each evaluation coefficient of each level of water network.

[0048] For example, the correspondence between the aforementioned water network measures and their suitability can include: for each water network measure, there is an evaluation index corresponding to that water network measure in the corresponding evaluation coefficient of the corresponding suitability. Based on this, the step of determining the evaluation index information of each level of water network based on the correspondence between water network measures and suitability can include: for each level of water network, determining the set of water network measures corresponding to each evaluation index based on the correspondence between the measures and suitability of that level of water network, and determining the index values ​​of all water network measures in each set of water network measures for that level of water network, and then determining the values ​​of each evaluation index of that level of water network based on the evaluation values ​​of all water network measures in each set of water network measures for that level of water network.

[0049] For example, after obtaining all water network projects (measures) corresponding to each evaluation index for each level of water network, the arithmetic mean of the index values ​​of all water network projects (measures) corresponding to each evaluation index for each level of water network can be calculated as the value of that evaluation index for each level of water network.

[0143] As one possible implementation, the steps of determining the first weight of each evaluation index and the second weight of each evaluation coefficient of each level of water network may include:

[0144] Step 1: Obtain the index values ​​of all water network measures in the set of measures for each level of water network.

[0145] Step 2: Based on the index values ​​of all water network measures in the set of measures of each level of water network, the first weight of each evaluation index of each level of water network is determined by a preset objective weighting algorithm.

[0146] For example, the operation of step 2 above may include:

[0147] Step 21: Standardize the index values ​​of all water network measures in each water network measure set at each level of water network to obtain the standardized index values ​​of all water network measures in each water network measure set at each level of water network.

[0148] Step 22: Based on the standardized index values ​​of all water network measures in the set of measures for each level of water network, determine the average value and standard deviation of each evaluation index for each level of water network.

[0149] Step 23: Determine the independence coefficients of each evaluation index for each level of water network based on the average value and standard deviation of each evaluation index for each level of water network.

[0150] Step 24: Based on the independent coefficients of each evaluation indicator of each level of water network, determine the first weight of each evaluation indicator of each level of water network.

[0151] Step 3: Determine the second weight of each evaluation coefficient for each level of the water network.

[0152] As one possible implementation, step S108 (i.e., determining the suitability information of water networks at each level based on the evaluation index information and weight information of water networks at each level) may include:

[0153] (1) Based on the values ​​of each evaluation index and the first weight of each level of water network, determine the values ​​of each evaluation coefficient of each level of water network.

[0154] After obtaining the values ​​and weights of each evaluation index for each level of the water network, the weighted average method can be used to calculate the values ​​of each evaluation coefficient for each level of the water network. The calculation formula is as follows:

[0155]

[0156] In the formula: X lsp The calculated value (%) of the p-th evaluation coefficient for the s-th fit of the l-th water network, the same below; W lspi The weights of the s-th fit degree, p-th evaluation coefficient, and i-th evaluation index of the l-th water network are given below.

[0157] (2) Based on the values ​​of each evaluation coefficient and the second weight of each level of water network, determine the value of each fitness degree of each level of water network.

[0158] After obtaining the values ​​and weights of the evaluation coefficients for each level of the water network, the weighted average method can be used to calculate the values ​​of the fit of each level of the water network. The calculation formula is as follows:

[0159]

[0160] In the formula: X ls W is the calculated value (%) of the s-th fitness degree of the 1st-level water network; lsp The weight of the p-th evaluation coefficient for the s-th fit of the l-th water network.

[0161] (3) Determine the third weight of each level of water network adaptability.

[0162] For ease of understanding, the determination methods of the first weight, second weight, and third weight are described below as an example.

[0163] Weights are measures of the degree of variation of each attribute within an attribute set and its influence on other attributes. The original information for weighting should directly originate from the objective environment. The CRITIC method, a key objective weighting method, can be used first to determine the weights of each evaluation indicator for each level of the water network. Then, based on the different construction goals and tasks of each level of the water network, the weights of each evaluation coefficient and each suitability level of the water network can be determined sequentially.

[0164] The procedure for determining weights using the CRITIC method is as follows:

[0165] 1) Establish a data matrix.

[0166] After obtaining the index values ​​of each level of water network and each water network project (measure), a data matrix in the following form can be established:

[0167]

[0168] In the formula: X lspmn The value (%) of the nth water network project (measure) is the sth adaptation degree, pth evaluation coefficient, mth evaluation index, and nth adaptation degree of the l-th water network.

[0169] 2) Data standardization processing.

[0170] For indicators where larger is always better (positive indicators):

[0171]

[0172] For indicators where smaller is better (negative indicators):

[0173]

[0174] Where: minX lspij maxX lspij These represent the minimum and maximum values ​​of the following indicators for the s-th fit degree, p-th evaluation coefficient, ith evaluation index, and j-th water network project (measure) of the l-th level water network: X′ lspij These are the standardized evaluation index values.

[0175] 3) Calculate the standard deviation of the evaluation index.

[0176]

[0177] In the formula: S′ lspi X′ represents the standard deviation (after standardization) of the s-th fit, p-th evaluation coefficient, and i-th evaluation index of the l-th water network. lspiThis represents the average value (after standardization) of the s-th fit degree, p-th evaluation coefficient, and i-th evaluation index of the l-th water network.

[0178] 4) Calculate the independence coefficients of the evaluation indicators.

[0179]

[0180] In the formula: R lspi r is the independent coefficient of the s-th fitness degree, p-th evaluation coefficient, and i-th evaluation index of the l-th water network; lspk-i The correlation coefficient between the s-th fit of the l-th water network, the p-th evaluation coefficient, the k-th evaluation index, and the i-th evaluation index; and These represent the average values ​​(after standardization) of the s-th fit degree, p-th evaluation coefficient, k-th evaluation index, and i-th evaluation index of the l-th water network.

[0181] 5) Calculate the weights of the evaluation indicators.

[0182]

[0183] C lspi =S′ lspi ×R lspi , l=1,2,3,4, s=1,2,3, p=1,2, i=1,2,…,m

[0184] In the formula: C lspi The information content contained in the s-th fitness degree, p-th evaluation coefficient, and ith evaluation index of the l-th water network is represented by the product of the standard deviation and the independence coefficient of the evaluation index.

[0185] The weights of the evaluation coefficients and the suitability scores of water networks at different levels are mainly determined by the different tasks and functions of water network construction. The subjective evaluation of these weights also differs in emphasis: the national backbone network primarily considers macro-level security, while provincial, municipal, and county-level water networks have increasingly higher requirements for livability and civilization. Table 3 shows the weights of the evaluation coefficients for each level of water network, and Table 4 shows the weights of the suitability scores for each level of water network.

[0186] Table 3. Grading Weights of Evaluation Coefficients for National Water Network Construction

[0187]

[0188] Table 4. Grading Weights for Adaptability to National Water Network Construction

[0189]

[0190] As one possible implementation, step S110 (i.e., evaluating the adaptability of water network construction at each level based on the adaptability information of water networks at each level) may include:

[0191] Step A: Based on the fit values ​​of each level of water network and the third weight, determine the fit score of each level of water network.

[0192] After obtaining the values ​​and weights of the fitness of each level of the water network, the weighted average method can be used to calculate the fitness score of each level of the water network. The calculation formula is as follows:

[0193]

[0194] In the formula: F l The adaptability score for the L-level water network; X′ ls Assign a score to the s-th fitness degree of the l-th water network, by X. ls Scoring was obtained according to the scoring rules shown in Table 5; W ls The weight of the s-th fitness of the l-th water network.

[0195] Step B: Based on the adaptability scores of each level of water network and the pre-divided multiple score intervals, determine the level of each level of water network.

[0196] After obtaining the suitability scores for each level of the water network, the level of each level of the water network can be determined according to the level determination rules shown in Table 5. That is: when the suitability score of the water network is below 60 points, the suitability of the water network is poor; when the suitability score of the water network is not lower than 60 points but lower than 70 points, the suitability of the water network is acceptable; when the suitability score of the water network is not lower than 70 points but lower than 80 points, the suitability of the water network is average; when the suitability score of the water network is not lower than 80 points but lower than 90 points, the suitability of the water network is good; when the suitability score of the water network is not lower than 90 points but not higher than 100 points, the suitability of the water network is excellent.

[0197] Table 5. Evaluation Table of Adaptability Grading for National Water Network Construction

[0198]

[0199] For ease of understanding, the above-mentioned water network construction adaptability classification evaluation method is described as an example using a specific application as follows. See [link to documentation]. Figure 2 As shown, the above-mentioned water network construction adaptability classification evaluation method can be carried out according to the following operation method:

[0200] Step 1: According to the four levels of national backbone network, provincial water network, municipal water network and county water network, count the number of various water network projects (measures) at different levels, and focus on sorting out the tasks, functions and characteristic parameters of each water network project (measure).

