Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] like Figure 1 As shown:

[0049] Embodiment 1: The present invention provides an interactive ecological water replenishment system for surface and groundwater, comprising:

[0050] Surface water collection module, used to collect and store water resources from surface water sources;

[0051] The groundwater extraction module is used to extract groundwater from the aquifer and is equipped with a groundwater level intelligent control unit.

[0056] As can be seen from the above, this system integrates multiple key modules to achieve efficient and sustainable water resource management; the surface water collection module is responsible for collecting and storing surface water sources, while the groundwater extraction module intelligently monitors and regulates the dynamic changes of groundwater levels to ensure sustainable groundwater extraction; the water quality treatment module purifies surface water and groundwater to meet strict ecological water replenishment standards; the intelligent control module is the core, and intelligently adjusts the mixing ratio of surface water and groundwater and the timing of water replenishment according to water quantity, water quality and water replenishment needs; the water replenishment and transportation module is responsible for accurately transporting treated water resources to rivers, lakes, wetlands and groundwater recharge areas; at the same time, the monitoring and feedback module continuously monitors the water replenishment effect and ecological impact, provides real-time data support for intelligent control, and continuously optimizes water replenishment and groundwater management strategies.

[0057] Example 2: This example is basically the same as the previous example, except that the groundwater extraction module uses the following steps to calculate the groundwater extraction amount:

[0058] Step 1: Real-time monitoring of groundwater level h(t):

[0059] Real-time groundwater level data is obtained through the groundwater level intelligent control unit to provide basic information for subsequent steps;

[0060] Step 2: Based on the groundwater level data obtained in step 1, construct the function g(h(t)) of groundwater level change over time:

[0061] Use real-time monitoring data to construct a function describing the change of groundwater level over time. Based on the real-time monitored groundwater level data, construct a function g(h(t)) describing the change of groundwater level over time.

[0062] Step 3: Set the groundwater level threshold H thres , and judge whether the current groundwater level is lower than the threshold:

[0063] A reasonable groundwater level threshold H is set by the groundwater level intelligent control unit thres ,When the monitored groundwater level is lower than this threshold, the system will enter the groundwater extraction phase;

[0064] Step 4: Calculate the optimal groundwater extraction amount Q according to the optimization algorithm gw (t):

[0068] Specifically, the mathematical model used to calculate groundwater extraction is as follows:

[0069]

[0070] Among them, Q gw (t) represents the optimal extraction amount of the groundwater extraction module within time t; g(h(t)) represents the function of groundwater level changing with time, h(t) represents the groundwater level; H thres Indicates the groundwater level threshold, below which groundwater extraction is required; Q max represents the maximum amount of groundwater extraction; C(x) represents the groundwater extraction cost function, including energy consumption and equipment wear; x represents the decision variable of groundwater extraction; Q gw The range of (t) is [0, Q max ], indicating that groundwater extraction is restricted;

[0071] The specific application process of the above formula is as follows:

[0072] 1. Model initialization and data preparation

[0073] Collect historical data:

[0074] Historical groundwater level data: used to construct the function g(h(t)) of groundwater level change over time.

[0075] Groundwater extraction cost data: including energy consumption, equipment wear, etc., used to construct the groundwater extraction cost function C(x).

[0076] Setting parameters:

[0077] Groundwater level threshold H thres : Set according to ecological and geological conditions, groundwater extraction is required below this value.

[0078] Maximum groundwater extraction Q max : Set according to the water storage capacity of the aquifer and the principle of sustainable utilization.

[0079] 2. Building and Optimizing Models

[0080] Construct a groundwater level change function:

[0081] Using historical groundwater level data, time series analysis, regression analysis and other methods are used to construct the function g(h(t)) of groundwater level change over time.

[0082] Construct a groundwater extraction cost function:

[0083] Based on data such as energy consumption and equipment wear during groundwater extraction, a groundwater extraction cost function C(x) is constructed. This function should reflect the relationship between the extraction volume x and the cost.

