It should be understood that the drawings in the following introduction are only for conveniently and clearly expressing some embodiments of the technical solutions in the present application. For those skilled in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0059] The following details the embodiments of the present application. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application, and should not be construed as a limitation to the present application. For the step numbers in the following embodiments, they are only set for the convenience of explanation and illustration, and no limitation is imposed on the order between the steps. The execution order of each step in the embodiments can be adaptively adjusted according to the understanding of those skilled in the art.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.

[0061] Currently, the existing river health assessment technologies mainly construct an assessment index system from the perspectives of natural sciences such as the structure and function of the ecosystem and the services provided for society, and evaluate the river health based on the constructed assessment index system. However, since this method lacks evaluation index attributes for the river-society interaction and ignores these ethical factors, the evaluation results cannot comprehensively and accurately reflect the true health status of the river, which is extremely unfavorable for promoting river ecological protection and high-quality development.

[0062] Specifically, as a natural system with rich life characteristics, rivers also carry profound cultural heritage, long historical memory and important economic value. There are intricate and complex ethical connections between rivers and human society. From the perspective of natural science and providing services to society, the interaction factors between rivers and society are often ignored, such as the ethical connection between hydropower development and ecological protection, urban land and river flood channels. The evaluation results obtained without considering river ethical factors cannot fully and accurately reflect the true health status of the river. The objectivity and reliability of river health evaluation are low, and the accuracy of river health evaluation results is not high.

[0063] In addition, the existing evaluation index system is often constructed based on the simple relationship between each evaluation index. The evaluation index system obtained in this way can only reflect the simple and local information between the evaluation indicators, and cannot reflect the deep correlation information between the evaluation indicators. For example, it cannot reflect the effect of multiple evaluation indicators on river health, so that the subsequent evaluation results cannot comprehensively and accurately reflect the true health status of the river. The objectivity and reliability of river health evaluation are low, and the accuracy of river health evaluation results is not high.

[0064] In view of this, an embodiment of the present invention provides a river health assessment method, system, device and medium, wherein the method performs table weight analysis processing on a natural evaluation table and an ethical evaluation table, specifically by mining the correlation information between a natural attribute composed of a number of natural indicators and an ethical attribute composed of a number of ethical indicators from a global perspective, and extracting the correlation information between each natural indicator of the natural attribute and the relationship information between each ethical indicator of the ethical attribute from a local perspective, and then determining a natural weight set and an ethical weight set based on the correlation information mined from multiple angles, so that the natural weight set and the ethical weight set fully consider the deep correlation information of the evaluation indicators at local and global perspectives, which is conducive to improving the objectivity and reliability of subsequent river health assessments, and improving the accuracy of river health assessment results.

[0065] In addition, this method assigns scores and evaluates river data through natural evaluation tables, ethical evaluation tables, natural weight sets and ethical weight sets. It can not only evaluate the health of rivers from the perspective of natural science and service to society, but also monitor and evaluate rivers from the perspective of the ethical relationship between rivers and society. This is conducive to improving the comprehensiveness of river health evaluation, effectively improving the objectivity and reliability of river health evaluation, and improving the accuracy of river health evaluation results.

[0066] Reference Figure 1 In an embodiment of the present application, a river health assessment method includes:

[0067] Step 110: Obtain river data, a natural evaluation form, and an ethical evaluation form. The natural evaluation form records several natural indicators of the river, and the ethical evaluation form records several ethical indicators of the river.

[0068] In the embodiments of the present application, a river refers to a naturally formed water body, usually referring to a linear watercourse formed by the long-term accumulation of surface water or groundwater and flowing along a fixed path (river channel). The natural evaluation form is corresponding to the river and is constructed from the perspectives of natural sciences such as the ecosystem structure and function of the river and the services provided for society. This natural evaluation form is mainly constructed based on functions such as river structure, river water quality, river water volume, river biodiversity, and social services. Among them, the river structure function includes natural indicators such as the longitudinal connectivity index of the river, the natural condition of the shoreline, and the degree of illegal development and utilization of the water area shoreline; the river water quality function includes natural indicators such as the quality level of the water quality and the water self-purification ability; the river water volume function includes natural indicators such as the satisfaction degree of the ecological flow; the river biodiversity includes natural indicators such as the fish retention index and the coverage degree of aquatic plants; the social service function includes natural indicators such as the flood control compliance rate, the water supply volume guarantee rate, the shoreline utilization index, the watershed soil and water conservation rate, and the public satisfaction degree.

