and step 121, obtaining the upstream-downstream relation between the water storage projects according to the position data of the water storage projects.
It will be appreciated that in a river flow field, there will be a plurality of impoundment projects at different positions, where there will be a relationship between impoundment projects at different positions in a position that is upstream and downstream, where impoundment projects at an upstream position will affect hydrographic indicators such as impoundment reservoir capacity of impoundment projects at a downstream position, that is, there is a hydraulic connection between impoundment projects at an upstream position and impoundment projects at a downstream position.

Can be used forIt is understood that because in the river flow field, various hydraulic connection modes such as series connection, parallel connection, series-parallel connection and the like exist among various water storage projects, in the embodiment of the application, the regional water resource regulation and control capability under the superposition influence of three elements including hydraulic connection, water storage reservoir capacity and rain area can be comprehensively evaluated through the water storage modulus. Specifically, the water storage modulus is defined as the water storage volume per unit area in the rain collecting range of water storage engineering, and the unit is m3/km 2 Or ten thousand m3/km 2 . In addition, as the definition form and physical meaning of the water storage modulus have the same mathematical paradigm as the hydrologic indexes such as the conventional water production modulus, irrigation modulus and the like, the water storage modulus can be directly subjected to numerical operation and superposition analysis with the water storage modulus, so that the water storage modulus can be applied to water resource analysis in different scenes. For example, the water storage modulus can be calculated with the water production modulus, in particular, division operation can be performed between the water storage modulus and the water production modulus, the obtained quotient can be used as the adjusting coefficient of the water storage project corresponding to the water storage modulus, the adjusting coefficient can quantitatively analyze the water storage adjusting capability of the water storage unit, and the construction planning of the water storage project is facilitated.
It can be understood that the upstream and downstream relations between the water storage projects can be identified in the form of an association matrix, so that a corresponding relation is established between each water storage project, and various implementation modes exist. Specifically, referring to fig. 2, in a certain river flow area shown in fig. 2, a series-parallel hydraulic connection manner exists among the water storage project A1, the water storage project A2 and the water storage project A3, the water storage project A1 is used as a downstream water storage project in the river flow area, the water storage project A2 and the water storage project A3 are used as an upstream water storage project of the water storage project A1, and then the water storage modulus of the water storage project A1 can be obtained by the following formula:
wherein V is 1 Is the water storage capacity of the water storage engineering A1, S 1 Is the rain collecting range of the water storage project A1, M A1 The water storage modulus is the water storage modulus of the water storage engineering A1.
The water storage modulus of the water storage engineering A2 can be obtained by the following formula:
wherein V is 2 Is the water storage capacity of the water storage engineering A2, S 2 Is the rain collecting range of the water storage project A2, M A2 The water storage modulus is the water storage modulus of the water storage engineering A2.
It can be understood that the water storage modulus of the water storage engineering V3 can be obtained by analogy from the above description, and in practice, the number of water storage engineering in the river basin is often large, and the process of obtaining the water storage modulus of each water storage engineering in the river basin according to the upstream-downstream relationship can be circulated until the water storage modulus of each water storage engineering in the river basin is obtained, and the water storage moduli of each water storage unit are summarized, which is not described in detail herein.
130, carrying out spatial distribution analysis and regulation and control capability grading on regional water resources of the river basin according to the water storage modulus of each water storage project;
it can be understood that if the water storage capacity adopts the Xingli water storage capacity, the Xingli water storage module is obtained, and the runoff regulation capacity analysis on the spatial distribution scale can be performed on the regional water resources of the river basin; if the water storage capacity is the flood control water storage capacity, flood control capacity analysis in flood season on the scale of spatial distribution of regional water resources of river basin can be performed; if the water storage capacity adopts the dead water storage capacity, the water resource emergency regulation and control capacity analysis on the scale of spatial distribution of regional water resources of river basin can be performed. Specifically, in the embodiment of the application, the change condition of regional water resource regulation and control capability, the change condition of spatial distribution and the like of the river basin can be analyzed by combining relevant historical hydrologic data; or analyzing the current regional water resource regulation capacity condition, the current spatial distribution condition and the like of the river basin according to the current water storage modulus, and displaying the spatial distribution analysis result by a visual diagram; meanwhile, the water storage modulus under the influence of the superposition of future planning projects can be superposed to analyze the water resource regulation capacity condition and the spatial distribution condition of the future area of the river basin. It is worth to say that the regional water resources in the river flow area are analyzed through the water storage modulus, the time evolution and the spatial distribution condition of the regional water resources can be reflected well, and the accuracy of the analysis result is high.
Step 130, classifying the regulation and control capability of the regional water resources of the river basin according to the water storage modulus of each water storage project, including:
step 131, acquiring an regional water resource regulation and control capability evaluation table of the river basin;
step 131, obtaining an regional water resource regulation and control capability evaluation table of the river basin, which comprises the following steps:
step 1311, acquiring a reservoir capacity coefficient index and a water production modulus in the river flow field;
and 1312, obtaining an regional water resource regulation and control capability evaluation table of the river basin according to the reservoir capacity coefficient index and the water production modulus index.
And 132, analyzing the water storage modulus of each water storage project according to the regional water resource regulation and control capability evaluation table to obtain the regional water resource regulation and control capability grade of the river basin.
It will be appreciated that the index of the storage capacity coefficient is shown in the following table:
TABLE 1
Wherein beta is the storage capacity coefficient of the water storage engineering.
It can be understood that the regional water resource regulation and control capability evaluation table classifies the regional water resource regulation and control capability represented by the water storage modulus, and can be obtained by deduction according to the definition of the water storage modulus, and the water storage modulus can be obtained by the following formula:
M A ＝M r ×β
wherein M is A For the water storage modulus of a certain water storage project, M r The water production modulus is the area of a certain water storage project, and beta is the storage capacity coefficient of a certain water storage project.
It can be understood that the water production modulus of each area will have a certain difference due to the difference of the areas where the water storage projects are located, in particular, the water production modulus M of a certain area r 105 km/km of ten thousand m3 2 And obtaining a regional water resource regulation and control capability evaluation table according to the formula and the reservoir capacity coefficient index, wherein the regional water resource regulation and control capability evaluation table is as follows:
TABLE 2
| Water storage modulus M A | Capability index |
| M A ＜2.1 | Without regulation ability |
| 2.1≤M A ＜3.15 | Day adjustment capability |
| 3.15≤M A ＜8.4 | Month adjusting ability |
| 8.4≤M A ＜21 | Quaternary conditioning capacity |
| 21≤M A ＜31.5 | Incomplete annual capacity |
| 31.5≤M A ＜52.5 | Full annual capacity |
| M A ≥52.5 | Ability to adjust for many years |
It can be understood that the obtained water storage modulus can be analyzed according to the regional water resource regulation capability evaluation table to obtain the regional water resource regulation capability level of the corresponding water storage project, and the obtained regional water resource regulation capability level can be integrally displayed with the spatial distribution schematic diagram obtained by spatial distribution analysis, so that redundant description of the application is omitted. It is worth to say that, after the regional water resource regulation capability level of all the water storage projects in the river basin is obtained, the regional water resource regulation capability level of the river basin can be obtained only by simple analysis, and the application is not redundant herein.