[0084] Substitute into the formula to calculate:

[0085] The constructed groundwater level change function g(h(t)) and the set groundwater level threshold H thres , the maximum groundwater extraction amount Q max and groundwater extraction cost function C(x) into Eq.

[0086] In the time interval [0, T], the formula is integrated and calculated to solve the optimal groundwater extraction amount Q gw (t).

[0087] 3. Implementation and Optimization Strategy

[0088] Create an extraction plan:

[0089] According to the calculated optimal groundwater extraction amount Q gw (t), Develop a groundwater extraction plan.

[0090] The plan should include specific contents such as extraction time, extraction amount, and extraction method.

[0091] Implement the extraction operation:

[0092] According to the extraction plan, start the groundwater extraction equipment and carry out groundwater extraction operations.

[0093] During the extraction process, the groundwater level changes are monitored in real time to ensure that the extraction volume does not exceed Q max , and avoid adverse impacts on the geological environment.

[0094] Monitoring and Feedback:

[0095] After the extraction operation, monitoring equipment is used to monitor the water quantity, water quality and ecological environment changes in the water replenishment area in real time.

[0096] The monitoring data is fed back to the intelligent control module to evaluate the extraction effect and the impact on the ecological environment.

[0097] Based on the feedback, extraction plans are adjusted and optimized to achieve more efficient and sustainable groundwater management.

[0098] Consider recharging strategies:

[0099] In some cases, groundwater recharge operations may be necessary to maintain groundwater table stability or meet specific ecological recharge needs.

[0100] The amount of recharge should be determined based on water replenishment needs and surface water resources, and incorporated into the overall water resources management strategy.

[0101] As can be seen from the above, this embodiment discloses an optimized calculation of groundwater extraction volume through intelligent regulation. First, the system monitors the groundwater level in real time and constructs a function of the groundwater level change over time. Then, a reasonable groundwater level threshold is set. When the monitored water level is lower than this threshold, the system will start the groundwater extraction program. During this process, the groundwater level intelligent regulation unit uses an optimization algorithm to comprehensively consider factors such as groundwater level changes, extraction costs, and maximum extraction volume to calculate the optimal groundwater extraction volume, so as to ensure that the groundwater level is stable and the extraction cost is minimized while meeting the water replenishment demand. In addition, the system will also intelligently decide whether groundwater recharge is needed and calculate the corresponding recharge volume based on the water replenishment demand and surface water resource conditions.

[0107] Specifically, the water replenishment and delivery module further includes:

[0108] The pipeline optimization layout system optimizes the layout of the pipeline according to the topography, landform and water resource distribution of the water replenishment area, reducing water resource loss and energy consumption during the transportation process.

[0109] Specifically, the monitoring and feedback module also includes:

[0110] The ecological and environmental impact assessment system is used to evaluate the impact of water replenishment operations on the ecological environment of the replenishment area, including biodiversity, soil moisture, and vegetation growth indicators, to ensure that water replenishment activities will not have a negative impact on the ecological environment.

[0111] Specifically, the groundwater level prediction module uses a machine learning algorithm to perform predictions, specifically including:

[0112] In the data preprocessing stage, the historical groundwater level data are cleaned and normalized;

[0113] In the feature selection stage, key factors affecting groundwater level changes are extracted from the processed data;

[0115] In the prediction application stage, real-time groundwater level data is input into the trained model, and the prediction results of future groundwater levels are output.

[0116] As can be seen from the above, in this embodiment, the intelligent control module has added a groundwater level prediction module. This module uses machine learning algorithms to achieve accurate prediction of future groundwater levels through preprocessing of historical data, feature selection, and model training, so that water replenishment strategies and groundwater extraction plans can be adjusted in advance; the water quality treatment module has added a water quality monitoring and regulation unit to monitor and optimize water quality in real time to ensure the quality of ecological water replenishment; the water replenishment and transportation module optimizes the layout system of the transportation pipeline to reduce transportation losses according to the topography and water resource distribution; in addition, the monitoring and feedback module has added an ecological and environmental impact assessment system to comprehensively evaluate the potential impact of water replenishment activities on the ecological environment.
