Technical Field

[0001] This application relates to the technical field of water resource allocation, and in particular to a method, apparatus, equipment, medium and product for water intake and allocation. Background Technology

[0002] With the uneven distribution of global water resources and the continuous growth of human water demand, some regions have increasingly diversified water source types, including Class I external water transfer, Class II external water transfer, reclaimed water, local surface water and groundwater, etc. Moreover, the water supply range and water demand of each water source are complex. Therefore, the rational allocation and management of water resources in complex water network areas has become an urgent problem to be solved.

[0003] In related technologies, the water supply allocation for each water source corresponding to each water user in the target area is usually estimated based on the annual water supply of each water source and the annual water consumption of each water user in the target area, which are disclosed by relevant departments. However, there is a problem with the accuracy of determining the water supply allocation for each water source corresponding to each water user in the target area. Summary of the Invention

[0004] Therefore, it is necessary to provide a water intake and distribution method, device, equipment, medium, and product to address the aforementioned technical problems, which can improve the accuracy of determining the water supply distribution volume for each water-using sector and corresponding water source in the target area.

[0005] In a first aspect, this application provides a method for distributing water use, the method comprising:

[0006] For each water-using sector in the target area, identify at least one water supply source corresponding to that sector.

The determination step includes determining the daily water supply volume of the water source to the water user from the daily water supply surplus and a first parameter, and determining the new daily water demand of the water user based on the daily water supply volume of the water source. The first parameter is the product of the water user's water intake coefficient from the water source and the water user's daily water demand.

[0008] The new daily water demand is used as the daily water demand of the water-using sector. The determination steps are then performed on other priority water sources in sequence to determine the maximum daily water supply to the water-using sector for each priority water source.

[0009] In one embodiment, the method further includes:

[0023] When the water-using sector is classified as a domestic water-using sector, the daily water demand of the domestic water-using sector is determined based on the ratio of the population of the target area to the total population of the corresponding superior area, the historical annual total water consumption of the domestic water-using sector, and the domestic water demand allocation coefficient.

[0024] When the water-using sector is industrial, the daily water demand of the industrial water-using sector is determined based on the ratio of the population of the target area to the total population of the corresponding superior area, the historical annual water consumption of the industrial water-using sector, and the industrial water demand allocation coefficient.

[0025] When the water-using sector is agricultural, the daily water demand of the agricultural sector is determined based on the historical annual total water consumption of the agricultural sector and the agricultural demand allocation coefficient.

[0026] Secondly, this application also provides a water intake and distribution device, which includes:

[0027] The water supply source determination module is used to determine at least one water supply source for each water-using sector in the target area.

[0028] The remaining demand determination module is used to perform a determination step for the first priority water supply source among the various water supply sources. The determination step includes determining the daily water supply volume of the water supply source to the water user department from the daily remaining water supply volume of the water supply source and a first parameter, and determining the new daily remaining water demand of the water user department based on the daily water supply volume of the water supply source; the first parameter is the product of the water user department's water intake coefficient from the water supply source and the water user department's daily remaining water demand.

[0029] The daily water supply determination module is used to take the new daily water demand as the daily water demand of the water-using department, and then perform determination steps on other priority water sources in sequence to determine the maximum daily water supply of each priority water source to the water-using department.

[0031] For each water-using sector in the target area, identify at least one water supply source corresponding to that sector.

[0032] For the first priority water source among all water supply sources, a determination step is performed. The determination step includes determining the daily water supply volume of the water source to the water user from the daily water supply surplus and a first parameter, and determining the new daily water demand of the water user based on the daily water supply volume of the water source. The first parameter is the product of the water user's water intake coefficient from the water source and the water user's daily water demand.

[0033] The new daily water demand is used as the daily water demand of the water-using sector. The determination steps are then performed on other priority water sources in sequence to determine the maximum daily water supply to the water-using sector for each priority water source.

