Primary and secondary water-related problems such as water resource shortage, water environment pollution and water ecological degradation are becoming increasingly prominent. Under the interaction of resource-based and pollution-based water shortages, the water ecological environment is deteriorating and the difficulty of restoration and management is increasing, which has become a difficult point in the protection of water ecological environment.

[0003] The current water ecological restoration still has the problems of large dispersion, high cost, and lack of suitable ecological restoration for polluted waters. The existing scientific decision-making method for the implementation plan of ecological restoration of polluted waters, and the lack of feedback mechanism during the implementation process, have resulted in the inability to accurately judge the starting point of the implementation of ecological restoration of polluted waters, the turning point of the implementation stage, the weak scientific basis for decision-making, and the unclear implementation effect.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Disturbed by strong human activities such as urbanization and industrialization, the water ecological process of urban water environment is undergoing profound changes. Primary and secondary water-related problems such as water resource shortage, water environment pollution and water ecological degradation are becoming increasingly prominent. Under the interaction of resource-based and pollution-based water shortages, the water ecological environment continues to deteriorate and the difficulty of restoration and management increases, becoming a difficult point in the protection of the water ecological environment. However, there is still a lack of implementation plans and paths for the ecological recovery of water bodies with different degrees of pollution under strong human activities.

[0030] The current water ecological restoration still has the problems of large dispersion, high cost, and lack of suitable ecological restoration for polluted waters. The existing implementation plan for ecological restoration of polluted waters has a scientific decision-making method, and there is a lack of feedback mechanism during the implementation process, which results in the inability to accurately judge the starting point of the implementation of ecological restoration of polluted waters, the turning point of the implementation stage, the weak scientific basis for decision-making, and the insignificant implementation effect. In the process of project implementation, the indicators concerned are different for different stages of ecological restoration. Failure to focus on indicators at different stages is likely to cause a waste of monitoring funds. The existing engineering guidelines for water governance are all one-way implementation measures, and the feedback mechanism cannot be set according to the actual situation. It is impossible to guarantee the implementation effect of each stage and adjust the plan in real time and scientifically, which also causes the unstable governance effect to occur repeatedly. On the other hand, the ecological restoration of watershed waters is a systematic problem. Considering that the ecological restoration of watershed waters is a systematic process that requires multi-party coupling and progression, in the implementation process of ecological restoration of polluted waters in watersheds with strong human activities, it should be combined with the actual situation of the basin, coupled with feedback indicators, and implemented progressively with phased goals, and the implementation plan should be flexibly adjusted according to the feedback indicators.

[0031] Based on this, the purpose of the present invention is to overcome the shortcomings of existing watershed water ecological restoration technology and provide a method for ecological restoration of polluted waters based on fuzzy multi-level analysis feedback theory. The method can realize real-time judgment and analysis based on fuzzy multi-level analysis feedback theory, combined with water section response data during implementation, to adjust the most suitable governance stage and governance measures for the current situation.

[0032] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] Embodiment 1

[0034] The present invention provides a method for evaluating aquatic ecological restoration scheme. Figure 1 The embodiment of the present invention shown in the figure provides a flow chart of a method for evaluating a water ecological restoration program, the method comprising:

[0035] Step S102, obtaining the ecological recovery target of the target water area and the implementation start phase of the protection of the target water area.

[0036] Specifically, this step includes collecting and analyzing relevant data of the target waters, understanding their current ecological and environmental conditions, and setting ecological restoration goals that are expected to be achieved through future protection plans. Furthermore, the overall goal can be divided into multiple phased goals, and different protection plans can be set for each phased goal; there are many ecological recovery goals, such as eliminating black and odorous water bodies, improving the quality of rivers / waters, and ecological restoration.

[0037] Step S104, determining a first scaling matrix of feedback indicators corresponding to the target waters based on the ecological recovery goal and the initial stage of implementation; wherein the feedback indicators include at least one of the following: physical and chemical indicators, nutrient indicators, unconventional indicators, hydraulic indicators and biological indicators.

[0038] Specifically, feedback indicators are important parameters for evaluating the effectiveness of water area protection, which may include physical and chemical indicators (such as pH value, dissolved oxygen, etc.), nutrient indicators (such as nitrogen, phosphorus, etc.), unconventional indicators (such as heavy metals, organic pollutants, etc.), hydraulic indicators (such as flow rate, flow, etc.) and biological indicators (such as biodiversity, population size, etc.).

[0039] For example, feedback indicators are obtained based on the indicator data of polluted water sections, and the sections include national, provincial or municipal control sections of the river basin, and can also be sub-basin water sections. Section feedback indicators include physical and chemical indicators, nutrient indicators, unconventional indicators, hydraulic indicators and biological indicators. Sub-feedback indicators can be adjusted according to actual conditions, or adjusted to other feedback indicators. Based on the indicators of polluted water section data, an evaluation system is constructed, as shown in Table 1.

[0040] Table 1 Feedback index evaluation system for polluted water sections

[0041]

[0042] Step S106, determining a second scaling matrix of the protection plan based on the target feedback index; wherein the protection plan includes at least one of the following: reducing pollution entering the river from the basin, regulating endogenous pollution in the river, ensuring the ecological base flow of the river, and reconstructing the ecological space of the basin.

[0043] Specifically, the protection plan is a specific measure taken to achieve the goal of ecological recovery, which may include reducing pollution entering the river, regulating endogenous pollution in the river, ensuring the ecological base flow of the river, and reconstructing the ecological space of the river basin. According to the 0.1-0.9 nine-scale quantitative scale shown in Table 2, feedback indicators and protection plans are analyzed pairwise to construct a scaling matrix, where the fuzzy complementary scaling matrix of the feedback indicators is shown in Table 3.

[0044] Table 2 0.1-0.9 scaling method

[0045]

[0046]

[0047] For example, the current waters are black and smelly, and the physical and chemical indicators are more important than the nutrient indicators, unconventional indicators, hydraulic indicators and biological indicators. Therefore, the scale of the physical and chemical indicators corresponding to the nutrient indicators can be 0.6, the scale of the unconventional indicators can be 0.7, the scale of the hydraulic indicators can be 0.8, and the scale of the biological indicators can be 0.9; the scale of the biological indicators corresponding to the physical and chemical indicators is 0.1, the scale of the hydraulic indicators corresponding to the physical and chemical indicators is 0.2, the scale of the unconventional indicators corresponding to the physical and chemical indicators is 0.3, and the scale of the nutrient indicators should be 0.4.

[0048] Similarly, it is necessary to improve the standards and quality of physical and chemical indicators. At this time, the physical and chemical indicators are the target feedback indicators. The plan to reduce pollution entering the river is more important than the plan to reconstruct the ecological space of the river. That is, the scale of the plan to reduce pollution entering the river relative to the plan to reconstruct the ecological space of the river can be 0.9.

[0049] Table 3 Scaling matrix of feedback indicators

[0050]

[0051]

[0052] Furthermore, if there are multiple scoring parties, the mode or the weighted average of the modes can be used as the scaling result.

[0053] Specifically, the mode is used as the comparison result for a certain party. For example, when multiple experts in ecological restoration give scores, the mode is used as the comparison result, which means that multiple experts have a consistent view. Alternatively, the scoring results of each party are weighted averaged based on the mode of each party. For example, if experts, functional personnel, and citizens give scores, the mode of each party is taken first, and then the mode of experts, functional personnel, and citizens is weighted averaged according to the importance.

[0054] Step S108, performing fuzzy consistency processing and normalization processing on multiple scale matrices in turn to obtain multiple weight vectors, and determining a comprehensive weight based on the multiple weight vectors; wherein the scale matrix includes a first scale matrix and a second scale matrix.

[0055] Specifically, the fuzzy consistency algorithm is a method for processing uncertain information and can be used to deal with fuzziness and uncertainty in the evaluation of protection schemes.

[0056] Furthermore, in some preferred embodiments of the present invention, the fuzzy consistency matrix is ​​determined based on the following formula: Among them, r ij is the element in the i-th row and j-th column of the fuzzy consistency matrix, r i is the sum of the elements in the i-th row of the scaling matrix, rj is the sum of the elements in the jth column of the scaling matrix, and n is the order of the fuzzy consistency matrix.

[0057] Specifically, normalization is the process of converting data into a uniform range or scale to facilitate comparison and analysis.

[0058] Furthermore, in some preferred embodiments of the present invention, the weight vector is determined based on the following formula: a=(n-1) / 2; where W i is the i-th element of the weight vector, n is the order of the fuzzy consistency matrix, r ik is the element in the i-th row and k-th column of the fuzzy consistency matrix.

[0059] For example, for the matrix B=b ij Sum of rows of (n×n) Table 3 shows the r corresponding to the feedback index. i .

[0060] pass The fuzzy consistency matrix R is obtained as follows: ij ), R is an n×n matrix, and the matrix R is normalized to obtain the factor sorting vector W = (W1, W2, ..., W n ) T , where the W vector satisfies Where n is the matrix order, a = (n-1) / 2, and ∑W i =1. Table 4 shows the first fuzzy consistency matrix and the first weight vector of the feedback indicators, and Table 5 shows the second fuzzy consistency matrix and the second weight vector of the protection scheme. The weight value shows that in the indicator layer of the feedback model, the numerical value of the weight of the physical and chemical indicators, nutrient salt indicators, unconventional indicators, hydraulic indicators and biological indicators reflects their importance in the stage of reducing pollution entering the river basin. The larger the weight, the more important the indicator is and the more urgent it is to be assessed.

[0061] Table 4 Fuzzy consistency matrix and weight vector of feedback indicators

[0062]

[0063] Specifically, the comprehensive weight is the weight obtained by considering the importance of feedback indicators and implementation plans, and can be used to evaluate the comprehensive effects of different protection plans.

[0064] Exemplarily, the product of the first weight and the second weight is used as the comprehensive weight, see Table 5, in which W B1 W is the first weight vector determined by B1 based on the ecological recovery goal and the initial stage of implementation, B2W is the first weight vector determined by B2 based on the ecological recovery goal and the initial stage of implementation. D1-B1 To reduce the pollution entering the river (D1) based on the second weight vector under the feedback index B1, W D2-B1 To regulate the internal pollution of the river (D2), based on the second weight vector under the feedback index B1, W D1-B2 To reduce the pollution entering the river (D1), the second weight vector based on the feedback index B2 is ...

[0065] Table 5 Comprehensive weight calculation table of each scheme

[0066]

[0067] Step S110, determining the target implementation plan based on the ranking of the comprehensive weights.

[0068] Specifically, based on the ranking of comprehensive weights, the implementation plan that best meets the goal of ecological recovery can be selected, providing a scientific basis for decision makers.

[0069] The present invention provides an evaluation method for a water area ecological recovery plan, comprising: obtaining an ecological recovery target of a target water area and an implementation start stage of protection of the target water area; determining a first scale matrix of feedback indicators corresponding to the target water area based on the ecological recovery target and the implementation start stage; wherein the feedback indicators include at least one of the following: physicochemical indicators, nutrient salt indicators, unconventional indicators, hydraulic indicators and biological indicators; determining a second scale matrix of a protection plan based on the target feedback indicators; obtaining multiple weight vectors after fuzzy consistency processing and normalization processing are performed on multiple scale matrices in turn, and determining a comprehensive weight based on the multiple weight vectors; wherein the scale matrix includes a first scale matrix and a second scale matrix; determining a target protection plan based on the ranking of the comprehensive weights; scaling the water area feedback indicators and the protection plan, and then determining the comprehensive weight of the scale matrix based on a fuzzy consistency algorithm, determining the target protection plan, clarifying the starting point of the water area ecological recovery, paying full attention to the feedback indicators, determining different protection plans for different recovery stages, reducing resource waste, and improving the efficiency of water area ecological recovery.

[0070] Embodiment 2

[0071] Based on the above embodiments, the embodiments of the present invention provide another method for evaluating water ecological restoration programs, wherein the feedback indicators include at least one sub-feedback indicator; wherein the physical and chemical indicators include at least one of the following sub-feedback indicators: odor, transparency, dissolved oxygen and chemical oxygen demand; the nutrient salt indicators include at least one of the following sub-feedback indicators: ammonia nitrogen, total phosphorus, total nitrogen; the unconventional indicators include the sub-feedback indicators: heavy metals; the hydraulic indicators include at least one of the following sub-feedback indicators: flow rate and water level; the biological indicators include the sub-feedback indicators: biodiversity, exemplarily, the sub-feedback indicator evaluation system for polluted water sections shown in Table 6.

[0072] Table 6 Feedback index evaluation system for polluted water section

[0073]

[0074] See also Figure 2 The flowchart of another method for evaluating aquatic ecological restoration scheme provided by an embodiment of the present invention is shown, and the method includes:

[0075] Step S202, obtaining the ecological recovery target of the target water area and the implementation start phase of the protection of the target water area.

[0076] Step S204, determining a first scaling matrix of feedback indicators corresponding to the target water area based on the ecological recovery target and the implementation start stage.

[0077] Among them, the feedback indicators include at least one of the following: physical and chemical indicators, nutrient indicators, unconventional indicators, hydraulic indicators and biological indicators.

[0078] Step S206: Select one of the sub-feedback indicators from at least one of the sub-feedback indicators as the target feedback indicator.

[0079] Step S208: determining a second scaling matrix of the protection scheme based on the target feedback index.

[0080] Specifically, a sub-feedback indicator is selected as the target feedback indicator, and the elements under the target feedback indicator are analyzed pairwise based on the 0.1-0.9 scaling method shown in Table 2, and the weight values ​​are calculated. Another sub-feedback indicator is continuously selected as the target feedback indicator until the scaling of the protection scheme is completed under all the feedback indicators.

[0081] Step S210: determining a third scaling matrix of sub-feedback indicators corresponding to the target water area based on the ecological recovery target and the implementation start stage.

[0082] Step S212, performing fuzzy consistency processing and normalization processing on multiple scale matrices in turn to obtain multiple weight vectors, and determining a comprehensive weight based on the multiple weight vectors.

[0083] Specifically, by calculating the comprehensive weight value of each sub-feedback indicator, the comprehensive weight value W' of the sub-feedback factor for reducing the pollution entering the river from the basin can be obtained. Taking the reduction of pollution entering the river from the basin as an example, the calculation public notice and form are shown in Table 7.

[0084] For details, see W in Table 7 B1 To W B14 , W B21 To W B23 , W B31 , W B41 , W B42 and W B51 are all weight vectors of sub-feedback indicators calculated based on the elements in the third scaling matrix; W B11 W is the third weight vector determined by B11 based on the ecological recovery goal and the initial stage of implementation. B12 The third weight vector determined by B12 based on the ecological recovery target and the implementation start stage…Step S214, determining the target protection plan based on the ranking of the comprehensive weights.

[0086]

[0087] Furthermore, combined with the comprehensive weight values ​​in Table 7, the comprehensive weight values ​​of the alternatives relative to the target layer are calculated, as shown in Table 8, where W” represents the comprehensive weight. In Table 8, W D1-B11 To reduce the pollution entering the river (D1) based on the second weight vector under the sub-feedback index B11, W D2-B11 To regulate the internal pollution of the river (D2), based on the second weight vector under the feedback index B11, W D1-B13 To reduce the pollution entering the river (D1), the second weight vector based on the feedback index B12 is used...

[0088] Table 8 Comprehensive weight calculation table of each scheme

[0089]

[0090] Specifically, based on the comprehensive weight ranking of each plan, the importance and priority of each implementation plan for achieving ecological recovery of polluted waters are obtained.

[0091] Furthermore, according to the selected implementation plan and the indicator with the highest weight in the corresponding stage, if the indicator meets the requirements, it is deemed to have completed the implementation plan, and then the next stage of implementation is evaluated according to steps S202 to S222; if the preferred feedback indicator does not meet the standard, the feedback indicator and the implementation plan weight are recalculated according to the current water pollution characteristics feedback. Such as: the restoration goal is to eliminate black and odorous water bodies. Sort by the weight of the sub-feedback indicators, the larger the weight value, the higher the priority of the assessment. Corresponding to the scale scoring, the weight value is large, and the scale scoring shows that the important indicators are of high importance, that is, they must meet the standards; the weight value is small and the importance is strong or the weight value is large and the importance is weak, it is enough to be close to the standard; the weight value is small and the importance is weak, no requirements are made for indicators. And so on, until the final goal is reached.

[0092] Furthermore, an embodiment of the present invention provides a method for determining the evaluation order of sub-feedback indicators based on comprehensive subjective and objective weights.

[0093] Specifically, the subjective weight is the comprehensive weight of the sub-feedback indicators calculated in Table 7; the objective weight is calculated based on the entropy weight method.

[0094] For example, if m sub-feedback indicators have obtained n years of data, then for each indicator, the proportion of the value of each year to the total value is P i , the formula is as follows:

[0095] Information entropy of each indicator:

[0096]

[0097] Among them, P i is the proportion of the value of each indicator in each year to the total value, and E is the information entropy of each indicator.

[0098] Information redundancy of each indicator:

[0099] T = 1-E;

[0100] Among them, T is the information redundancy.

[0101] Objective weight of each indicator:

[0102]

[0103] Among them, wo is the objective weight, m ​​is the number of indicators, T j is the information redundancy of the j-th indicator.

[0104] The subjective and objective weights are combined, taking into account the subjectivity of decision makers and the objective deviation of data, and the subjective weights and objective weights are combined to obtain the comprehensive weights of sub-indicators. The specific method is as follows:

[0105] The weight matrix is ​​composed of subjective and objective weights, and the formula is as follows:

[0106]

[0107] [W T W]=ρU;

[0108] Among them, ρ is the maximum eigenvalue, U=[u1,u2] T is the corresponding feature vector, W is the comprehensive weight, wo1 to wo 11 Corresponding to the objective weights of the previous 11 sub-indicators.

[0109] According to the eigenvector U, the subjective and objective weights are linearly added to obtain the combined weight wc of all indicators. The formula is as follows:

[0110] wc j =u1·W′ j +u2·wo j ;

[0111] Among them, wc j is the comprehensive weight of the jth indicator, u1 is the first parameter, u2 is the second parameter, wo j is the objective weight of the jth indicator.

[0112] Normalize wc to obtain the comprehensive subjective and objective weights of each sub-feedback indicator.

[0113] Determine the assessment priority of sub-feedback indicators based on the ranking of comprehensive subjective and objective weights.

[0114] The embodiment of the present invention provides a method for evaluating a water ecological recovery program, and applies a feedback mechanism in the implementation process of ecological recovery of polluted waters in a river basin. According to different water characteristics, fuzzy multi-level analysis is adopted to optimize the indicators of greatest concern and the most effective implementation plan in the river basin according to local conditions. A feedback mechanism in the implementation process of ecological recovery of polluted waters in a river basin is formed, which can not only make decisions according to local conditions, but also adjust real-time plans and goals in real time, with strong flexibility and accuracy. The priority and importance of implementation plans and indicators of concern are determined based on this.