[0201] Step two: Based on the tasks and functions of different types of water network projects (measures), match the water network projects (measures) with the three suitability levels of safety, livability, and civilization.

[0202] In this process, the same number of water network projects (measures) are selected for each evaluation indicator so that the weights between the evaluation indicators of each level of water network can be calculated in subsequent analysis.

[0203] Step 3: Based on the four levels of national backbone network, provincial water network, municipal water network, and county water network, select and calculate the main evaluation indicators corresponding to the evaluation coefficients of different adaptability of water networks at each level, and construct the evaluation coefficients for each of the three adaptability levels of safety, livability, and civilization.

[0204] The evaluation coefficients for safety adaptability include flood control safety coefficient and water supply safety coefficient; the evaluation coefficients for livability adaptability include ecological protection coefficient and livability comfort coefficient; and the evaluation coefficients for civilization adaptability include humanistic harmony coefficient and modern advancement coefficient. The main evaluation indicators corresponding to different adaptability levels of water networks at each level can be selected according to Table 2.

[0205] Step four: Quantitatively calculate and analyze the weights of each evaluation index, the weights of each evaluation coefficient, and the weights of each suitability of each water network at all levels.

[0206] The CRITIC method was used to calculate the weights of each evaluation index for each level of water network. Based on the different focuses of construction tasks and objectives, the weights of each evaluation coefficient and each suitability degree of each level of water network were analyzed and determined.

[0207] The national, provincial, municipal, and county-level water networks have different focuses in their construction. The national backbone network mainly addresses water resource allocation and flood control and disaster reduction at the southeast, northwest, and other regional levels. It is based on major rivers and important lakes, with major water diversion projects and flood storage projects as the backbone, and control reservoirs as allocation hubs. Through interconnection, multi-source complementarity, and combined storage and discharge, it constructs the main framework and artery of the national water network. Provincial, municipal, and county-level water networks mainly rely on the national backbone network and the water network at the next higher level. They focus on interconnection, network supplementation, and chain strengthening as the key points of water network construction, optimize the construction sequence, and form an integrated and interconnected water network system that focuses on solving water conservancy service guarantee issues such as flood control, water supply, irrigation, and water ecological environment protection within the administrative region, providing high-quality water conservancy public services, and building a modern and high-quality water conservancy infrastructure network. It is evident that the national backbone network construction places greater emphasis on security, while the provincial, municipal, and county-level water network construction has higher requirements for livability and civilization. The economic and social demands on water networks at all levels and the perspectives from which water networks at each level contribute to economic and social benefits differ, so the selected evaluation indicators and the weighting of the three suitability factors of security, livability, and civilization should also differ.

[0208] Step 5: Conduct a tiered evaluation of the suitability of the national water network construction.

[0209] The weighted average method was used to calculate the evaluation coefficients and adaptability of each level of water network in turn, and the adaptability scoring rules were formulated (as shown in Table 5) to assign adaptability scores to each level of water network. Based on the adaptability scores and their weights, the adaptability scores of each level of water network were calculated by weighted average, thereby judging the adaptability level of each level of water network with economic and social development (as shown in Table 5), and then comprehensively evaluating the adaptability of the national water network construction.

[0210] The suitability scores for each level of water network are based on a 100-point scale, with suitability levels categorized into five levels: poor, fair, average, good, and excellent. Relevant personnel can then propose key points for the construction of water networks at each level and identify issues requiring focused attention based on the comprehensive evaluation results.

[0211] Unlike existing national water network construction methods that focus on macro-level factors and use a single comparative approach, the aforementioned water network construction adaptability grading evaluation method starts from the perspectives of safety, livability, and civilization. It prioritizes safety and reliability, comfort and livability, and the long-term inheritance of culture as its core values. It adopts a combination of objective empowerment and subjective evaluation to quantify the adaptability of national water network construction to economic and social development, thus broadening the scope and depth of water network construction analysis and demonstration. It is highly targeted, instructive, and practical for the direction and planning of national water network construction.