[0069] It can be understood that the ethical evaluation form is corresponding to the river and is constructed based on the complex ethical relationship between the river and society. This ethical evaluation form is mainly constructed based on ethical attributes and may include at least one ethical indicator such as the number of historical relics, the participation degree in cultural activities, the water resource development and utilization rate, the awareness of citizens to protect water, and the participation frequency of river protection actions. Among them, the number of historical relics and the participation degree in cultural activities are used to characterize the cultural value of the river's ethical attributes. The number of historical relics can be specifically determined by the total number of various relics with historical and cultural significance within the river basin; while the participation degree in cultural activities is used to characterize the attraction and inheritance vitality of the river's water culture to the population within the basin, and it can be specifically determined by the ratio of the number of participants in activities themed on the river's water culture to the total population within the basin. Ethical indicators such as the water resource development and utilization rate, the awareness of citizens to protect water, and the participation frequency of river protection actions are similar to the foregoing ethical indicators and can be simply analogized. Therefore, the present application will not elaborate on them here.

[0070] It should be noted that the river data can be data related to each natural indicator in the natural evaluation form and each ethical indicator represented by the ethical evaluation. There are already various specific data acquisition methods. For example, the required data can be obtained from the river based on each natural indicator or ethical indicator, and the river data can be determined by integrating the data corresponding to each indicator.

[0071] Step 120: Perform table weight analysis processing based on the natural evaluation table and the ethical evaluation table to obtain the natural weight set of the natural evaluation table and the ethical weight set of the ethical evaluation table; the natural weight set includes the natural attribute weight and the first weight corresponding to each natural indicator, and the ethical weight set includes the ethical attribute weight and the second weight corresponding to each ethical indicator;

[0072] In the embodiment of the present application, table weight analysis can be performed based on the natural evaluation table and the ethical evaluation table, so as to obtain the weight value of the natural attribute corresponding to all natural indicators of the natural evaluation table from a global perspective, denoted as the natural attribute weight, and the weight value of the ethical attribute corresponding to all ethical indicators of the ethical evaluation table, denoted as the ethical attribute weight; among them, the natural attribute weight value is used to characterize the importance of the natural attribute in the natural evaluation table and the ethical evaluation table, while the ethical attribute weight is used to characterize the importance of the ethical attribute in the natural evaluation table and the ethical evaluation table.

[0073] It can be understood that the table weight analysis of the natural evaluation table and the ethical evaluation table can also obtain the weight value corresponding to each natural indicator of the natural evaluation table from a local perspective, denoted as the first weight, and the weight value corresponding to each ethical indicator of the ethical evaluation table, denoted as the second weight; among them, each first weight is used to characterize the importance of the corresponding natural indicator among all natural indicators of the natural evaluation table, and each second weight is used to characterize the importance of the corresponding ethical indicator among all ethical indicators of the ethical evaluation table.

[0074] In some embodiments, the performing table weight analysis processing based on the natural evaluation table and the ethical evaluation table to obtain the natural weight set of the natural evaluation table and the ethical weight set of the ethical evaluation table includes:

[0075] Perform attribute weight analysis on the ethical evaluation table according to the natural evaluation table to obtain the natural attribute weight and the ethical attribute weight;

[0076] Further, the performing attribute weight analysis on the ethical evaluation table according to the natural evaluation table to obtain the natural attribute weight and the ethical attribute weight includes:

[0077] Obtain the natural attribute according to all natural indicators in the natural evaluation table, and obtain the ethical attribute according to all ethical indicators in the ethical evaluation table;

[0078] Construct an attribute judgment matrix according to the ethical attribute and the natural attribute;

[0079] In the embodiments of the present application, the table weight analysis process can first be to perform weight analysis on the attributes of the natural evaluation table and the ethical evaluation table from a global perspective, so as to obtain the natural attribute weight and the ethical attribute weight.

[0080] Specifically, first, all natural indicators in the natural evaluation table can be regarded as a whole, and this whole is determined as the natural attribute. The ethical attribute is the same as the aforementioned natural attribute; then, based on the analytic hierarchy process, a judgment matrix of the ethical attribute and the natural attribute is constructed, denoted as the attribute judgment matrix.

[0081] Perform attribute weight quantification analysis on the attribute judgment matrix to obtain the natural attribute weight and the ethical attribute weight.

[0082] Furthermore, the performing attribute weight quantification analysis on the attribute judgment matrix to obtain the natural attribute weight and the ethical attribute weight includes:

[0083] Perform scale quantification on the attribute judgment matrix to obtain an attribute quantification matrix. The attribute quantification matrix includes a number of attribute matrix elements, and each attribute matrix element is used to represent the relative importance degree between the corresponding two target attributes. The target attribute is the ethical attribute or the natural attribute;

[0084] Perform attribute weight calculation on the attribute quantification matrix to obtain the natural attribute weight and the ethical attribute weight.

