[0103] Below, in conjunction with a specific small irrigation area water consumption estimation scenario application example, the solution of the embodiment of the present application is described in detail and explained:

[0104] In an embodiment of the present application, a method for estimating water consumption in small irrigation areas based on water metering model matching is provided. The method can be applied to match typical sample irrigation areas that best match the characteristics, morphology, crop structure and other information of the small irrigation areas to be promoted, thereby obtaining the optimal per-mu water consumption of the irrigation areas, thereby achieving accurate estimation of the irrigation water consumption of the small irrigation areas to be promoted and the water consumption of the small irrigation areas in the areas where the small irrigation areas to be promoted are located.

[0105] Specifically, refer to Figure 2 , the embodiment of the present application can be further implemented as follows:

[0106] (1) Select sample irrigation areas and establish a sample library of water consumption estimation models for the sample irrigation areas.

[0107] Reference Figure 3 , through on-site investigation and review of the current status, water source conditions, and distribution of main and branch channels and water diversion outlets of the sample irrigation areas to be selected as the water consumption estimation of small irrigation areas, determine whether the selected sample irrigation areas meet the measurement conditions, and divide the characteristics according to representative factors such as irrigation area terrain, irrigation area morphology, irrigation area planting structure, agricultural irrigation zone, and administrative division. Through comparison, screening and adjustment, finally select the most representative N small irrigation areas with good on-site conditions as sample irrigation areas. From the perspective of fully mastering the water use process, a certain number of metering equipment is installed according to the characteristics of different irrigation areas to obtain data such as precipitation, soil moisture, water level, and flow. At the same time, according to the conditions of irrigation area hydrological cycle, runoff, water source water, etc., hydrological cycle simulation model, water resource allocation model, water source water volume prediction model and other modules are established respectively, and finally the water volume estimation model of sample irrigation areas with different irrigation area characteristics is obtained, thereby establishing a sample library of water volume estimation models of sample irrigation areas representing the characteristics of N different irrigation areas.

[0108] (2) Obtain monitoring data on water volume, soil moisture and rainfall in the sample irrigation area during the entire agricultural irrigation process.

[0109] According to the irrigation area, water source type, crop planting structure, on-site conditions, management tasks and requirements of the selected sample irrigation area, the installation location, model and quantity of metering equipment are determined, and the monitoring points are arranged scientifically and rationally. From the perspective of fully mastering the water intake process, monitoring and metering construction is carried out in each typical small irrigation area, and water volume monitoring points are set up at the main water source, secondary water source, main water intake of trunk, branch and ditch, water intake for domestic and industrial water, abandoned (return) water outlet and water diversion outlet. For the main crops in the irrigation area (should be no less than 4 types), typical plots are selected and soil moisture monitoring points are set up. The metering equipment is further optimized and supplemented from the process of channel water intake, water delivery, water diversion, abandoned water and crop water use. Combined with rainfall, crop stratification water consumption and shallow groundwater data, the water volume, soil moisture and rainfall monitoring data of the whole process of agricultural irrigation are obtained.

[0110] (3) Construct a small irrigation district model matching index system.

[0111] The matching of small irrigation area calculation model includes two categories: input indicators and output indicators. The factors that have a significant impact on the water consumption of the irrigation area are mainly selected as the main parameters that can comprehensively and objectively characterize the current situation, characteristics, and water use functions of the irrigation area. The indicators are divided into direct indicators and indirect indicators. Direct indicators can be directly obtained through on-site measurement, equipment monitoring data, existing data import or other means; indirect indicators can be calculated or converted based on direct indicators.

[0112] Reference Figure 4 The input indicators mainly include water intake indicators and water use indicators. Specifically, 13 key factors that have a significant impact on the water use in the irrigation area are selected. Among them, the water intake indicators include rainfall (for example, from March to October), water diversion, water abandonment, groundwater depth in the irrigation area, flow rate, flood storage flow, proportion of fish pond area in the irrigation area, and proportion of reused water; the water use indicators include the proportion of water-saving irrigation projects in the irrigation area, the proportion of rice planting area, soil infiltration rate, irrigation area morphology index, and main canal slope. The input indicators focus on the per-mu water use indicator and give recommended reference values, which can provide a reference for the review of the data of the irrigation area water use direct reporting system.

[0113] Reference Figure 5 The output indicators include water intake, water use and water abandonment (including sub-items of average water use per mu), the specific contents are as follows: Figure 5 shown.

[0114] Further, the meanings of the above indicators are introduced as follows:

[0115] Precipitation: Precipitation refers to the annual precipitation from March to October. The data is obtained through meteorological station monitoring and is measured in mm (millimeter). The calculation system uses the precipitation data of typical small irrigation areas obtained through the established rainfall monitoring station equipment. Other typical small irrigation areas can be obtained based on the meteorological stations in or near the irrigation area.