[0036] For the first priority water source among all water supply sources, a determination step is performed. The determination step includes determining the daily water supply volume of the water source to the water user from the daily water supply surplus and a first parameter, and determining the new daily water demand of the water user based on the daily water supply volume of the water source. The first parameter is the product of the water user's water intake coefficient from the water source and the water user's daily water demand.

[0037] The new daily water demand is used as the daily water demand of the water-using sector. The determination steps are then performed on other priority water sources in sequence to determine the maximum daily water supply to the water-using sector for each priority water source.

[0038] Fifthly, this application also provides a computer program product comprising a computer program that, when executed by a processor, performs the following steps:

[0039] For each water-using sector in the target area, identify at least one water supply source corresponding to that sector.

[0040] For the first priority water source among all water supply sources, a determination step is performed. The determination step includes determining the daily water supply volume of the water source to the water user from the daily water supply surplus and a first parameter, and determining the new daily water demand of the water user based on the daily water supply volume of the water source. The first parameter is the product of the water user's water intake coefficient from the water source and the water user's daily water demand.

[0041] The new daily water demand is used as the daily water demand of the water-using sector. The determination steps are then performed on other priority water sources in sequence to determine the maximum daily water supply to the water-using sector for each priority water source.

[0042] The aforementioned water intake and distribution method, apparatus, equipment, medium, and product first determine at least one water supply source corresponding to each water-using sector in the target area; then, for the first priority water supply source among all water supply sources, a determination step is performed, which includes determining the daily water supply volume of the water supply source to the water-using sector from the daily remaining water supply volume of the water supply source and a first parameter, and determining the new daily remaining water demand of the water-using sector based on the daily water supply volume of the water supply source; the first parameter is the product of the water intake coefficient of the water-using sector from the water supply source and the daily remaining water demand of the water-using sector; then, the new daily remaining water demand is used as the daily remaining water demand of the water-using sector, and the determination step is performed sequentially for other priority water supply sources to determine the maximum daily water supply volume of each priority water supply source to the water-using sector. Thus, by considering the priority of water supply sources and the remaining demand of water-using sectors, and by iteratively adjusting the allocation scheme in real time based on the daily remaining water supply and daily remaining water demand, the accuracy and reliability of water supply allocation for each water-using sector in the target area under a complex water network can be improved, while also enhancing the flexibility of water resource allocation.

[0050] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0051] The water intake and allocation method provided in this application embodiment can be applied to terminal devices such as computers and laptops. The terminal device can execute the water intake and allocation method provided in the embodiment based on the historical water resource data of the target area to obtain the daily water supply that each water source can provide for each water-using sector in the target area. Specifically, the terminal device first determines at least one water source corresponding to each water-using sector in the target area; then, for the first priority water source among the water sources, it performs a determination step, which includes determining the daily water supply from the water source to the water-using sector from the daily remaining water supply and a first parameter, and determining the new daily remaining water demand of the water-using sector based on the daily water supply; the first parameter is the product of the water intake coefficient of the water-using sector from the water source and the daily remaining water demand of the water-using sector; then, the new daily remaining water demand is used as the daily remaining water demand of the water-using sector, and the determination step is performed sequentially for other priority water sources to determine the maximum daily water supply from each priority water source to the water-using sector.

[0052] In one embodiment, such as Figure 1 As shown, this method is illustrated using the aforementioned terminal device as an example. It can be understood that this method can also be applied to a server, and further to a system including both a terminal and a server, and is implemented through interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0053] Step 102: For each water-using sector in the target area, determine at least one water supply source corresponding to that sector.

[0054] The target area is a general area with clearly defined boundaries and water demand, divided into sub-areas according to certain rules. For example, it can be a city, or a district or street within a city. Water users are different types of units within the target area that have water demand, typically including but not limited to domestic water users (e.g., residential areas), industrial water users (e.g., river and lake replenishment, ecological greening), agricultural water users (e.g., farmland, livestock farms), and ecological water users (e.g., parks and other ecological areas). Water sources are the sources of water resources provided to water users, generally including Class I external water transfers (inter-regional water transfers), Class II external water transfers (inter-river water transfers), reclaimed water (treated wastewater that can be reused), local surface water, and groundwater. Among these sources, Class II external water transfers and local surface water can simultaneously supply water to domestic, industrial, agricultural, and ecological water users; Class I external water transfers supply water to all water users except agricultural users; groundwater supplies water to all water users except ecological users; and reclaimed water is mainly used to replenish water for ecological users.

[0055] Optionally, relevant information on water-using sectors and water sources in the target area can be collected first, including the distribution, type, and scale of water use, as well as the location, volume, and type of water sources. Then, based on the geographical location, water demand characteristics, and the distribution and supply capacity of water sources, at least one water source can be determined for each water-using sector. In determining the at least one water source for each water-using sector, the priority of the sector can be used to sequentially determine the at least one water source for each sector. The priority of the water-using sectors can be determined based on experience; for example, in this embodiment, the priority of the water-using sectors from high to low is: domestic water use, industrial water use, agricultural water use, and ecological water use.

[0056] Step 104: For the first priority water supply source among the water supply sources, perform the determination step, which includes determining the daily water supply volume of the water supply source to the water user department from the daily water supply surplus and the first parameter, and determining the new daily water demand of the water user department based on the daily water supply volume of the water supply source.

[0057] Among all water sources, the first priority water source is the one with the highest priority. The priority of the water source determines the order in which it supplies water to the corresponding water-using departments. The priority of the water source can also be determined based on experience. For example, in this embodiment, the priority of the water sources from highest to lowest is reclaimed water, Class I externally diverted water, Class II externally diverted water, local surface water, and groundwater. The first parameter is the product of the water-using department's water extraction coefficient from the water source and the department's daily remaining water demand. This first parameter is used to comprehensively consider the remaining demand of the water-using department and the allocation weight of the water source when determining the daily water supply from the water source, thereby allocating water resources more rationally.

[0058] The water intake coefficient reflects the degree of dependence or allocation ratio of water-using sectors on water supply sources. Initially, the water intake coefficient is a range value set based on experience. At the beginning of the iteration, preliminary water resource allocation can be performed based on the range value of the water intake coefficient. Then, based on the water demand satisfaction of water-using sectors and the usage of water supply sources after each allocation, the water intake coefficient is adjusted according to feedback. By repeating the above feedback adjustment process multiple times, the water intake coefficient is continuously optimized. As the number of iterations increases, the water intake coefficient will gradually converge to a suitable value, so that the water resource allocation reaches a relatively optimal state, that is, it can both meet the basic water demand of water-using sectors and make full use of the water supply capacity of each water supply source. When a certain convergence condition is met (such as the change in the water intake coefficient being less than a preset threshold), the iteration process ends, and the water intake coefficient obtained at this time is the final value.

[0059] Daily water supply volume is the amount of water provided by a water source to a specific water user on a given day. Daily water supply surplus is the amount of water a water source can still provide on a given day, equal to the source's maximum daily supply capacity minus the amount already allocated that day. Daily water demand surplus is the unmet water demand of a water user on a given day, equal to the user's total water demand for that day minus the amount already received from various water sources.

[0060] Optionally, a first parameter can be calculated based on the daily remaining water demand of the water user and the water intake coefficient of the water user from the first priority water source. Then, the daily remaining water supply of the water source and the first parameter can be compared. If the first parameter is less than or equal to the daily remaining water supply, the daily water supply from the water source to the water user is equal to the first parameter. If the first parameter is greater than the daily remaining water supply, the daily water supply is equal to the daily remaining water supply. Finally, the original daily remaining water demand is subtracted from the daily water supply provided by the water source to obtain the new daily remaining water demand of the water user, thus updating the daily remaining water demand.

[0061] Step 106: Take the new daily water demand as the daily water demand of the water-using department, and perform the determination steps for other priority water sources in sequence to determine the maximum daily water supply to the water-using department for each priority water source.

[0062] It is understandable that steps 106 and 104 together form an iterative process. The purpose is to use other priority water sources in turn to meet the remaining water demand when the first priority water source cannot fully meet the daily water demand of the water-using sector, until the daily water demand of the water-using sector is met or the water supply capacity of all water sources is exhausted, thereby achieving a rational allocation of water resources.

[0063] Optionally, step 104 can be repeated for the remaining water sources in order of priority until the daily water demand of the water user is met or the water supply capacity of all water sources is exhausted.

[0064] Specifically, the daily water supply from the water source to the corresponding water user department can be iteratively updated according to the following calculation formula:

[0065] ;

[0066] In the formula, It is the sequence number of the target region; Represents a specific water source; Represents the specific water-using department; Represents a certain day; yes The day number is Water users in the target area water supply source The demand, i.e., the water supply source Water supply department Daily water supply. It is a water supply source For water users The water intake coefficient, i.e., the water user department water source The water intake coefficient; yes The day number is Water users in the target area The remaining daily water demand; yes The day number is Water supply sources within the target area The remaining daily water supply. Of which, The value will be based on The value is updated dynamically; similarly... The value will also depend on The value is updated dynamically until the daily water demand of the water-using sector is met or the water supply capacity of all water sources is exhausted.

[0067] The aforementioned water allocation method first identifies at least one water source for each water-using sector in the target area. Then, for the first-priority water source, a determination step is performed. This step includes determining the daily water supply from the water source to the water-using sector based on the source's daily remaining water supply and a first parameter. Based on the source's daily water supply, a new daily remaining water demand for the water-using sector is determined. The first parameter is the product of the water-using sector's water intake coefficient from the water source and its daily remaining water demand. This new daily remaining water demand is then used as the daily remaining water demand for the water-using sector. The determination steps are then performed sequentially for other priority water sources to determine the daily water supply from each priority water source to the water-using sector. Thus, by considering the priority of water supply sources and the remaining demand of water-using sectors, and by iteratively adjusting the allocation scheme in real time based on the daily remaining water supply and daily remaining water demand, the accuracy and reliability of water supply allocation for each water-using sector in the target area under a complex water network can be improved, while also enhancing the flexibility of water resource allocation.

[0068] In one embodiment, the method further includes: determining the maximum daily water supply capacity of each water source for each water-using department, based on the type of each water source.

[0069] As can be seen from the above, the types of water supply sources include Class I external water transfer (inter-regional water transfer), Class II external water transfer (inter-river water transfer), reclaimed water (recycled water after sewage treatment), local surface water and groundwater, etc.

[0070] Optionally, detailed water quota standards can be determined based on factors such as the type of water-using sector and production process. For example, for agricultural water-using sectors, the daily irrigation water quota per acre of farmland can be determined based on the planting area and growth stage of different crops; for industrial water-using sectors, the daily water quota can be determined based on the water consumption per unit of product. Then, taking into account factors such as water quality, quantity, supply cost, and reliability of water sources, priorities can be set for different types of water sources. For example, the first type of externally diverted water can be set as the first priority because its water quality is relatively stable and less affected by the season. Finally, the daily water supply can be allocated to water-using sectors in order of priority. First, the water supply from the first priority source can be used to meet the water demand of the water-using sector. When the water supply from the first priority source is insufficient, the water supply from the second priority source can be used, and so on, until the water quota of the water-using sector is met or the water supply from all sources is exhausted.

[0071] Understandably, determining the daily water supply based on the type of water source can better meet the diverse water needs of different water users. For example, domestic water users, who have higher requirements for water quality, can prioritize the use of Class I imported water or surface water that has undergone deep treatment. In addition, by rationally allocating the daily water supply of each type of water source, the advantages of each water source can be fully utilized, reducing dependence on a single water source and thus improving the stability and reliability of the water supply system in the target area.

[0072] In one embodiment, such as Figure 2 As shown, for each water source type corresponding to the water user department, the maximum daily water supply capacity of each water source is determined, including:

[0073] Step 202: When the water source is reclaimed water, determine the maximum daily water supply of reclaimed water based on the product of the reuse coefficient and the second parameter.

[0074] The reuse factor characterizes the capacity to convert the previous day's domestic and industrial water consumption into reclaimed water. It reflects the proportion of treated wastewater that can be reused as reclaimed water and is a key parameter for calculating reclaimed water supply capacity. The reuse factor can be determined based on the proportion of non-conventional water source supply to the sum of domestic and industrial water consumption, as published by relevant departments; the reuse factor is close to this proportion. The second parameter is the sum of historical daily water consumption in the domestic sector and the industrial sector. This second parameter is the fundamental data for calculating reclaimed water supply capacity. Combined with the reuse factor, the reclaimed water supply capacity can be determined because reclaimed water is mainly generated from domestic and industrial wastewater. Therefore, the previous day's domestic and industrial water consumption can be used to estimate the current day's reclaimed water supply capacity.

[0075] Optionally, the maximum daily water supply capacity of reclaimed water can be determined using the following formula:

[0076] ;

[0077] In the formula, yes The day number is The water supply capacity of the target area for reclaimed water, that is, the maximum daily water supply of reclaimed water; It is the reuse coefficient, i.e., the reclaimed water utilization coefficient; yes The day number is Water consumption of domestic water users in the target area; yes The day number is The water consumption of industrial water-using sectors in the target area.

[0078] Step 204: When the water source is classified as Class I external water transfer, determine the maximum daily water supply of Class I external water transfer based on the product of the annual water supply of Class I external water transfer and the allocation coefficient of Class I external water transfer.

[0079] The first category of water transfer allocation coefficient is used to downscale and discretize the total annual water supply capacity of the first category of water transfer to each target area on a daily basis, so as to achieve a reasonable allocation of the water supply capacity of the first category of water transfer in different target areas and at different times. The first category of water transfer allocation coefficient for each target area at different times can be determined comprehensively based on factors such as water demand, population distribution, industrial layout, and the coverage and transmission capacity of water supply sources in the target area.

[0080] Optionally, the maximum daily water supply for Category I external water transfer can be determined using the following formula:

[0081] ;

[0082] In the formula, yes The day number is The target area's first-class external water supply capacity, i.e., the maximum daily water supply of reclaimed water; This is the annual water supply volume of the first category of externally diverted water; yes The day number is The first type of external water allocation coefficient for the target area, and Satisfy the normalization condition: .

[0083] Step 206: When the water source is local surface water, determine the maximum daily water supply of local surface water according to the preset surface water model.

[0084] The preset surface water model can be a common surface water model (Community Water Model, CWatM). This model can calculate the surface water supply capacity, i.e. the local surface water supply, based on the reservoir storage, lake storage, and river storage. Then, the maximum daily surface water supply can be determined based on the local surface water supply.

[0085] Step 208: When the water source is local groundwater, determine the maximum daily water supply of local groundwater according to a preset algorithm.

[0086] Optionally, the preset algorithm may first acquire daily precipitation data for the target area, and then determine the precipitation infiltration coefficient by combining local soil type, vegetation cover, and other factors. The precipitation infiltration coefficient is then multiplied by the daily precipitation to obtain the amount of water replenished to the ground due to precipitation infiltration. Next, based on the acquired parameters such as surface water level and flow rate, the recharge relationship between surface water and groundwater is analyzed to calculate the daily recharge of groundwater from surface water. Finally, based on the hydrogeological conditions surrounding the target area, the boundary location and intensity of lateral recharge are determined, and the calculation... The process involves calculating the daily recharge of groundwater flowing laterally into the area; obtaining the evaporation capacity of the target area using meteorological data, and determining the groundwater evaporation coefficient by combining factors such as groundwater level depth and vadose zone lithology, to calculate the daily groundwater discharge due to evaporation; then, based on the groundwater flow direction and boundary conditions around the target area, calculating the daily groundwater discharge flowing laterally out of the target area; finally, according to the principle of water balance, the difference between groundwater recharge and discharge within a certain time period equals the change in groundwater storage in the target area. For example, in a short period (e.g., one day), assuming the change in storage is relatively small and negligible, the maximum daily groundwater supply can be approximately equal to the recharge minus other non-artificial extraction discharge. In other words, the maximum daily groundwater supply is obtained by subtracting the discharge (evaporation discharge + lateral discharge) from the recharge (precipitation infiltration recharge + surface water recharge + lateral recharge).

[0087] In this embodiment, different calculation methods are used for different types of water supply sources, which can more accurately simulate the daily water supply of each water supply source and provide more accurate data support for the rational allocation and management of water resources. In addition, the water supply capacity is calculated to each grid on a daily basis, realizing a refined simulation of the water supply capacity in space and time, which can better meet the water demand analysis of different regions and different times.

[0088] In one embodiment, such as Figure 3 As shown, based on a preset algorithm, the maximum daily groundwater supply is determined, including:

[0089] Step 302: Obtain the water yield and water storage rate of the underground aquifer in the target area.

[0090] The specific yield is the ratio of the volume of water that can be freely discharged from an aquifer under gravity in a target area to the total volume of the aquifer. Specific yield characterizes the proportion of water that an aquifer can release during gravity drainage, reflecting the aquifer's water release capacity under gravity. Specific yield is mainly related to factors such as the porosity, particle size, and arrangement of the aquifer. The storage capacity is the amount of water stored or released per unit volume of aquifer when the hydraulic head changes by one unit, due to the elastic compression of the aquifer and the elastic expansion of the water. Storage capacity characterizes the aquifer's ability to store or release water due to elastic deformation when the hydraulic head changes. Storage capacity is related to the elastic properties of the aquifer and the compressibility of water.

[0091] Optionally, the specific yield and storage capacity of an underground aquifer can be determined through field tests such as pumping tests and injection tests. In pumping tests, data such as pumping volume and water level changes are monitored, and the specific yield and storage capacity are calculated using relevant hydrogeological formulas. Alternatively, they can be determined based on existing hydrogeological data specific to the target area.

[0092] Step 304: Determine the first water storage capacity of the underground aquifer based on the water yield, and determine the second water storage capacity of the underground aquifer based on the water storage rate.

[0093] The first water storage is the water storage of the aquifer determined based on the specific yield. The first water storage reflects the amount of freely drainable water that the aquifer can provide under gravity. The second water storage is the water storage of the aquifer determined based on the storage ratio. The second water storage reflects the amount of water stored or released due to changes in hydraulic head caused by elastic compression of the aquifer and elastic expansion of water.

[0094] Optionally, the first water storage volume can be calculated using the following formula:

[0095] ;

[0096] In the formula, yes The day number is The primary water storage of groundwater in the target area; It refers to the water supply degree; It refers to the thickness of the underground aquifer; The serial number is The area of ​​the underground aquifer in the target area; For the serial number The target area is Sun saturation, The saturation level can be obtained by smoothing the ratio of the water head relative to the bottom plate height to the thickness of the underground aquifer. Smoothing is performed to enable the calculation of partial derivatives within the model.

[0097] Then calculate the second water storage capacity using the following formula:

[0098] ;

[0099] In the formula, yes The day number is The second water storage of groundwater in the target area; It refers to the water storage rate.

[0100] Step 306: Determine the maximum daily water supply of local groundwater based on the weighted sum of the first and second water reserves.

[0101] Optionally, the maximum daily groundwater supply can be determined using the following formula:

[0102] ;

[0103] In the formula, yes The day number is The maximum daily water supply of local groundwater in the target area; It is a pre-set groundwater extraction coefficient, when Groundwater extraction is permitted only when the temperature is greater than a certain value; when... At that time, groundwater extraction is prohibited, and when setting up When conducting research, it is necessary to comprehensively consider factors such as the groundwater level, aquifer characteristics, and water resource protection requirements of the target area to ensure the rational extraction and sustainable use of groundwater.

[0104] In this embodiment, the water storage and release capacity of the underground aquifer under both gravity drainage and elastic water release conditions are comprehensively considered, which can more comprehensively and accurately reflect the actual water supply capacity of the underground aquifer in the target area. In addition, by introducing the water level change and time-related coefficients, the dynamic changes of the groundwater level over time are considered, making the calculation results more consistent with the actual situation and helping to grasp the local groundwater supply capacity of the target area in real time and accurately.

[0105] In one embodiment, the method further includes: determining the daily water demand of each water-using sector based on the type of each water-using sector within the target area.

[0106] Alternatively, the daily water demand of each water-using sector can be determined based on water quotas and population and industry scale. Taking the agricultural water-using sector as an example, the planting area of ​​various crops can be determined first; then the irrigation water quota for each crop can be found; then the planting area of ​​each crop can be multiplied by the corresponding irrigation water quota, and the utilization coefficient of irrigation water can be considered to obtain the daily water demand of the agricultural sector.

[0107] Understandably, determining the daily water demand of each water-using sector based on its type within the target area can prevent some sectors from overusing water while others are underusing it, thus ensuring the rational allocation of water resources.

[0108] In one embodiment, such as Figure 4 As shown, based on the type of water-using sector within the target area, the daily water demand of each water-using sector is determined, including:

[0109] Step 402: If the water-using sector is a domestic water-using sector, determine the daily water demand of the domestic water-using sector based on the ratio of the population of the target area to the total population of the corresponding superior area, the historical annual water consumption of the domestic water-using sector, and the domestic water demand allocation coefficient.

[0110] The ratio of the population of the target area to the total population of its corresponding superior region is defined as the ratio of the population of the target area to the total population of its corresponding superior region. The superior region refers to the aforementioned total region with clearly defined boundaries and water demand. The historical annual water consumption of the domestic water sector is the total water actually consumed by the domestic water sector within the target area in the past year, which can be determined based on historical water resource data published by relevant departments. The domestic water demand allocation coefficient is a factor that varies with time. The relevant coefficient is used to allocate the total annual water demand of the domestic water sector to each day of the year. The domestic water demand allocation coefficient can be obtained by statistical analysis based on historical daily domestic water consumption data, such as calculating the proportion of water consumption per day to the total annual water consumption, averaging these proportions.

[0111] Step 404: If the water-using sector is an industrial water-using sector, determine the daily water demand of the industrial water-using sector based on the ratio of the population of the target area to the total population of the corresponding superior area, the historical annual water consumption of the industrial water-using sector, and the industrial water demand allocation coefficient.

[0112] The industrial water demand allocation coefficient is used to distribute the total annual water demand of industrial water users to each day of the year. Similar to the domestic water demand allocation coefficient, the industrial water demand allocation coefficient can be obtained by analyzing the daily water consumption data of industrial water users in the target area over many years, and analyzing the water consumption fluctuations on different days. For example, the proportion of water consumption per day to the total annual water consumption can be calculated, and the industrial water demand allocation coefficient can be obtained after averaging and other processing.

[0113] Optionally, the daily water demand of domestic or industrial water-using sectors can be determined using the following formula:

[0114] ;

[0115] In the formula, Target area Water departments within (Domestic water use department or industrial water use department) in Daily water demand, that is, the daily water demand of domestic water use sector or industrial water use sector; It is the water user department The historical annual total water consumption of (domestic water use sector or industrial water use sector), such as the annual total demand for domestic water or the annual total demand for industrial water. The population of the target area Total population of the parent region corresponding to the target region The ratio; when Target area The domestic water supply department Daily water demand It is the water demand allocation coefficient for domestic use; when Target area Industrial water departments within Daily water demand yes The daily industrial water demand allocation coefficient, and Satisfy the normalization condition: .

[0116] Step 406: If the water-using sector is an agricultural water-using sector, determine the daily water demand of the agricultural water-using sector based on the historical annual total water consumption of the agricultural water-using sector and the agricultural demand allocation coefficient.

[0117] The agricultural demand allocation coefficient is used to allocate the total annual water demand of the agricultural water sector to different target areas and different dates (times). Information such as the planting distribution and growth status of different crops in the target area can be obtained through satellite remote sensing. Combined with meteorological data, soil moisture data, etc., the proportion of agricultural water demand for different targets on different dates to the total annual agricultural water demand can be determined, thus obtaining the agricultural demand allocation coefficient.

[0118] Alternatively, the daily water demand of the agricultural water sector can be determined using the following formula:

[0119] ;

[0120] In the formula, Target area Agricultural water departments within exist Daily water demand, that is, the daily water demand of the agricultural water sector; Agricultural water use department The historical annual water consumption, such as the total annual agricultural demand; yes Daily target area The agricultural water demand allocation coefficient, and Satisfy the normalization condition: In addition, the water source for ecological water replenishment of rivers and lakes is surplus water resources other than groundwater, so no separate ecological water replenishment requirement is set in this embodiment.

[0121] In this embodiment, for different types of water-using sectors, the annual water demand is downscaled to daily water demand and discretized to the target area. This ensures that the water demand data matches the surface water model and groundwater model to be coupled in terms of time step and spatial resolution, which is beneficial for subsequent model coupling and water resource simulation analysis. In addition, in future forecasts, different future water demand scenarios can be assumed by adjusting parameters such as the water demand allocation coefficient, providing multiple possibilities for water resource planning and management, thereby helping to formulate more scientific and reasonable water resource management strategies.

[0122] Furthermore, it should be noted that in some embodiments, all parameters involved in the iterative process of the water intake allocation method of this application can be automatically calibrated based on the Non-dominated Sorting Genetic Algorithm II (NSGA-II). To balance the model's simulation performance in terms of water intake and groundwater storage, this application uses the average groundwater depth and annual local surface water extraction volume as calibration targets, and uses the annual groundwater extraction volume as an independent validation variable. Specifically, firstly, the water intake allocation model parameters are set according to the conditions of the target area (refer to Table 1). If necessary, the water intake model parameters can be calibrated together with the parameters to be calibrated in the coupled surface water model and groundwater model (refer to Table 2). Secondly, the value range of the parameters to be calibrated is set, and the Pareto front is obtained through automatic calibration using the NSGA-II algorithm. Thirdly, the parameter set in the Pareto front that simulates groundwater depth well is selected, while also considering the simulation effect of surface water extraction volume. Finally, the annual groundwater extraction simulated by the model is compared with the water resources bulletin (historical water resources data for the target area) to verify the reliability of the calibrated model. Verifying the reliability of the calibrated model involves determining whether it meets preset conditions: whether the root mean square error of the burial depth is within 0.5 meters, whether the relative error between the annual local surface water extraction and the water resources bulletin value is less than 10%, and whether the relative error between the annual groundwater extraction and the water resources bulletin value is less than 10%. If the root mean square error of the burial depth is within 0.5 meters, the relative error between the annual local surface water extraction and the water resources bulletin value is less than 10%, and the relative error between the annual groundwater extraction and the water resources bulletin value is less than 10%, the calibrated model is considered to have high reliability and can be used for subsequent water resources allocation. Otherwise, iteration continues until the reliability of the calibrated model meets the preset conditions.