[0085] In the embodiments of the present application, after obtaining the attribute judgment matrix between the natural attribute and the ethical attribute, the Saaty scale method can be used to quantitatively evaluate the relative importance degree of the two attributes in the attribute judgment matrix, so as to obtain an attribute quantification matrix. One matrix form of this attribute quantification matrix can be shown in Table 1 below:

[0086] Table 1

[0087]

[0088] It can be understood that the attribute quantification matrix in Table 1 includes 4 matrix elements, which are respectively the attribute matrix element of the natural attribute and the natural attribute, the attribute matrix element of the natural attribute and the ethical attribute, the attribute matrix element of the ethical attribute and the natural attribute, and the attribute matrix element of the ethical attribute and the ethical attribute; among them, the attribute matrix element 4 of the natural attribute and the ethical attribute is used to represent that the natural attribute is more important than the ethical attribute, and its importance degree is between the slightly important scale value 3 and the significantly important scale value 5 among all Saaty scale values. The same applies to the other attribute matrix elements, and they can be simply deduced by analogy.

[0089] It should be noted that after obtaining the attribute quantization matrix, based on the attribute quantization matrix, the importance degrees of natural attributes in the natural evaluation form and the ethical evaluation form (i.e., natural attribute weights), and the importance degrees of ethical attributes in the natural evaluation form and the ethical evaluation form (i.e., ethical attribute weights) can be determined from the attribute matrix elements representing the relative importance degrees.

[0090] Perform a natural index weight analysis on the natural evaluation form to obtain a number of the first weights, where each of the first weights is the importance degree of the corresponding natural index in the natural evaluation form;

[0091] Further, the performing a natural index weight analysis on the natural evaluation form to obtain a number of the first weights includes:

[0092] Construct a natural judgment matrix according to all the natural indexes in the natural evaluation form;

[0093] Perform a natural weight quantization analysis on the natural judgment matrix to obtain a number of the first weights.

[0094] Further, the performing a natural weight quantization analysis on the natural judgment matrix to obtain a number of the first weights includes:

[0095] Perform a scale quantization on the natural judgment matrix to obtain a natural quantization matrix, where the natural quantization matrix includes a number of natural matrix elements, and each natural matrix element is used to represent the relative importance degree between the corresponding two natural indexes;

[0096] In the embodiments of the present application, the weight analysis of each natural index in the natural evaluation form can be performed from a local perspective, so as to obtain the first weight corresponding to each natural index.

[0097] Specifically, first, a corresponding natural judgment matrix can be constructed based on all the natural indexes in the natural evaluation form, and a scale quantization is performed on the constructed natural judgment matrix, so as to obtain a natural quantization matrix corresponding to each index of the natural evaluation form. The content of specifically constructing the natural judgment matrix is similar to the content of the foregoing attribute judgment matrix, and the content of the natural quantization matrix is similar to the content of the foregoing attribute quantization matrix, and can be simply analogized. The difference is that the matrix rows or matrix columns of the attribute judgment matrix are constructed based on natural attributes or ethical attributes, while the matrix rows or columns of the natural judgment matrix are constructed based on each natural vegetation in the natural evaluation form, and the present application will not elaborate here.

[0098] Perform a natural weight calculation on the natural quantization matrix to obtain a number of the first weights.

[0099] Further, calculating natural weights for the natural quantization matrix to obtain a plurality of the first weights includes:

[0100] Performing matrix column normalization on the natural quantization matrix to obtain an intermediate matrix;

[0101] Performing matrix row summation processing on the intermediate matrix to obtain a row summation array, where the row summation array includes a plurality of row summation elements, and each row summation element corresponds to a matrix row of the intermediate matrix;

[0102] Extracting a plurality of the first weights from the row summation array.

[0103] In an embodiment of the present application, matrix column normalization may be to perform column normalization processing on each natural matrix element in the natural quantization matrix. For example, for a certain natural matrix element, the normalization value of this natural matrix element in its matrix column can be calculated, and the calculated normalization value can be determined as the new element value of this natural matrix element. The same applies to the remaining natural matrix elements, thereby obtaining the intermediate matrix. Exemplarily, if the matrix size of the natural quantization matrix is n×n, for the natural matrix element in the i-th matrix row and the j-th matrix column of the natural quantization matrix, its normalization value (i.e., the element value of the natural matrix element in the i-th matrix row and the j-th matrix column of the intermediate matrix) can be expressed as:

[0104]

[0105] Wherein, is the element value of the natural matrix element in the i-th matrix row and the j-th matrix column of the intermediate matrix; a ij is the element value of the natural matrix element in the i-th matrix row and the j-th matrix column of the natural quantization matrix; a kj is the element value of the natural matrix element in the k-th matrix row and the j-th matrix column of the natural quantization matrix; n is the maximum value of the matrix rows and columns of the natural quantization matrix.

