Problems solved by technology

Therefore, there are many issues to be considered in the quota method, and it is often difficult to determine such complete data in actual operation, so the operation is more cumbersome
[0004] At the same time, the mining volume of agricultural irrigation mining wells is small, but the number of mining wells on the regional surface is huge, and the well-by-well measurement is difficult to promote in a large area. At present, the quota method and the mu method are generally used in China to estimate the regional agricultural irrigation mining volume. , but the precision of the data result is low

[0066] see figure 1 , an embodiment of the present invention provides a calculation method for groundwater exploitation, including:

[0067] Step 101, determining the first preset number of crops in the preset area as typical crops;

[0068] Typical crops need to be representative in the preset area, and their planting area is larger or the proportion of the area is slightly smaller but more important. The first preset number needs to be selected according to the preset area, and the preferred range of values ​​is 5-8.

[0069] Step 102, according to each of the typical crops, determine a typical area for planting each of the typical crops, wherein the typical area includes more than a second preset number of groundwater production wells;

[0070] For the typical crops with larger planting area mentioned above, each typical crop preferably selects at least 2 typical areas for planting the typical crops. In an embodiment of the present invention, each typical area includes at...

[0081] see figure 2 , further, for the first embodiment, the step of determining the first preset number of crops in the preset area as typical crops includes:

[0082] Step 201, obtaining the planting area of ​​each crop and the water demand per unit area of ​​each crop in the preset area;

[0083] Step 202, sort the planting area of ​​each of the crops in descending order, and determine that the top third preset number of crops in the sorting are typical crops, wherein the third preset number is smaller than the first preset number set quantity;

[0084] Step 203, sort the water demand per unit area of ​​each of the crops from large to small, and obtain the first fourth preset number of crops in the sorting, when the planting of the first fourth preset number of crops in the sorting When the area is greater than the preset area, it is determined that the crop is a typical crop, wherein the fourth preset number is smaller than the first preset number.

[0088] see image 3 , further, for the first embodiment, according to the extraction amount of electricity per kWh of the groundwater extraction wells in each of the typical areas and the power consumption of the groundwater extraction wells, obtain each of the typical areas The steps for determining the actual extraction volume of the groundwater extraction well include:

[0089] Step 301: Obtain the actual production volume of the deep-water wells in each typical area according to the production volume per unit of electricity of the deep-water wells in each typical area and the power consumption of the deep-water wells;

[0090] Step 302 , according to the production amount per kWh of the shallow water wells in each typical area and the power consumption of the shallow water wells, the actual production volume of the shallow water wells in each typical area is obtained.

[0091] In order to make better use of groundwater extraction data, in this embodiment, deep water wells...

Abstract

The invention provides a method and a device for calculating the exploitation amount of groundwater. The method for calculating the exploitation amount of groundwater comprises the following steps: determining a first preset number of crops in a preset region as typical crops; determining a typical region for planning each typical crop according to each typical crop; acquiring the exploitation amount per kilowatt hour of a groundwater well and the electricity consumption of the groundwater well in each typical region, and getting the actual exploitation amount of the groundwater well in each typical region; getting the exploitation amount of groundwater per unit area of each typical crop according to the actual exploitation amount of the groundwater well in each typical region and the planting area of the typical crops in the typical regions; and getting the exploitation amount of groundwater according to the exploitation amount of groundwater per unit region of each typical crop and the planting region of each typical crop. According to the method for calculating the exploitation amount of groundwater provided by one embodiment of the invention, the exploitation amount is reversely deduced according to agricultural electricity data, and the reliability and accuracy of data are higher.

Description

technical field [0001] The invention relates to the technical field of water conservancy, in particular to a calculation method and device for groundwater exploitation. Background technique [0002] In recent years, water resources are in short supply, and many areas have had to overexploit groundwater for a long time in order to maintain economic and social development. As a result, a series of geological and groundwater eco-environmental problems have been caused, such as deep and shallow groundwater level funnels, land subsidence, and the downward movement of salty and fresh water interfaces. Therefore, it is imminent to count the amount of groundwater exploitation and control the problem of groundwater. [0003] The assessment of agricultural water consumption generally adopts the quota method, but the quota method needs to pay attention to the crop planting structure and the multiple cropping index, and the irrigation water demand obtained by the quota method is the ne...
