When ZFi1When the station water level is equal to 0, namely the station water level is just equal to the guaranteed water level at this moment, the station water level is considered to be at the critical point of 'fit' and 'not fit'. For convenience of understanding, the index system adopts 60 points as the critical points of 'fit' and 'not fit'. At the same time, the upper bound of the index is 1, so the interval (0, 1)]Assigned regions (60, 100) can be determined]The slope is used to determine the assigned interval (0, 60)]The corresponding index value is that-1.5 corresponds to 0 point, when the index value is lower than-1.5, the water level safety degree is considered to be extremely poor, 0 point is assigned, no distinction is made, and other indexes are assigned according to the rule.

The information processing and analyzing module collects real-time data of the flood control representative station collecting unit, the water supply representative station collecting unit and the water ecological environment collecting unit, gives weights to multiple groups of data and finally outputs analysis data to the weight distribution unit of the information feedback module. When the data is summarized, the data is divided into a plurality of groups according to different attributes to form different levels, elements in the same level are used as criteria to dominate certain elements in the next level, and the elements are dominated by the elements in the previous level, and the top-to-bottom domination relationship forms a hierarchical level.
And then, comparing every two indexes to obtain the relative importance of a single index, and constructing a judgment matrix W.
And finally, determining the weight and checking the consistency. For the determination matrix W, the calculation satisfies AW ═ λmaxMaximum eigenvalue λ of WmaxAnd its corresponding feature vector a. In the construction of the judgment matrix, it is not required that the judgment has transitivity and consistency, which is determined by the complexity of objective things and the diversity of human recognition. However, since it is required to limit the deviation of the judgment matrix within a certain range so that the matrix satisfies substantial consistency, the consistency of the judgment matrix is checked. The matrix consistency index CI and the consistency ratio CR are respectively obtained by the following formula:
Figure BDA0002636265010000143
Figure BDA0002636265010000151
in the formula: RI is an average random consistency index, the magnitude of which is related to the number n of evaluation factors, and the value can be obtained by looking up a table 11. Generally, the smaller the consistency ratio CR, the better the consistency of the judgment matrix. When CR is less than 0.1, judging that the consistency is acceptable, and using the characteristic vector as a weight vector; when CR is more than or equal to 0.1, the judgment matrix needs to be adjusted and corrected to ensure that CR is less than 0.1, and the consistency is satisfied. When n is less than 3, the judgment matrix always has complete consistency.

2、4、6、8 Intermediate value of the above two adjacent judgments
The river, lake and water system communication regulation and control needs to comprehensively guarantee flood control safety, water supply safety and water ecological environment safety of a drainage basin and a drainage basin, and considering that the drainage basin and the drainage basin are different in terms of flood control, water supply and water ecological environment under different water conditions, the technology respectively takes a flood control water level and a drought limit water level as boundaries, and when the water level exceeds the flood control water level, the river, lake and water system communication regulation and control is considered to be mainly based on a flood control safety target; when the water level is between the flood control water level and the drought limiting water level, the ecological environment safety is considered as the main reason for the communication regulation of the rivers and the lakes; when the water level is lower than the drought limit water level, the river and lake water system is considered to be communicated and controlled to mainly supply water safely.
As shown in fig. 3, different water regimes are divided according to water level: (1) flood control safety guarantee period: the water level is above the flood control water level, and the flood control safety target is mainly used for communicating and controlling the rivers and the lakes; (2) water ecological environment safety guarantee period: the water level is between the flood control water level and the water supply control water level, and the water ecological environment safety target is prior to the flood control target and the water supply safety target; (4) the water level is below the water level of 2.8m, and the basin water safety mainly aims at water supply safety.
(1) Flood control safety guarantee period
The guarantee of flood control safety is in absolute priority position in the flood control safety guarantee period, and water supply safety and water ecological environment safety need to be considered comprehensively on the premise of next time. In the guarantee period, the water requirements of activities such as regional industry, agriculture, life and the like can be usually met, but the water quality safety of a drinking water source area still needs to be ensured, and the water ecological environment safety guarantee is concerned. And judging the importance level of the matrix, wherein the ratio of flood control safety to water supply safety is absolutely important, the weight ratio is 9:1, the ratio of flood control safety to water ecological environment safety is very important, the weight ratio is 7:1, the water ecological environment safety is slightly more important than the water supply safety, and the weight ratio is 3: 1.
In the flood control safety evaluation indexes, the flood control station water level safety degree is as important as the regional flood discharge ordering degree, so that the weight ratio of the station water level safety degree to the regional flood discharge ordering degree is 1:1, the station water level safety degree to the regional flood discharge ordering degree is slightly more important than the adaptation degree of the flood discharge capacity of the drainage project, and the weight ratio is respectively set to be 4:1 and 3: 1. In the flood control safety guarantee period, the water level is relatively high, the water source area water quality index in the water supply safety index is the most important in scale, the water diversion project water diversion supply satisfaction degree is obtained, the water supply representative station water level satisfaction degree is obtained again, and the weight ratio is set as shown in a table. In the flood control safety guarantee period, in the water ecological environment safety indexes, the representative section water quality index reaches the position which is respectively more and slightly more important than the diversion project water supply satisfaction degree and the flow rate suitability degree/ecological flow satisfaction degree, so the weight ratio is respectively 5:1 and 3:1, and the flow rate suitability degree/ecological flow satisfaction degree is slightly more important than the diversion project water supply satisfaction degree at the moment, and the weight ratio is 3: 1.

(2) Water ecological environment safety guarantee period
In the water ecological environment safety guarantee period, the river and lake water system communication water safety adaptation evaluation takes the guarantee of water ecological environment safety as the center of gravity, and simultaneously takes flood control safety and water supply safety into consideration, but the flood control safety is slightly more important than the water supply safety. The safety of water ecological environment is important relative to the safety of flood control and important relative to the safety of water supply. The importance of indexes under each object layer is slightly inconsistent with the flood control safety guarantee period.