[0106] It can be understood that after obtaining the intermediate matrix, based on the number of matrix rows, the natural matrix elements of the same matrix row in each intermediate matrix can be summed to obtain the sum of the element values of all natural matrix elements in each matrix row of the intermediate matrix, denoted as the row summation element. Then, based on the determined all row summation elements, a row summation array is constructed. Exemplarily, a certain row summation element can be expressed as:

[0107]

[0108] Wherein, M i is the i-th row summation element in the row summation array, that is, the sum of the element values of all natural matrix elements in the i-th matrix row of the intermediate matrix.

[0109] It should be noted that after obtaining the row sum array containing several row sum elements, the first weight corresponding to each natural index can be determined based on this row sum array. Specifically, in the first feasible implementation manner, each row sum element can be directly determined as the first weight of the corresponding natural index; or, in the second feasible implementation manner, first, the total value of all row sum elements in the row sum array can be obtained, and then based on the ratio between each row sum element and this total value, the first weight of each natural index is determined. The examples in this application are only for illustration and do not limit this application.

[0110] It is worth mentioning that the calculation of the attribute weights of the aforementioned attribute quantization matrix is similar to the calculation of the natural weights of the natural quantization matrix, and can be simply analogized and obtained. This application will not elaborate on this here.

[0111] Perform an ethical index weight analysis on the ethical evaluation form to obtain several of the second weights, and each of the second weights represents the importance degree of the corresponding ethical index in the ethical evaluation form.

[0112] Further, the step of performing an ethical index weight analysis on the ethical evaluation form to obtain several of the second weights includes:

[0113] Construct an ethical judgment matrix according to all the ethical indexes in the ethical evaluation form;

[0114] Perform an ethical weight quantization analysis on the ethical judgment matrix to obtain several of the second weights.

[0115] Further, the step of performing an ethical weight quantization analysis on the ethical judgment matrix to obtain several of the second weights includes:

[0116] Perform a scale quantization on the ethical judgment matrix to obtain an ethical quantization matrix, and the ethical quantization matrix includes several ethical matrix elements, and each ethical matrix element is used to represent the relative importance degree between the corresponding two ethical indexes;

[0117] Perform an ethical weight calculation on the ethical quantization matrix to obtain several of the second weights.

[0118] In the embodiments of this application, the content of performing an ethical index weight analysis on the ethical evaluation form is similar to the content of performing a natural index weight analysis on the aforementioned natural evaluation form, and can be simply analogized and obtained. This application will not elaborate on this here.

[0119] 130. According to the river data, perform a weight assignment evaluation on the natural evaluation form, the ethical evaluation form, the natural weight set, and the ethical weight set to obtain the health evaluation result of the river.

[0120] In the embodiments of the present application, the natural score and the ethical score of the river data can be obtained based on the natural evaluation form and the ethical evaluation form respectively, and then based on the natural attribute weights and all the first weights in the natural weight set, and the ethical attribute weights and all the second weights in the ethical weight set, the final health evaluation result of the river can be determined.

[0121] In some embodiments, the weight assignment evaluation of the natural evaluation form, the ethical evaluation form, the natural weight set and the ethical weight set is performed according to the river data to obtain the health evaluation result of the river, including:

[0122] According to the river data, a natural look-up table mapping is performed on the natural evaluation form to obtain several natural scores of the river, and each natural score corresponds to one natural index;

[0123] According to the river data, an ethical look-up table mapping is performed on the ethical evaluation form to obtain several ethical scores of the river, and each ethical score corresponds to one ethical index;

[0124] According to the natural weight set and the ethical weight set, a layer-by-layer weighted summation process is performed on all the natural scores and all the ethical scores to obtain the health evaluation result of the river.

[0125] In the embodiments of the present application, based on the part of the river data related to the natural index, a look-up table mapping can be performed on the natural evaluation form to obtain the score value of the river data under each natural index, which is recorded as the natural score; the ethical score is similar to the aforementioned natural score and can be simply analogized.

[0126] It can be understood that for all the natural scores, based on the natural attribute weights and all the first weights in the natural weight set, the total natural score of the river under the natural attribute can be determined; and based on the ethical attribute weights and all the second weights in the ethical weight set, the total ethical score of the river under the ethical attribute can be determined by a layer-by-layer weighting method; the sum of the determined total natural score and the total ethical score is obtained to obtain the health evaluation result of the river.

[0127] Exemplarily, for the total natural score or the total ethical score, it can be expressed as:
