Description

Technical Field

[0001] The present application relates to the technical field of water resource management, and in particular to a method, device, equipment and medium for determining the coordinated development level of an urban water system. Background Art

[0002] The urban water system is the product of the integrated development of social, economic and environmental factors, and is composed of multiple water-related subsystems that are interconnected and influence each other. In order to achieve resilient management of urban water systems and promote sustainable urban development, it is necessary to clarify the internal relationships and interaction mechanisms among the various water-related subsystems.

[0003] In the existing technology, the level of coordinated development among multiple systems in the environmental and economic fields is evaluated through coupling coordination models, but less attention is paid to the coupling relationship among water-related systems. At the same time, the coupling degree C obtained by applying the traditional coupling coordination model in the existing technology is not evenly distributed between [0,1], and the distinction between C values ​​at different time nodes is low, which greatly reduces the validity of the model.

[0004] Based on this, conducting a quantitative evaluation of the coordinated development level of urban water systems and improving the validity of the coupling coordination model are issues that need to be urgently addressed in the present invention. Summary of the invention

[0084] In this embodiment, based on historical data, a city water-related index database is determined, including:

[0085] Based on multiple city subsystems, after classifying and arranging historical data, information is extracted to obtain the first indicator corresponding to each city subsystem;

[0086] Based on the existing indicators in the historical data, the first indicators corresponding to each city subsystem are merged and screened to obtain the second indicators corresponding to each city subsystem;

[0087] Based on the second indicators corresponding to each urban subsystem, the third indicators corresponding to each urban subsystem are obtained by screening through expert consultation method or frequency statistics method;

[0088] Based on the preset characteristic data of the city to be evaluated, the third indicator corresponding to each city subsystem is adjusted to obtain the target indicator corresponding to each city subsystem, wherein the preset characteristic data of the city to be evaluated includes the meaning of the indicator representation, the characteristics of the city to be evaluated and the availability of data;

[0089] Based on the target indicators corresponding to each urban subsystem, a corresponding urban water-related indicator database is generated.

[0113] Linear interpolation is used to fill missing values ​​in the indicator data and generate an indicator data set;

[0114] Based on the indicator attributes, the indicators in the indicator data set are standardized to eliminate the influence of the indicator dimension and numerical range, so as to enhance the comparability of the indicator data.

[0115] The standardization of indicators in the indicator data set includes:

[0116] If the indicator attribute in the indicator data set is a positive effect, the indicator in the indicator data set is standardized as shown in the following formula:

[0117]

[0118] If the indicator attribute in the indicator data set is a negative effect, the indicator in the indicator data set is standardized as shown in the following formula:

[0120] In the formula, i is the indicator identifier, t is the time identifier, and X it is the value of index i in year t after standardization, x it is the value of indicator i in year t, x imax is the maximum value of index i in all years, x imin is the minimum value of index i in all years.

[0121] S402: Use entropy weight method or hierarchical analysis method to determine the weight of each evaluation index.

[0122] In this embodiment, for example, the information entropy of each evaluation index is calculated by the entropy weight method to determine the importance of each evaluation index, and the weight is assigned according to the size of the information entropy of each evaluation index, wherein the weight of each evaluation index is as follows: Figure 5 shown.

[0123] S403. Determine the comprehensive scores of the subsystems of the city to be evaluated corresponding to each urban subsystem over the years based on the weights of the evaluation indicators and the time series data.

[0124] In this embodiment, according to the weight of each evaluation index and the time series data, a weighted average calculation method is adopted to obtain the subsystem comprehensive scores of each urban subsystem corresponding to the city to be evaluated over the years, wherein the calculation formula of the subsystem comprehensive scores of each urban subsystem corresponding to the city to be evaluated over the years is as follows:

[0125]

[0126] In the formula, s is the urban subsystem identifier, t is the time identifier, i is the indicator identifier, and F st is the comprehensive score of city subsystem s in year t, α i is the weight of index i, X it is the value of indicator i in the tth year after standardization, and n is the number of indicators corresponding to the urban subsystem.

[0129] S601. For any two city subsystems, an absolute gap value is determined by the difference between the subsystem comprehensive scores of the two city subsystems over the years, and a relative gap value is determined by the ratio of the subsystem comprehensive scores of the two city subsystems over the years.

[0130] In this embodiment, the calculation formulas for the absolute gap value and the relative gap value of two city subsystems are as follows:

[0131] M ab =max(F a ,F b )

[0132] N ab =min(F a ,F b )

[0142] S701. Calculate the development degree of the urban water system based on the comprehensive scores of each urban subsystem over the years, wherein the development degree is used to evaluate the development level of the urban water system of the city to be evaluated.

[0143] In this embodiment, for example, the comprehensive scores of the city subsystems of the first city to be evaluated within a certain year are as follows: Figure 8 shown.

[0144] Depend on Figure 8 It can be seen that since 2010, the comprehensive scores of water security, water environment, water resources and water culture systems have shown an upward trend. Among them, the comprehensive scores of water security, water environment and water resources subsystems have steadily increased year by year, and the comprehensive score of water culture system has jumped since 2016. The comprehensive score of water ecosystem has shown a trend of first decreasing and then increasing.

[0145] By comparing the comprehensive scores of each urban subsystem based on time, the development level of the urban water system of the city to be evaluated can be accurately assessed.

[0146] S702. Calculate the coupling coordination degree between every two urban subsystems according to the first coupling degree, the second coupling degree and the third coupling degree between every two urban subsystems, wherein the coupling coordination degree is used to evaluate the coordination degree of the urban water system of the city to be evaluated.

[0147] In this embodiment, the calculation formula of the coupling coordination degree between two city subsystems is as follows:

[0148]

[0149] Where s is the urban subsystem identifier; n is the number of urban subsystems; α s is the undetermined coefficient of the urban subsystem s, α s The number of urban subsystems is evenly distributed, and the undetermined coefficient α of all urban subsystems s The sum is 1. In this embodiment, α s is 0.5; F s is the comprehensive score of the urban subsystem s; T is the coordination degree between urban subsystems; C is the coupling degree between urban subsystems. In this embodiment, C includes C0 ab 、C1 ab 、C2 ab; D is the coupling coordination degree between urban subsystems.

[0150] In this embodiment, the value range of the coupling coordination degree D between urban subsystems is 0 to 1. If the value of the coupling coordination degree D between urban subsystems is larger, it indicates that the coupling coordination level between urban subsystems is higher.

[0151] S703. Determine the category of the urban water system development level of the city to be evaluated based on the development level of the urban water system of the city to be evaluated and the coordination level of the urban water system of the city to be evaluated.

[0152] Optionally, the degree of coordinated development of the urban water system includes extremely disordered, seriously disordered, moderately disordered, slightly disordered, on the verge of disorder, marginally coordinated, primary coordinated, intermediate coordinated, well coordinated and high-quality coordinated.

[0153] In this embodiment, the classification criteria for the coordinated development degree of urban water systems are as follows: Fig. 9 shown.

[0154] Also optionally, the urban water system development level categories include unbalanced decline category, transitional development category and coordinated development category.

[0155] In this embodiment, the classification criteria for the urban water system development level of the city to be evaluated are determined according to the development level of the urban water system of the city to be evaluated and the coordination level of the urban water system of the city to be evaluated. Fig.10 shown.

[0156] The embodiment of the present application provides a method for determining the coordinated development level of a city water system. The development degree of the city water system is calculated by the comprehensive scores of the subsystems of each city subsystem over the years, so that the development trend of each city subsystem can be intuitively understood. The coupling coordination degree between each two city subsystems is calculated based on the first coupling degree, the second coupling degree, and the third coupling degree between each two city subsystems, and the development level category of the city water system of the city to be evaluated is determined based on the development degree of the city water system of the city to be evaluated and the coordination degree of the city water system of the city to be evaluated, thereby accurately determining the coordination degree and development level category of each city subsystem.

[0157] Optionally, for example, there are urban subsystems a and b. If the comprehensive score of urban subsystem a and the comprehensive score of urban subsystem b both vary in the range of 0 to 1, the coupling degree C values ​​of urban subsystem a and urban subsystem b are obtained in sequence by using the traditional algorithm, the modified algorithm 1 and the modified algorithm 2, respectively, wherein the coupling degree C value includes the first coupling degree, the second coupling degree and the third coupling degree. Then the function distribution of the coupling degree C value and the coupling coordination degree D value of urban subsystem a and urban subsystem b is as follows: Fig.11 shown.

[0158] Optionally, for example, there are urban subsystems a and b. If the comprehensive score of urban subsystem a is constant at 0.5, and the comprehensive score of urban subsystem b varies from 0 to 1, the coupling degree C values ​​of urban subsystems a and urban subsystems b are obtained in turn by the traditional algorithm, the modified algorithm 1, and the modified algorithm 2, respectively. The coupling degree C value includes the first coupling degree, the second coupling degree, and the third coupling degree. Then, the function distribution of the coupling degree C value and the coupling coordination degree D value of urban subsystems a and b is as follows: Fig.12 shown.

[0159] Depend on Fig.12 It can be seen that under the traditional algorithm, when the comprehensive score of urban subsystem b is greater than 0.5, the coupling degree C value converges quickly and the discrimination is too low.

[0160] In the modified algorithm 1, as the comprehensive score of urban subsystem b changes, the coupling degree C value is evenly distributed between [0, 1], and the differentiation is significantly improved. However, the coupling coordination degree D value shows an abnormality that D(0.5, 0.5) is greater than D(0.5, 0.6), that is, the influence of the coupling degree C value on the coupling coordination degree D value decreases, and the influence of the coordination degree T also decreases accordingly.

[0161] In the modified algorithm 2, the differentiation of the coupling degree C value is higher than that of the traditional algorithm, and it also balances the relative importance of the coupling degree C value and the coordination degree T in the calculation process of the coupling coordination degree D value.

[0162] Alternatively, based on the traditional algorithm, the modified algorithm 1 and the modified algorithm 2, the corresponding coupling degrees between the urban subsystems of the first city to be evaluated are obtained, and the coupling coordination degree D value between the urban subsystems of the first city to be evaluated is calculated as follows: Fig.13 As shown in the figure, under the traditional algorithm, the differentiation of D values ​​in different years is not high, especially for water resources and water environment systems. Since 2010, the coupling coordination degree D value has exceeded 0.8, and the differentiation of coupling coordination levels between urban subsystems is small, and the evaluation effectiveness is low. In the revised algorithm 1 and revised algorithm 2, the coupling coordination degree of water ecology and water resources, water environment, water culture and water safety subsystems in 2022 is lower than 0.6, which is in the barely coordinated stage. In 2022, the coupling coordination degree of the two exceeds 0.9, reaching the high-quality coordination level. Based on this, in the revised algorithm 1 and revised algorithm 2, the differentiation of coupling coordination levels between urban subsystems is more obvious, and the evaluation effectiveness is higher.