[0116] Water diversion: Water diversion includes the water diversion from surface water sources (including surface water sources and groundwater sources combined) and groundwater sources in each irrigation area. This indicator is mainly characterized by the water diversion from the main water source and the proportion of auxiliary water sources. The water diversion from the main water source and auxiliary water source is obtained through metering and monitoring equipment. If the auxiliary water source does not meet the metering conditions, it is obtained by conversion.

[0117] Amount of abandoned water: Amount of abandoned water refers to the amount of water abandoned from channels that do not participate in the irrigation process in the irrigation area. When it cannot be measured, it can be estimated according to the conventional water volume ratio, and a small amount can be ignored.

[0118] Groundwater depth: Groundwater depth refers to the depth of groundwater in the irrigation area, that is, the distance from the groundwater surface to the ground surface. It is characterized by the upper and lower limits of the groundwater depth. The depth data of the water surface from the ground of conventional shallow water wells can be used.

[0119] Runoff: Runoff refers to the process of forming net rain after deducting rainfall losses. Rainfall losses include plant interception, infiltration, filling and evaporation, among which infiltration is the main one. Runoff refers to the amount of water that forms runoff from rainfall, measured in mm.

[0120] Flood storage capacity: Flood storage capacity refers to the amount of water that is discharged through the irrigation canal system but not used for farmland irrigation. It is calculated by measuring the flow through the canal during rainfall and the increase in normal flow.

[0121] Fish pond area ratio: refers to the ratio of fish pond area to irrigation area in the irrigation area. In some irrigation areas, the fish pond replenishment area is large, and the fish pond drainage volume should be calculated. The fish pond drainage volume is calculated by multiplying the fish pond area by the number of water changes in the fish pond.

[0122] Recycled water volume: Recycled water volume mainly includes the reciprocating flow volume of the upstream and downstream water systems in the irrigation area and the irrigation return water volume. It is characterized by the proportion of recycled water volume to the water diversion volume. The reciprocating flow volume of the irrigation area is characterized by the irrigation area terrain and canal system complexity coefficient. Irrigation return water is the part of deep seepage water that is difficult to completely avoid during the irrigation process and returns to the water resource circulation system. It is characterized by the irrigation water regression coefficient.

[0123] The proportion of water-saving irrigation project area: The proportion of water-saving irrigation project area refers to the proportion of the irrigation area irrigated by sprinkler irrigation, micro-irrigation, pipeline water supply, channel anti-seepage and other engineering and technical measures to the irrigation area of ​​the irrigation area. The irrigation area of ​​sprinkler irrigation, micro-irrigation and pipeline water supply can be calculated according to the relevant provisions of the Technical Standard for Water-Saving Irrigation Engineering (GB / T50363). When the standard is updated, it is calculated according to the updated standard.

[0124] Rice planting area ratio: Rice planting area ratio refers to the proportion of rice planting area in irrigation areas to the total planting area of ​​crops in irrigation areas.

[0125] Main canal slope: The main canal slope refers to the ratio of the height difference between the upstream and downstream sections of the main canal, where the bottom of the canal drops or rises along the direction of water flow, to the horizontal length of the canal section.

[0126] Irrigation area morphology index F f : The irrigation area morphological index refers to the ratio of the irrigation area of ​​the irrigation area to the maximum length from any point on the boundary to the irrigation area boundary within the measurement range of the irrigation area. The calculation formula is: F f =A / L max ; Where A is the irrigation area of ​​the irrigation district; L max It is the maximum length from any point on the boundary to the boundary of the irrigation district within the measurement range of the irrigation district.

[0127] Soil infiltration rate: refers to the rate of water infiltration per unit area of ​​soil within the irrigation area within a unit time, with the unit of mm / h. The soil type of the irrigation area adopts the soil type distribution data of the actual area.

[0128] (4) The small irrigation district to be promoted is matched with the sample irrigation district to obtain the best sample small irrigation district. The water volume calculation model of the best sample small irrigation district is the similarity model of the small irrigation district to be promoted.

[0129] The water consumption of the small irrigation district to be promoted is estimated based on the average water consumption per mu of the most similar sample irrigation district. Figure 6 The similarity model matching of small irrigation areas is realized by two different methods according to the type of irrigation area. For tidal drainage irrigation areas, the nearest neighbor principle of the distance between the irrigation area and the estuary is adopted for matching; for ordinary small irrigation areas, the multi-parameter Manhattan distance minimum principle is adopted for matching. The small irrigation areas to be promoted are matched one by one with the corresponding parameters of the sample irrigation area accounting model through the selected 13 matching indicators, and finally the best sample small irrigation area is matched.

[0130] (5) Based on the similarity model of the small irrigation district, the estimated per-mu water consumption of the small irrigation district to be promoted is calculated according to the water volume data, the soil moisture data and the rainfall monitoring data.

[0131] Furthermore, the per-mu water consumption comparison is carried out. According to the matched best sample point small irrigation area, the accounting system outputs the per-mu water consumption obtained after matching and calculation by the accounting system, and at the same time gives the recommended per-mu water consumption index of the irrigation area to be promoted according to the agricultural irrigation zone, administrative area, precipitation gradient, irrigation area form and irrigation quota of the irrigation area crop structure, as the comparison index of the estimated per-mu water consumption index obtained after matching in the irrigation area to be promoted. Examples of comparison indicators are as follows: Figure 7 shown.

[0132] Furthermore, parameter adjustment is performed. If the per-mu water consumption index obtained after matching calculation of the irrigation area to be promoted is significantly different from the five recommended per-mu water consumption indexes given by the system, the index weight is adjusted and matched again until the different per-mu water consumptions obtained are relatively close.

[0133] Furthermore, the per-mu water consumption of the small irrigation districts to be promoted is selected. Through the comparison of per-mu water consumption indicators and parameter adjustment, combined with the actual reported data of the irrigation district, the per-mu water consumption of the small irrigation districts to be promoted is selected. dt .

[0134] (6) Estimation of agricultural irrigation water consumption.

[0135] ① Agricultural irrigation water consumption W in small irrigation areas to be promoted dt . Estimation of agricultural irrigation water consumption W in small irrigation areas dt It is obtained by multiplying the recommended irrigation water consumption per mu determined by the final matching selection by the actual irrigation area of ​​the irrigation district.

[0136] W dt =M dt A dt ;

[0137] Among them, W dt Indicates the estimated agricultural irrigation water consumption in small irrigation areas (unit: 10,000 m 3 );M dt Indicates the average water consumption per mu of agricultural irrigation in the selected small irrigation area to be promoted (in m 3 );A dt It indicates the estimated actual irrigation area of ​​small irrigation districts (in ten thousand mu).

[0138] ② Calculate the agricultural irrigation water consumption W in the regional small irrigation area qy The agricultural irrigation water consumption of small irrigation areas in the estimated area is the average value of the recommended irrigation water consumption per mu determined by the final matching selection of all estimated small irrigation areas in the estimated area. qy Multiply by the actual irrigation area A of the small irrigation area in the estimated area qy .W qy The calculation formula is:

[0139] W qy =Mqy A qy ;

[0140] Among them, W qy Indicates the estimated agricultural irrigation water consumption in small irrigation areas (unit: 10,000 m 3 );M qy It indicates the average water consumption per mu recommended for all small irrigation areas in the estimated area (in m 3 );A qy It indicates the actual irrigation area of ​​small irrigation districts in the estimated area (in ten thousand mu).

[0141] Based on the recommended per-mu irrigation water consumption determined by the final matching of all estimated small irrigation areas in the estimated area, the per-mu irrigation water consumption of small irrigation areas in the estimated area is calculated by arithmetic average method. The calculation formula for the per-mu irrigation water consumption of small irrigation areas in the estimated area is as follows:

[0142]

[0143] Among them, M dti is the recommended average irrigation water consumption per mu for the i-th small-scale irrigation district to be promoted in the estimated area; n is the number of small-scale irrigation districts to be promoted in the estimated area.

[0144] In addition, the data of the irrigation area water use direct reporting system can be reviewed based on the estimated per-mu water consumption of the small irrigation area to be promoted.

[0145] In summary, the embodiments of the present application have at least the following beneficial effects:

[0146] (1) A cluster identification and matching index system for small irrigation areas based on multi-factor monitoring of the entire process of sample irrigation areas was established. The determination of input indicators provided a reference standard for the accurate matching of the small irrigation areas to be promoted with the sample irrigation areas in the sample library of the estimation model. The determination of output indicators provided a data reference for estimating and verifying the rationality and accuracy of the per-mu water consumption of the small irrigation areas to be promoted and the regional water consumption data.

[0147] (2) A method of selecting the best matching irrigation area through calculation of water consumption model of sample irrigation areas was proposed to determine the average water consumption per mu and water intake of the irrigation area to be promoted. This method effectively solved the basic problem of "how much irrigation water is consumed in county-level administrative areas and small irrigation areas" and avoided the influence of human subjective factors on agricultural water use data in irrigation areas due to the lack of metering equipment and inadequate metering conditions.

[0148] (3) A method for matching the water consumption measurement models of sample irrigation areas with tidal irrigation areas was proposed, using the nearest neighbor principle based on the distance between the irrigation area and the estuary. For ordinary small irrigation areas, a matching method was adopted based on the principle of minimum Manhattan distance among multiple parameters, including rainfall from March to October (mm), rice area percentage (%), fish pond area percentage (%), water-saving irrigation area percentage (%), irrigation area morphological index, soil infiltration rate (mm / h), etc. This method provides a new idea for accurately estimating the water consumption of small irrigation areas.