[0212] Based on the above-mentioned method for evaluating the adaptability of water network construction, this invention also provides a device for evaluating the adaptability of water network construction. (See attached image.) Figure 3 As shown, the device may include the following modules:

[0213] The acquisition module 302 is used to acquire engineering information of water networks at all levels; wherein, the engineering information includes the type and information of each water network measure, as well as the number of water network measures of each type.

[0214] Module 304 is established to establish a correspondence between corresponding water network measures and at least one degree of fit for each level of water network based on engineering information of water networks at all levels; wherein each degree of fit includes at least one evaluation coefficient, and each evaluation coefficient includes at least one evaluation index; the at least one degree of fit includes at least one of the following: a first degree of fit representing safety, a second degree of fit representing livability, and a third degree of fit representing civilization.

[0215] The first determining module 306 is used to determine the evaluation index information and weight information of each level of water network based on the correspondence between water network measures and adaptability of each level of water network; wherein, the evaluation index information includes the value of each evaluation index, and the weight information includes the first weight of each evaluation index and the second weight of each evaluation coefficient.

[0216] The second determining module 308 is used to determine the adaptability information of each level of water network based on the evaluation index information and weight information of each level of water network; wherein, the adaptability information includes the value of each adaptability and a third weight.

[0217] Evaluation module 310 is used to evaluate the adaptability of water network construction at each level based on the adaptability information of water networks at each level.

[0218] By using the aforementioned water network construction adaptability grading evaluation device, the adaptability of water network construction to economic and social development can be evaluated from the perspectives of safety, livability, and civilization. This broadens the scope and depth of water network construction analysis and demonstration, thereby alleviating the problem that the existing technology, which uses a unified standard to measure whether water network construction is coordinated with the needs and pace of economic and social development, cannot accurately reflect the differences between water networks at different levels and the impact of water networks at different levels on economic and social development.

[0219] At least one evaluation coefficient for the first degree of fit may include a flood control safety coefficient and a water supply safety coefficient; at least one evaluation coefficient for the second degree of fit may include an ecological protection coefficient and a livability and comfort coefficient; at least one evaluation coefficient for the third degree of fit may include a humanistic coordination coefficient and a modern and advanced coefficient.

[0220] The aforementioned first determining module 306 can also be used to: determine the evaluation index information of each level of water network based on the correspondence between water network measures and adaptability; and determine the first weight of each evaluation index of each level of water network and the second weight of each evaluation coefficient of each level of water network.

[0221] The correspondence between water network measures and their suitability can include: for each water network measure, there is an evaluation index in the corresponding evaluation coefficient of the corresponding suitability that corresponds to that water network measure. Based on this, the first determining module 306 can also be used to: for each level of water network, determine the set of water network measures corresponding to each evaluation index for that level of water network based on the correspondence between the measures and suitability of that level of water network, and determine the index values ​​of all water network measures in each set of water network measures for that level of water network, and then determine the values ​​of each evaluation index for that level of water network based on the evaluation values ​​of all water network measures in each set of water network measures for that level of water network.

[0222] The aforementioned first determining module 306 can also be used to: obtain the index values ​​of all water network measures in the water network measure set of each level; based on the index values ​​of all water network measures in the water network measure set of each level, determine the first weight of each evaluation index of each level of water network using a preset objective weighting algorithm; and determine the second weight of each evaluation coefficient of each level of water network.

[0223] The aforementioned first determining module 306 can also be used to: standardize the index values ​​of all water network measures in each water network measure set of each level of water network to obtain standardized index values ​​of all water network measures in each water network measure set of each level of water network; determine the average value and standard deviation of each evaluation index of each level of water network based on the standardized index values ​​of all water network measures in each water network measure set of each level of water network; determine the independence coefficient of each evaluation index of each level of water network based on the average value and standard deviation of each evaluation index of each level of water network; and determine the first weight of each evaluation index of each level of water network based on the independence coefficient of each evaluation index of each level of water network.

[0224] The second determining module 308 mentioned above can also be used to: determine the value of each evaluation coefficient of each water network at each level based on the value of each evaluation index and the first weight; determine the value of each fitness level of each water network at each level based on the value of each evaluation coefficient and the second weight; and determine the third weight of each fitness level of each water network at each level.

[0225] The aforementioned evaluation module 310 can also be used to: determine the adaptability score of each level of water network based on the adaptability values ​​of each level of water network and the third weight; and determine the level of each level of water network based on the adaptability scores of each level of water network and multiple pre-divided score intervals.
